Signs and Symptoms Approximate number of patients (when available) Bifid uvula - Cleft palate - X-linked inheritance - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |

information | What is Marfan syndrome ? | Marfan syndrome is a disorder of the connective tissue. Connective tissue provides strength and flexibility to structures throughout the body such as bones, ligaments, muscles, walls of blood vessels, and heart valves. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessel that distributes blood from the heart to the rest of the body (the aorta). It is caused by mutations in the FBN1 gene, which provides instructions for making a protein called fibrillin-1. Marfan syndrome is inherited in an autosomal dominant pattern. At least 25% of cases are due to a new mutation. Treatment is symptomatic and supportive. |
symptoms | What are the symptoms of Marfan syndrome ? | What are the signs and symptoms of Marfan syndrome? The signs and symptoms of Marfan syndrome vary widely in severity, timing of onset, and rate of progression. Affected individuals often are tall and lean, have elongated fingers and toes (arachnodactyly), and have an arm span that exceeds body height. Other common features include unusually flexible joints, a long and narrow face, a highly arched roof of the mouth and crowded teeth, an abnormal curvature of the spine (scoliosis), and either a sunken chest (pectus excavatum) or a protruding chest (pectus carinatum). About half of people with Marfan syndrome have a dislocated lens (ectopia lentis) in one or both eyes, and most have some degree of nearsightedness (myopia). Clouding of the lens (cataract) may occur in mid adulthood, and increased pressure within the eye (glaucoma) occurs more frequently than in people without Marfan syndrome. Most people with Marfan syndrome have abnormalities of the heart and the aorta. Leaks in valves that control blood flow through the heart can cause shortness of breath, fatigue, and an irregular heartbeat felt as skipped or extra beats (palpitations). If leakage occurs, it usually affects the mitral valve, which is a valve between two chambers of the heart, or the aortic valve that regulates blood flow from the heart into the aorta. The first few inches of the aorta can weaken and stretch, which may lead to a bulge in the blood vessel wall (an aneurysm). The increased size of the aorta may cause the aortic valve to leak, which can lead to a sudden tearing of the layers in the aorta wall (aortic dissection). Aortic aneurysm and dissection can be life threatening. The Human Phenotype Ontology provides the following list of signs and symptoms for Marfan syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition.

inheritance | Is Marfan syndrome inherited ? | How is Marfan syndrome inherited? Marfan syndrome is inherited in an autosomal dominant manner. All individuals inherit 2 copies of each gene. In autosomal dominant conditions, an individual only has to have 1 mutation in the gene to develop the condition. The mutation can be inherited from a parent, or can happen by chance for the first time in an individual. Each child of an individual with Marfan syndrome has a 50% chance of inheriting the mutation and the disorder. Offspring who inherit the mutation will have Marfan syndrome, although they could be more or less severely affected than their parent. |

information | What is Postural orthostatic tachycardia syndrome ? | Postural orthostatic tachycardia syndrome (POTS) is a rare condition that is primarily characterized by orthostatic intolerance (an excessively reduced volume of blood returns to the heart when moving from a lying down to a standing position). Orthostatic Intolerance is generally associated with lightheadedness and/or fainting that is typically relieved by lying down again. In people with POTS, these symptoms are also accompanied by a rapid increase in heartbeat. Although POTS can affect men and women of all ages, most cases are diagnosed in women between the ages of 15 and 50. The exact underlying cause of POTS is currently unknown. However, episodes often begin after a pregnancy, major surgery, trauma, or a viral illness and may increase right before a menstrual period. Treatment aims to relieve low blood volume and/or regulate circulatory problems that could be causing the condition. |

causes | What causes Postural orthostatic tachycardia syndrome ? | What causes postural orthostatic tachycardia syndrome? The underlying cause of postural orthostatic tachycardia syndrome (POTS) is poorly understood. However, episodes often begin after a pregnancy, major surgery, trauma, or a viral illness and may increase right before a menstrual period. Many researchers suspect that there may be more than one cause for the condition. The following abnormalities can be associated with POTS and may play a role in the development of the condition: Peripheral denervation - reduced nerve stimulation to certain muscles. The lower extremities are generally most affected in people with POTS. Hypovolemia - an abnormal decrease or redistribution of blood in the body Changes in venous function - more specifically, a reduction in the volume of blood that returns to the heart (venous return) when moving from a lying down to a standing position Cardiovascular deconditioning - changes in cardiovascular function Baroreflex abnormalities - the baroreflexes play an important role in blood pressure regulation. When they sense a change in blood pressure, the heart rate is adjusted and the sympathetic nerve system fibers are activated to cause the blood vessels to narrow. Increased activity of the sympathetic nervous system Although most cases of POTS appear to occur sporadically in people with no family history of the condition, some affected people report a family history of orthostatic intolerance (an excessively reduced volume of blood returns to the heart when moving from a lying down to a standing position). This suggests that genetic factors may play a role in the development of POTS in some cases. Some studies also suggest that polymorphisms in certain genes (NOS3, ADRB2) may be associated with an increased risk of developing the condition and a change (mutation) in the norepinephrine transporter gene (SLC6A2) has been identified in one family with POTS. |
inheritance | Is Postural orthostatic tachycardia syndrome inherited ? | Is postural orthostatic tachycardia syndrome inherited? Most cases of postural orthostatic tachycardia syndrome (POTS) are not thought to be inherited. Although the condition generally occurs sporadically, some people with POTS do report a family history of orthostatic intolerance (an excessively reduced volume of blood returns to the heart when moving from a lying down to a standing position). This suggests that inherited factors may play a role in the development of POTS in some families. |
exams and tests | How to diagnose Postural orthostatic tachycardia syndrome ? | How is postural orthostatic tachycardia syndrome diagnosed? A diagnosis of postural orthostatic tachycardia syndrome (POTS) is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. Many physicians will conduct a physical examination, including measuring blood pressure and heart rate while lying, sitting, and standing. A tilt table test may also be recommended to help confirm the diagnosis. |
treatment | What are the treatments for Postural orthostatic tachycardia syndrome ? | How is postural orthostatic tachycardia syndrome treated? Because postural orthostatic tachycardia syndrome (POTS) is thought to have a variety of causes, there is no single treatment that is effective for all people with the condition. In general, management of POTS aims to relieve low blood volume and/or regulate circulatory problems that could be causing the condition. In some affected people, simple life style interventions such as adding extra salt to the diet, ensuring adequate fluid intake, participating in a specialized exercise program, and avoiding factors that exacerbate the condition appear to improve symptoms. Certain medications have also been used to treat POTS with some success. |
information | What is 2-methyl-3-hydroxybutyric aciduria ? | 2-methyl-3-hydroxybutyric aciduria is an inherited disorder in which the body cannot effectively process the amino acid isoleucine.

information | What is Limb-girdle muscular dystrophy ? | Limb-girdle muscular dystrophy is a group of disorders which affect the voluntary muscles around the hips and shoulders. The conditions are progressive, leading to a loss of muscle strength and bulk over a number of years. Onset may occur in childhood, adolescence, young adulthood, or even later. Males and females are affected in equal numbers. Most forms of limb girdle muscular dystrophy are inherited in an autosomal recessive manner. Several rare forms are inherited in an autosomal dominant pattern. While there are no treatments which directly reverse the muscle weakness associated with this condition, supportive treatment can decrease the complications. There are at least 20 different types of limb-girdle muscular dystrophy. |
inheritance | Is Limb-girdle muscular dystrophy inherited ? | How is limb-girdle muscular dystrophy inherited? Limb-girdle muscular dystrophy (LGMD) is most often inherited in an autosomal recessive manner; less commonly, rare sub-types may be inherited in an autosomal dominant manner. There may be difficulties diagnosing the condition accurately, and often the mode of inheritance cannot be determined. Therefore, it may be challenging to determine the exact recurrence risks for some families. Establishing the type of LGMD in an affected individual can be useful for discussing the clinical course of the disease as well as for determining who else in the family may be at risk for the condition. |
treatment | What are the treatments for Limb-girdle muscular dystrophy ? | How might limb-girdle muscular dystrophy be treated? Unfortunately, no definitive treatments or effective medications for the limb-girdle muscular dystrophies (LGMDs) currently exist. Management depends on each individual and the specific type of LGMD that the individual has. However, a general approach to managing LGMD has been proposed, based on the typical progression and complications of affected individuals. This approach may include: weight control to avoid obesity; physical therapy and stretching exercises to promote mobility and prevent contractures (fixed tightening of the muscles); use of mechanical aids such as canes, walkers, orthotics, and wheelchairs as needed to help ambulation and mobility; monitoring and surgical intervention as needed for orthopedic complications such as foot deformity and scoliosis; monitoring respiratory function and use of respiratory aids when needed; monitoring for evidence of cardiomyopathy in the types of LGMD with known occurrence of cardiac involvement; and social and emotional support and stimulation to maximize a sense of social involvement and productivity, and to reduce the sense of social isolation common in these disorders. |
information | What is Limited cutaneous systemic sclerosis ? | Limited cutaneous systemic sclerosis is a subtype of systemic sclerosis characterized by the association of Raynaud's phenomenon and skin fibrosis on the hands, face, feet and forearms. The exact cause of limited cutaneous systemic sclerosis is unknown, but likely originates from an autoimmune reaction which leads to overproduction of collagen. In some cases, the condition is associated with exposure to certain chemicals. Management is aimed at treating the symptoms present in each affected individual. |

treatment | What are the treatments for Limited cutaneous systemic sclerosis ? | How might CREST syndrome be treated? Unfortunately, CREST syndrome has no known cure. The condition carries both physical and psychological consequences, so a holistic approach to management should be taken. Treatment generally focuses on relieving signs and symptoms and preventing complications. Heartburn may be relieved by antacid medications that reduce the production of stomach acid. Medications that open small blood vessels and increase circulation may help relieve Raynaud's symptoms and reduce increased pressure in the arteries between the heart and lungs. Drugs that suppress the immune system have shown promise in preventing interstitial lung disease (a condition in which excess collagen collects in the tissue between the lungs' air sacs) in some people with CREST syndrome. To prevent loss of mobility, stretching exercises for the finger joints are important. A physical therapist can also show affected individuals some facial exercises that may help keep the face and mouth flexible. If CREST syndrome is making it difficult to perform daily tasks, an occupational therapist can help individuals learn new ways of doing things. For example, special toothbrushes and flossing devices can make it easier to care for the teeth. Surgery may be necessary for some affected individuals. Large or painful calcium deposits sometimes need to be surgically removed, and amputation of fingertips may be necessary if skin ulcers progress to gangrene. Depression affects approximately 45% of patients with systemic sclerosis and 64% also develop anxiety, so early assessment and treatment of these psychological issues is recommended. For pain management, studies have shown that oxycodone is effective and safe for pain due to severe skin ulcers, while topical lidocaine helps reduce pain of digital ulcers in individuals with systemic scleroderma. ` There are also some lifestyle changes and home remedies that may be helpful for some individuals with CREST syndrome. To reduce Raynaud's symptoms, individuals may consider wearing gloves or mittens outdoors when the weather is cool, and indoors when reaching into the freezer, for example. To maintain the body's core temperature, individuals may dress in layers and wear a hat or scarf, thermal socks, and well-fitting boots or shoes that don't cut off the circulation. Individuals who smoke should talk to their doctor about the best ways to quit. Nicotine constricts the blood vessels, making Raynaud's phenomenon worse. Individuals who have difficulty swallowing may consider choosing soft, moist foods and chewing food well. To minimize acid reflux individuals may eat small, frequent meals; avoid spicy or fatty foods, chocolate, caffeine, and alcohol; and avoid exercising immediately before or after eating. Sitting upright for a couple of hours after a meal may also help. To help keep skin soft, individuals may avoid harsh soaps and detergents, while choosing gentle skin cleansers and bath gels with added moisturizers. Individuals may also consider bathing less frequently and taking brief baths and showers, using warm rather than hot water. Moisture levels in the home may be improved by using a humidifier to ease skin and breathing symptoms.

information | What is Coccygodynia ? | Coccygodynia is a rare condition in that causes pain in and around the coccyx (tailbone). Although various causes have been described for the condition, the more common causes are direct falls and injury. |
symptoms | What are the symptoms of Coccygodynia ? | What signs and symptoms are associated with coccygodynia? The classic symptom is pain when pressure is applied to the tailbone, such as when sitting on a hard chair. Symptoms usually improve with relief of pressure when standing or walking . Other symptoms include : Immediate and severe pain when moving from sitting to standing Pain during bowel movements Pain during sex Deep ache in the region of the tailbone |
causes | What causes Coccygodynia ? | What causes coccygodynia? A number of different causes have been associated with coccygodynia. However, the most common cause is a direct fall and injury to the area of the sacrum and coccyx. These types of injuries can occur from various activities, examples include a kick, an injury on a trampoline when one hits the bar or springs that surround the trampoline jumping pad, or from falling from a horse or skis. Another common cause, exclusive to women, is childbirth. The other most common cause of the condition is pregnancy. During the last three months of pregnancy, certain hormones are released in the women's body causing the area between the sacrum and the coccyx to soften and become more mobile. The increased mobility may result in permanent stretching and change and causing inflammation of the tissues surrounding the coccyx. In about one third of all cases of coccygodynia, the cause is unknown. Other less common causes include nerve damage, cysts such as Tarlov cysts, obesity, and a bursitis like condition that can arise in slim patients who have little buttocks fat padding. |
treatment | What are the treatments for Coccygodynia ? | What treatment is available for coccygodynia? Treatment for coccygodynia generally falls into conservative management or surgical intervention categories. The conservative approach typically includes hot sitz baths, NSAIDs, stool softeners, and/or the use of a donut-shaped pillow or gel cushion to descrease pressure and irritation of the coccyx. If these treatment options fails, glucocorticoid injections may be used in an attempt to reduce the pain. Massage therapy has also been used to help decrease pain, but most studies have shown that the relief experienced from this form of therapy is temporary. The more aggressive and rare approach involves either partial or complete removal of the coccyx (coccygectomy). |
information | What is Axenfeld-Rieger syndrome type 2 ? | Axenfeld-Rieger syndrome is a group of eye disorders that affects the development of the eye. Common eye symptoms include cornea defects, which is the clear covering on the front of the eye, and iris defects, which is the colored part of the eye. People with this syndrome may have an off-center pupil (corectopia) or extra holes in the eyes that can look like multiple pupils (polycoria). About 50% of people with this syndrome develop glaucoma, which is a serious condition that increases pressure inside of the eye. This may cause vision loss or blindness. Click here to view a diagram of the eye. Even though Axenfeld-Rieger syndrome is primarily an eye disorder, this syndrome is also associated with symptoms that affect other parts of the body. Most people with this syndrome have distinctive facial features and many have issues with their teeth, including unusually small teeth (microdontia) or fewer than normal teeth (oligodontia). Some people have extra folds of skin around their belly button, heart defects, or other more rare birth defects. There are three types of Axenfeld-Rieger syndrome and each has a different genetic cause. Axenfeld-Rieger syndrome type 1 is caused by spelling mistakes (mutations) in the PITX2 gene. Axenfeld-Rieger syndrome type 3 is caused by mutations in the FOXC1 gene. The gene that causes Axenfeld-Rieger syndrome type 2 is not known, but it is located on chromosome 13. Axenfeld-Rieger syndrome has an autosomal dominant pattern of inheritance. |

treatment | What are the treatments for Epidermolysis bullosa simplex, generalized ? | How might epidermolysis bullosa simplex be treated? There is no cure for epidermolysis bullosa simplex and there is no known treatment proven to completely control all of the symptoms. However, many complications can be lessened or avoided through early intervention. Individuals with milder forms of the disease have minimal symptoms and may require little or no treatment. In all cases, treatment is directed towards the symptoms and is largely supportive. This care should focus on prevention of infection, protection of the skin against trauma, attention to nutritional deficiencies and dietary complications, minimization of deformities and contractures, and the need for psychological support for the patient and other family members. Detailed information regarding prevention of blisters, care of blisters and infections, and management of nutritional problems can be accessed through the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and article from the eMedicine journal. |

The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
causes | What causes Fowler's syndrome ? | What causes Fowlers syndrome? The cause of Fowler's syndrome is not known. The association of Fowlers syndrome and polycystic ovaries in some patients raises the possibility that the syndrome is linked in some way to impaired muscle membrane stability, owing possibly to a hormonal abnormality. The involvement of such a hormonal abnormality may also explain why it primarily affects premenopausal women. |
exams and tests | How to diagnose Fowler's syndrome ? | How is Fowlers syndrome diagnosed? Diagnosis of Fowlers syndrome involves ruling out neurological or laboratory features that would support a diagnosis of a underlying neurological disease, and identification of a bladder capacity of over 1 liter with no sensation of urgency. Also in Fowlers syndrome, analysis of the striated muscle of the urethral sphincter using concentric needle electrode examination reveals a fairly unique electromyographic (EMG) abnormality. This EMG abnormality is found in association with the urethral sphincter (group of muscles which surround the urinary passage below the bladder), and consists of a type of activity that would be expected to cause inappropriate contraction of the muscle (i.e., impair sphincter relaxation). |
treatment | What are the treatments for Fowler's syndrome ? | How might Fowlers syndrome be treated? The urinary incontinence caused by Fowlers syndrome may be treated by sacral neuromodulation therapy. The success rate for treatment of Fowlers syndrome with neuromodulation has been estimated to be around 70%, even in women who have been experiencing symptoms for a while. Neuromodulation therapy involves the stimulation of nerves to the bladder leaving the spine. The FDA has approved a device called InterStim for this purpose. Your doctor will need to test to determine if this device would be helpful to you. The doctor applies an external stimulator to determine if neuromodulation works in you. If you have a 50 percent reduction in symptoms, a surgeon will implant the device. Although neuromodulation can be effective, it is not for everyone. The therapy is expensive, involving surgery with possible surgical revisions and replacement. Other treatments that have been tried with little success include hormonal manipulation, pharmacologic therapy, and injections of botulinum toxin. |

information | What is Myotonia congenita autosomal dominant ? | Myotonia congenita is a genetic condition characterized by the inability of the skeletal muscles to quickly relax after a voluntary movement. The symptoms associated with the condition typically appear in childhood and vary from person to person. There are two forms of the disorder: Becker type, which is the most common form; and Thomsen disease, which is a rare and milder form. Both conditions are caused by mutations in the CLCN1 gene. However, the conditions have different modes of inheritance. The Becker type is inherited in an autosomal recessive fashion, and the Thomsen type is inherited in an autosomal dominant manner. |

information | What is Pontocerebellar hypoplasia type 1 ? | Pontocerebellar hypoplasia type 1 (PCH1) is a genetic condition that affects the development of the brain. Individuals with this condition have an unusually small and underdeveloped cerebellum, which is the part of the brain that coordinates movement. A region of the brain called the pons also fails to develop properly. The pons, which is located at the base of the brain in an area called the brainstem, transmits signals from the cerebellum to the rest of the brain. Individuals with PCH1 also experience a degeneration of the anterior horn cells. Because of the anterior horn cell involvement, this condition bears a resemblance to infantile spinal muscular atrophy, with severe muscle weakness. Other signs and symptoms of PCH1 include very weak muscle tone (hypotonia), joint deformities called contractures, a small head size (microcephaly), and breathing problems that are present at birth. Mutations in the VRK1 gene have been identified in at least one family with PCH1. The condition is inherited in an autosomal recessive manner. Most children with PCH1 live only into infancy. |
symptoms | What are the symptoms of Pontocerebellar hypoplasia type 1 ? | What are the signs and symptoms of Pontocerebellar hypoplasia type 1? Pontocerebellar hypoplasia type 1 (PCH1) may first present in the prenatal period with reduced fetal movement. Polyhydramnios may also be noted. In most cases, the condition is obvious in the newborn period when respiratory insufficiency and muscle weakness present. Multiple contractures may also be present at birth, along with other motor impairment. Mental retardation and other signs of cerebellar disruption, including visual impairment, nystagmus and ataxia, may follow the initial presentation. The Human Phenotype Ontology provides the following list of signs and symptoms for Pontocerebellar hypoplasia type 1.

causes | What causes Pontocerebellar hypoplasia type 1 ? | What causes pontocerebellar hypoplasia type 1? A specific mutations in the VRK1 gene has caused PCH1 in at least one family. Specific mutations in RARS2 and TSEN54 have also been associated with PCH1. TSEN54 mutations were identified in one case from a family with three siblings with PCH1; DNA was only available in one of the three siblings. Mutations in RARS2 were also identified in one case with PCH1. In general, there is no known genetic cause for the majority of PCH1 cases and no other genes have been linked to PCH1 yet, with the exception of rare cases associated with TSEN54, RARS2 and VRK1 mutations. In fact, only fifteen families with PCH1 have been published thus far; of these, mutations were only identified in 3 families. Further research on these and other candidate genes in PCH1 is necessary to identify mutations involved in the remaining majority of the PCH1 cases.Specific mutations in other genes have been shown to cause the various other forms of pontocerebellar hypoplasia and include the RARS2, TSEN2, TSEN34, and TSEN54 genes. Mutations in three related genes, TSEN2, TSEN34, and TSEN54, can result in PCH2. TSEN54 gene mutations can also cause PCH4 and PCH5.[2951] Mutations in the RARS2 gene can cause PCH6. The genetic cause of PCH3 is unknown. |
inheritance | Is Pontocerebellar hypoplasia type 1 inherited ? | How is pontocerebellar hypoplasia type 1 inherited? Pontocerebellar hypoplasia type 1 (PCH1) is inherited in an autosomal recessive pattern, which means both copies of the associated gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. This means that parents who are carriers of this condition have a 25% chance of having an affected child. |
treatment | What are the treatments for Pontocerebellar hypoplasia type 1 ? | How might pontocerebellar hypoplasia type 1 be treated? There is no standard therapy for pontocerebellar hypoplasia type 1. Treatment is symptomatic and supportive. |
information | What is Trichorhinophalangeal syndrome type 3 ? | Trichorhinophalangeal syndrome type 3 (TRPS3), also known as Sugio-Kajii syndrome, is an extremely rare inherited multisystem disorder. TRPS3 is characterized by short stature, sparse hair, a bulbous nasal tip and cone-shaped epiphyses (the growing ends of bones), as well as severe generalized shortening of all finger and toe bones (brachydactyly). The range and severity of symptoms may vary from case to case. TRPS3 is caused by mutations in the TRPS1 gene which is localized to 8q24.12. TRPS3 is inherited in an autosomal dominant manner. |

information | What is Syndrome of inappropriate antidiuretic hormone ? | Syndrome of inappropriate antidiuretic hormone (SIADH) occurs when an excessive amount of antidiuretic hormone is released resulting in water retention and a low sodium level. It is most common among older people. It has many causes including, but not limited too, pain, stress, exercise, a low blood sugar level, certain disorders of the heart, thyroid gland, kidneys, or adrenal glands, and the use of certain medications. Disorders of the lungs and certain cancers may increase the risk of developing SIADH. Treatment includes fluid restriction and sometimes the use of medications that decrease the effect of antidiuretic hormone on the kidneys. |
symptoms | What are the symptoms of Syndrome of inappropriate antidiuretic hormone ? | What are the signs and symptoms of Syndrome of inappropriate antidiuretic hormone?

causes | What causes Syndrome of inappropriate antidiuretic hormone ? | What causes syndrome of inappropriate antidiuretic hormone? Many things can cause syndrome of inappropriate antidiuretic hormone (SIADH), including brain injury, brain infection, brain abscesses, subarachnoid hemorrhage, encephalitis, meningitis, Guillain-Barr syndrome, delirium tremens, multiple sclerosis, lung cancer, pancreatic cancer, thymoma, ovarian cancer, lymphoma, pneumonia, chronic obstructive pulmonary disease, lung abscess, tuberculosis, cystic fibrosis, surgery, and drugs. SIADH has also been reported in association with AIDS, temporal arteritis, polyarteritis nodosa, sarcoidosis, Rocky Mountain spotted fever, carcinoma of the cervix, olfactory neuroblastoma, and herpes zoster infection of the chest wall. Often the underlying cause of the condition can not be determined. In these cases the condition is said to be idiopathic. |
treatment | What are the treatments for Syndrome of inappropriate antidiuretic hormone ? | How might the syndrome of inappropriate antidiuretic hormone be treated? Treatment of syndrome of inappropriate antidiuretic hormone (SIADH) may involve fluid restriction, treatment of the underlying cause once determined, and medication that decreases the effect of antidiuretic hormone on the kidneys. |
information | What is Intrahepatic cholangiocarcinoma ? | Intrahepatic cholangiocarcinoma is a cancer that develops in the cells within the bile ducts; both inside and outside the liver. The terms cholangiocarinoma and bile duct cancer are often used to refer to the same condition. This condition occurs slightly more often in males than females and usually affects people who are between 50-70 years old. Signs and symptoms of intrahepatic cholangiocarcinoma include jaundice, abdominal pain, fever, weight loss, weakness and itching. Treatment options may include surgery to remove the bile duct and parts of the liver, chemotherapy and radiation. |
treatment | What are the treatments for Intrahepatic cholangiocarcinoma ? | How might intrahepatic cholangiocarcinoma be treated? Can it be cured? Surgery to completely remove the bile duct and tumor is the only option that can possibly lead to a cure for patients. The type of operation will depend on the size and location of the cancer. For cases of intrahepatic cancers that cannot be surgically removed, a liver transplantation may be an option. In some cases, a liver transplant might even cure the cancer. Finally, radiation and chemotherapy are also treatment options available for intrahepatic cholangiocarcioma either in addition to surgery or on their own. |
information | What is Neuronal ceroid lipofuscinosis 9 ? | Neuronal ceroid lipofuscinosis 9 (CLN9-NCL) is a rare condition that affects the nervous system. Signs and symptoms of the condition generally develop in early childhood (average age 4 years) and may include loss of muscle coordination (ataxia), seizures that do not respond to medications, muscle twitches (myoclonus), visual impairment, and developmental regression (the loss of previously acquired skills). The underlying genetic cause of CLN9-NCL is unknown but it appears to be inherited in an autosomal recessive manner. Treatment options are limited to therapies that can help relieve some of the symptoms. |

information | What is Williams syndrome ? | Williams syndrome is a developmental disorder that affects many parts of the body. This condition is characterized by mild to moderate intellectual disability, unique personality characteristics, distinctive facial features, and heart and blood vessel (cardiovascular) problems. Williams syndrome is caused by missing genes from a specific region of chromosome 7. The deleted region includes more than 25 genes and researchers believe that a loss of several of these genes probably contributes to the characteristic features of this disorder. Although Williams syndrome is considered an autosomal dominant condition, most cases are not inherited, but occur as random events during the formation of reproductive cells (eggs or sperm) in a parent of an affected individual. |
symptoms | What are the symptoms of Williams syndrome ? | What are the signs and symptoms of Williams syndrome? The signs and symptoms of Williams syndrome can be variable, but the disorder is generally characterized by mild to moderate intellectual disability a distinctive facial appearance, and a unique personality that combines over-friendliness and high levels of empathy with anxiety. People with Williams syndrome typically have difficulty with visual-spatial tasks such as drawing and assembling puzzles, but they tend to do well on tasks that involve spoken language, music, and learning by repetition (rote memorization). Affected individuals have outgoing, engaging personalities and tend to take an extreme interest in other people. Attention deficit disorder (ADD), problems with anxiety, and phobias are common among people with this disorder. The most significant medical problem associated with Williams syndrome is a form of cardiovascular disease called supravalvular aortic stenosis (SVAS). SVAS is a narrowing of the large blood vessel that carries blood from the heart to the rest of the body (the aorta). If this condition is not treated, the aortic narrowing can lead to shortness of breath, chest pain, and heart failure. Other problems with the heart and blood vessels, including high blood pressure (hypertension), have also been reported in people with Williams syndrome. Young children with Williams syndrome have distinctive facial features including a broad forehead, a short nose with a broad tip, full cheeks, and a wide mouth with full lips. Many affected people have dental problems such as small, widely spaced teeth and teeth that are crooked or missing. In older children and adults, the face appears longer and more gaunt. Additional signs and symptoms of Williams syndrome include abnormalities of connective tissue (tissue that supports the body's joints and organs) such as joint problems and soft, loose skin. Affected children may also have increased calcium levels in the blood (hypercalcemia) in infancy, developmental delays, problems with coordination, and short stature. Medical problems involving the eyes and vision, the digestive tract, and the urinary system are also possible. The Human Phenotype Ontology provides the following list of signs and symptoms for Williams syndrome.

Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
causes | What causes Williams syndrome ? | What causes Williams syndrome? Williams syndrome is caused by the deletion of genetic material from a specific region of chromosome 7. The deleted region includes more than 25 genes, and researchers believe that a loss of several of these genes probably contributes to the characteristic features of this disorder. CLIP2, ELN, GTF2I, GTF2IRD1, and LIMK1 are among the genes that are typically deleted in people with Williams syndrome. Researchers have found that the loss of the ELN gene is associated with the connective tissue abnormalities and cardiovascular disease (specifically supravalvular aortic stenosis) found in many people with this condition. Studies suggest that deletions of CLIP2, GTF2I, GTF2IRD1, LIMK1, and perhaps other genes may help explain the characteristic difficulties with visual-spatial tasks, unique behavioral characteristics, and other cognitive difficulties seen in people with Williams syndrome. Loss of the GTF2IRD1 gene may also contribute to the distinctive facial features often associated with this condition. Researchers believe that the presence or absence of the NCF1 gene on chromosome 7 is related to the risk of developing hypertension in people with Williams syndrome. When the NCF1 gene is included in the part of the chromosome that is deleted, affected individuals are less likely to develop hypertension. Therefore, the loss of this gene appears to be a protective factor. People with Williams syndrome whose NCF1 gene is not deleted have a higher risk of developing hypertension. The relationship between other genes in the deleted region of chromosome 7 and the signs and symptoms of Williams syndrome is unknown. |

information | What is Multiple pterygium syndrome Escobar type ? | Multiple pterygium syndrome, Escobar type is characterized by webbing of the neck, elbows, and/or knees, and joint contractures. Symptoms of Escobar syndrome are present from birth. It can be caused by mutations in the CHRNG gene. It tends to be inherited in an autosomal recessive fashion. |
symptoms | What are the symptoms of Multiple pterygium syndrome Escobar type ? | What are the signs and symptoms of Multiple pterygium syndrome Escobar type? Symptoms of multiple pterygium syndrome, Escobar type vary but may include short stature, vertebral (spine) defects, joint contractures, and webbing of the neck, armpit, elbow, knee, between the legs, and of the fingers and toes. The joint contractures may interfere with walking, making walking more difficult. Other symptoms may include down-slanting eyes, skin fold over the inner corner of the eye, a pointed, receding chin, droopy eye lids, and cleft palate. Males with Escobar syndrome may have undescended testicles at birth, and females may have absent labia majora. People with Escobar syndrome may have in-curving of the little finger, joined fingers, and rocker-bottom feet. They may also have kyphoscoliosis and other spine defects, such as fusion of the spine. Abnormal ossicles (the three small bones in the ear) may lead to conductive hearing loss. Other skeletal anomalies include rib fusions, radial head and hip dislocations, talipes calcaneovalgus (the foot points inwards and down) or club foot, and missing or underdeveloped kneecap. The Human Phenotype Ontology provides the following list of signs and symptoms for Multiple pterygium syndrome Escobar type. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
causes | What causes Multiple pterygium syndrome Escobar type ? | What causes multiple pterygium syndrome, Escobar type? Some cases of multiple pterygium syndrome, Escobar type are caused by mutations in the CHRNG gene. There are likely other causes of this syndrome as well which have not yet been identified. As a result, in some cases the cause for the syndrome can not be determined. Escobar syndrome is usually inherited in an autosomal-recessive fashion. |
exams and tests | How to diagnose Multiple pterygium syndrome Escobar type ? | How is multiple pterygium syndrome, Escobar type diagnosed? Multiple pterygium syndrome, Escobar type is diagnosed based on signs and symptoms in the patient. This syndrome should be considered in patients with webs across different body joints, particularly if additional signs and symptoms are present (e.g., subtle facial feature differences). Because skeletal birth defects (especially spine defects), are relatively common in Escobar syndrome radiographs of the complete skeleton may be helpful in diagnosis. Genetic testing for multiple pterygium syndrome, Escobar type is available on a limited basis. This testing can be done using linkage analysis or by sequencing the coding region for the gene. |
