What are the symptoms of Kallmann syndrome ? 

What are the signs and symptoms of Kallmann syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Kallmann syndrome. 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. Signs and Symptoms Approximate number of patients (when available) Abnormality of the sense of smell 90% Anterior hypopituitarism 90% Decreased fertility 90% Erectile abnormalities 90% Hypoplasia of penis 90% Abnormality of the voice 50% Breast aplasia 50% Cryptorchidism 50% Primary amenorrhea 50% Reduced bone mineral density 50% Abnormality of color vision 7.5% Cleft palate 7.5% Delayed skeletal maturation 7.5% Gait disturbance 7.5% Gynecomastia 7.5% Hemiplegia/hemiparesis 7.5% Ichthyosis 7.5% Incoordination 7.5% Muscle weakness 7.5% Muscular hypotonia 7.5% Neurological speech impairment 7.5% Nystagmus 7.5% Obesity 7.5% Pes cavus 7.5% Ptosis 7.5% Recurrent fractures 7.5% Reduced number of teeth 7.5% Renal hypoplasia/aplasia 7.5% Rocker bottom foot 7.5% Seizures 7.5% Sensorineural hearing impairment 7.5% Skeletal dysplasia 7.5% Tremor 7.5% Visual impairment 7.5% 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.
Is Kallmann syndrome inherited ? 

How is Kallmann syndrome inherited? Kallmann syndrome (KS) may be inherited in an X-linked recessive, autosomal dominant, or autosomal recessive manner depending on the gene(s) responsible. For example: KS due to mutations in the KAL1 gene (also called the ANOS1 gene), causing Kallmann syndrome 1, is inherited in an X-linked recessive manner. KS due to mutations in the FGFR1, PROKR2, PROK2, CHD7 or FGF8 genes (causing KS types 2, 3, 4, 5 and 6, respectively) is predominantly inherited in an autosomal dominant manner. KS due to mutations in PROKR2 and PROK2 can also be inherited in an autosomal recessive manner. In the majority of people with KS, the family history appears to be negative (the condition occurs sporadically). However, affected people are still at risk to pass the disease-causing mutation(s) on to their children, or to have an affected child. The risk for each child to be affected depends on the genetic cause in the affected person and may be up to 50%. People with personal questions about the genetic cause and inheritance of KS are encouraged to speak with a genetic counselor or other genetics professional. The genetic cause in many cases remains unknown, and a thorough family history should be obtained to understand the mode of inheritance in each family and to aid in genetic testing and counseling. Information about specific features present or absent in all family members can help determine the mode of inheritance present.
What is (are) Leber hereditary optic neuropathy ? 

Leber hereditary optic neuropathy (LHON) is an inherited form of vision loss. Although this condition usually begins in a person's teens or twenties, rare cases may appear in early childhood or later in adulthood. For unknown reasons, males are affected much more often than females. This condition is caused by mutations in the MT-ND1, MT-ND4, MT-ND4L, and MT-ND6 genes.
What are the symptoms of Leber hereditary optic neuropathy ? 

What are the signs and symptoms of Leber hereditary optic neuropathy? Blurring and clouding of vision are usually the first symptoms of this disorder. These vision problems may begin in one eye or simultaneously in both eyes; if vision loss starts in one eye, the other eye is usually affected within several weeks or months. Over time, vision in both eyes worsens, often leading to severe loss of sharpness (visual acuity) and color vision. This condition mainly affects central vision, which is needed for detailed tasks such as reading, driving, and recognizing faces. In rare cases, other symptoms may occur such as heart arrhythmias and neurologic abnormalities (e.g., postural tremor, peripheral neuropathy, nonspecific myopathy, movement disorders), and a multiple sclerosis-like disorder. However, a significant percentage of people with a mutation that causes Leber hereditary optic neuropathy do not develop any features of the disorder. Specifically, more than 50 percent of males with a mutation and more than 85 percent of females with a mutation never experience vision loss or related medical problems. Additional factors may determine whether a person develops the signs and symptoms of this disorder. Environmental factors such as smoking and alcohol use may be involved, although studies of these factors have produced conflicting results. Researchers are also investigating whether changes in additional genes, particularly genes on the X chromosome, contribute to the development of signs and symptoms.

What causes Leber hereditary optic neuropathy ? 

What causes Leber hereditary optic neuropathy (LHON)? Leber hereditary optic neuropathy is a condition related to changes in mitochondrial DNA. Mutations in the MT-ND1, MT-ND4, MT-ND4L, and MT-ND6 genes cause LHON. These genes are contained in mitochondrial DNA. Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA (known as mitochondrial DNA or mtDNA). The genes related to Leber hereditary optic neuropathy each provide instructions for making a protein involved in normal mitochondrial function. These proteins are part of a large enzyme complex in mitochondria that helps convert oxygen and simple sugars to energy. Mutations in any of the genes disrupt this process. It remains unclear how these genetic changes cause the death of cells in the optic nerve and lead to the specific features of Leber hereditary optic neuropathy.

Is Leber hereditary optic neuropathy inherited ? 

How is Leber hereditary optic neuropathy (LHON) inherited? Leber hereditary optic neuropathy is an inherited condition that has a mitochondrial pattern of inheritance. The gene mutations that cause this condition are found in the mitochondrial DNA. Mitochondria are inherited from a person's mother, and as a result, only females pass mitochondrial conditions on to their children. Men can be affected, but they cannot pass the condition on to their children. Often, people who develop the features of Leber hereditary optic neuropathy have no family history of the condition. Because a person may carry a mitochondrial DNA mutation without experiencing any signs or symptoms, it is hard to predict which members of a family who carry a mutation will eventually develop vision loss or other medical problems associated with Leber hereditary optic neuropathy. It is important to note that all females with a mitochondrial DNA mutation, even those who do not have any signs or symptoms, will pass the genetic change to their children.

What is (are) Dravet syndrome ? 

Dravet syndrome is a severe form of epilepsy. The condition appears during the first year of life as frequent fever-related (febrile) seizures. As the condition progresses, other types of seizures typically occur, including myoclonus and status epilepticus. A family history of either epilepsy or febrile seizures exists in 15 percent to 25 percent of cases. Intellectual development begins to deteriorate around age 2, and affected individuals often have a lack of coordination, poor development of language, hyperactivity, and difficulty relating to others. In 30 to 80 percent of cases, Dravet syndrome is caused by changes in the SCN1A gene, which is required for the proper function of brain cells.

What is (are) Charcot-Marie-Tooth disease type 2B ? 

Charcot-Marie-Tooth disease type 2B (CMT2B) affects the peripheral nerves, the nerves running from outside the brain and spine. Common signs and symptoms include slowly progressive weakness and numbness in the feet, lower leg muscles, hands, and forearms. This type of CMT is also associated with the formation of ulcers in the hands and feet. Symptoms may start in childhood to early adulthood, although later onset (>50 years) has also been described. Symptoms of CMT2B vary but tend to be similar to that of CMT type 1. CMT2B is caused by changes in the RAB7A gene. It is inherited in an autosomal dominant fashion.

What is (are) Generalized pustular psoriasis ? 

Generalized pustular psoriasis is a severe inflammatory skin condition that can be life-threatening. Affected people develop episodes of red and tender skin with widespread pustules throughout their body. This is generally accompanied by fever, chills, headache, rapid pulse rate, loss of appetite, nausea and muscle weakness. The condition generally resolves within days or weeks; however, relapses are common. Some cases of generalized pustular psoriasis are caused by changes (mutations) in the IL36RN gene and are inherited in an autosomal recessive manner. Possible triggers for sporadic forms of the condition include withdrawal from corticosteroids, exposure to certain medications, and/or infection; however, in many cases, the underlying cause is unknown. Generalized pustular psoriasis can be life threatening, so hospitalization and a specialist's care is usually required. Affected areas are treated with topical (on the skin) compresses with emollients and/or steroid creams. Certain medications may also be recommended to manage non-skin-related symptoms.

What is (are) Salivary gland cancer, adult ? 

Salivary gland cancer is a rare disease in which cancerous cells form in the tissues of the salivary glands. The salivary glands make saliva and release it into the mouth. Saliva has enzymes that help to digest food and antibodies that help protect against infections of the mouth and throat. There are 3 pairs of major salivary glands: the parotid glands, the sublingual glands, and the submandibular glands. The National Cancer Institute provides a picture of the anatomy of the salivary glands.  Some risk factors for salivary gland cancer are older age, exposure to radiation of the head and/or neck area, and family history. Signs and symptoms of the disease may include: a lump near the ear, cheek, jaw, lip, or inside of the mouth; trouble swallowing; fluid draining from the ear; numbness or weakness in the face; and on-going pain in the face. Different types of treatment are available for patients with salivary gland cancer. Some treatments are standard (currently used by physicians) and some are being tested in clinical trials (by researchers). It is suggested that patients with salivary gland cancer have their treatment planned and managed by a team of doctors who are experts in treating head and neck cancer. Although treatment depends on the stage of the cancer, typically the following three treatments are used: (1) surgery, (2) radiation therapy, and (3) chemotherapy. [1] [2]
