Question: What is (are) Meningoencephalocele ?

Answer: Meningoencephalocele is a type of encephalocele, which is an abnormal sac of fluid, brain tissue, and meninges (membranes that cover the brain and spinal cord) that extends through a defect in the skull.  There are two main types of meningoencephalocele, which are named according to the location of the sac. The frontoethmoidal type is located at the frontal and ethmoid bones while the occipital type is located at the occipital bone.  Hydrocephalus, abnormalities of the eyeball and tear duct, and other findings have been associated with the condition. Some affected individuals have intellectual or physical disabilities while others have normal development and abilities.  The condition is typically congenital (present at birth) but has been reported to develop by chance in older individuals in rare cases. The underlying cause of the condition is uncertain, but environmental factors are thought to play a role. Treatment depends on the size, location and severity of the defect but mainly includes magnetic resonance imaging (MRI) to determine the severity of the defect, followed by surgery to repair it.
Question: What is (are) Progressive pseudorheumatoid arthropathy of childhood ?

Answer: Progressive pseudorheumatoid arthropathy of childhood (PPAC) is a disorder of bone and cartilage that affects many joints. Major signs and symptoms include stiff joints (contractures), short stature, and widening of the ends of the finger and toe bones as well as other tubular bones. PPAC may initially be mistaken for juvenile rheumatoid arthritis, however people with this condition do not have the laboratory test results of juvenile rheumatoid arthritis. PPAC is caused by a mutation in the WISP3 gene and is inherited in an autosomal recessive pattern. People with PPAC typically need joint replacement surgery at an early age. Other forms of spondyloepiphyseal dysplasia tarda include: X-linked spondyloepiphyseal dysplasia tarda  Autosomal dominant spondyloepiphyseal dysplasia tarda  Spondyloepiphyseal dysplasia tarda Toledo type
Question: What is (are) Factor XI deficiency ?

Answer: Factor XI deficiency is a bleeding disorder that interferes with the body's clotting process. As a result, people affected by this condition may have difficulty stopping the flow of blood following dental extractions, trauma or surgery. Women with factor XI deficiency may also experience heavy menstrual periods or heavy postpartum bleeding. Within affected people and their families, highly variable bleeding patterns occur, and bleeding risk can not be predicted by the level of factor XI (a clotting factor) in the blood. Although the condition can affect people of all heritages, it is most common in people of Ashkenazi Jewish descent. Most cases of factor XI deficiency are inherited and caused by changes (mutations) in the F11 gene. The condition is generally inherited in an autosomal recessive manner; however, it may follow an autosomal dominant pattern in some families. Treatment is often only recommended during periods of high bleeding risk (i.e. surgery) and may include fresh frozen plasma and/or antifibrinolytics (medications that improve blood clotting). Factor XI concentrates may be available for factor replacement in some countries.
Question: What is (are) Familial esophageal achalasia ?

Answer: Familial esophageal achalasia refers to a cluster of achalasia within a family. Achalasia is a condition that affects the esophagus, the tube that carries food from the mouth to the stomach. In people with achalasia, the normal muscle activity of the esophagus is reduced and the muscular valve where the esophagus and the stomach meet doesn't fully relax. This makes it difficult for food to move from the esophagus to the stomach. As a result, people with achalasia may experience regurgitation of food, chest pain, cough, difficulty swallowing, heartburn, and/or unintentional weight loss. Reports of familial esophageal achalasia are rare and represent less than 1% of all achalasia cases. In these families, the underlying genetic cause of the condition is unknown, but it appears to be inherited in an autosomal recessive manner. Treatment aims to allow food to pass more easily into this stomach and may include injections with botulinum toxin (Botox), certain medications and/or surgery.
Question: What is (are) Hypophosphatemic rickets ?

Answer: Hypophosphatemic rickets (previously called vitamin D-resistant rickets) is a disorder in which the bones become painfully soft and bend easily, due to low levels of phosphate in the blood. Symptoms usually begin in early childhood and can range in severity. Severe forms may cause bowing of the legs and other bone deformities; bone pain; joint pain; poor bone growth; and short stature. In some affected babies, the space between the skull bones closes too soon (craniosynostosis). This sometimes results in developmental abnormalities. Hypophosphatemic rickets is almost always inherited and may be caused by changes (mutations) in any of several genes. Most commonly it is due to the PHEX gene and inherited in an X-linked dominant manner. Less commonly it is inherited in an X-linked recessive manner (often called Dent disease); autosomal dominant manner; or autosomal recessive manner. Treatment involves taking phosphate and calcitriol in order to raise phosphate levels in the blood and promote normal bone formation.
Question: Is Ehlers-Danlos syndrome, progeroid type inherited ?

Answer: How is Ehlers-Danlos syndrome progeroid type inherited? Ehlers-Danlos syndrome progeroid type is inherited in an autosomal recessive pattern. This means that an individual must have two non-functional copies of the B4GALT7 gene to be affected with the condition. One copy is inherited from each parent. If an individual has only one non-functional B4GALT7 gene (such as each parent), he or she is a "carrier". Carriers do not typically show any signs or symptoms of a recessive condition. When two carriers for a recessive condition have children, with each pregnancy there is a 25% (1 in 4) risk for the child to be affected, a 50%  (1 in 2) risk for the child to be a carrier (like each parent) and a 25% risk that the child will be unaffected and also not be a carrier. An individual with a recessive condition will generally have unaffected children, except in the rare circumstance where his or her partner is a carrier of a nonfunctional B4GALT7 gene.
Question: What are the treatments for Ovarian carcinosarcoma ?

Answer: How might ovarian carcinosarcoma be treated? Because ovarian carcinosarcoma is rare, there are no established treatment guidelines.  Treatment decisions are based on the unique features of each individual's diagnosis.  The National Comprehensive Cancer Network (NCCN), a group of physicians and researchers who strive to improve cancer care, recommends that women with ovarian carcinosarcoma be treated similarly to women with ovarian carcinoma (also called epithelial ovarian cancer), which is the most common type of ovarian cancer. Currently, treatment for ovarian carcinosarcoma usually begins with surgery to remove as much of the cancer as possible.  Chemotherapy may be used to destroy any cancer cells that could be in the body after surgery.  Medications that contain platinum (such as the drug cisplatin) seem to be the most effective chemotherapies for ovarian carcinosarcoma.  Recent evidence suggests that another medication called ifosfamide may increase the effectiveness of treatment when used in combination with platinum-based medications.
Question: What causes Charcot-Marie-Tooth disease type 2F ?

Answer: What causes Charcot-Marie-Tooth disease type 2F? Charcot-Marie-Tooth disease type 2F (CMT2F) is caused by mutations in the HSPB1 gene. This gene provides instructions for making a protein (heat shock protein beta-1) which helps protect cells under adverse conditions. Heat shock proteins appear to be involved in activities such as cell movement, stabilizing the cell's framework, folding and stabilizing new proteins, repairing damaged proteins, and muscle contraction. Heat shock protein beta-1 is particularly abundant in nerve and muscle cells. In nerve cells, it helps to organize a network of threads that maintain the diameter of axons (neurofilaments), which are needed to transmit nerve impulses efficiently. It is unclear exactly how HSPB1 mutations lead to the axon abnormalities characteristic of CMT2F. Researchers suggest that mutations lead to an altered protein which clusters together and interferes with nerve cell function. Another possibility is that the altered protein disrupts the assembly of neurofilaments, which in turn may impair the transmission of nerve impulses.
Question: what research (or clinical trials) is being done for Migraine ?

Answer: Researchers believe that migraine is the result of fundamental neurological abnormalities caused by genetic mutations at work in the brain. New models are aiding scientists in studying the basic science involved in the biological cascade, genetic components and mechanisms of migraine. Understanding the causes of migraine as well as the events that effect them will give researchers the opportunity to develop and test drugs that could be more targeted to preventing or interrupting attacks entirely. Therapies currently being tested for their effectiveness in treating migraine include magnesium, coenzyme Q10, vitamin B12, riboflavin, fever-few, and butterbur. 
                
In 2010, a team of researchers found a common mutation in the gene TRESK which contains instructions for a certain potassium ion channel. Potassium channels are important for keeping a nerve cell at rest and mutations in them can lead to overactive cells that respond to much lower levels of pain. Large genetic analyses similar to the one used to identify TRESK will most likely lead to the identification of a number of other genes linked to migraine.
Question: What is (are) Tarlov Cysts ?

Answer: Tarlov cysts are sacs filled with cerebrospinal fluid that most often affect nerve roots in the sacrum, the group of bones at the base of the spine. These cysts (also known as meningeal or perineural cysts) can compress nerve roots, causing lower back pain, sciatica (shock-like or burning pain in the lower back, buttocks, and down one leg to below the knee), urinary incontinence, headaches (due to changes in cerebrospinal fluid pressure), constipation, sexual dysfunction, and some loss of feeling or control of movement in the leg and/or foot. Pressure on the nerves next to the cysts can also cause pain and deterioration of surrounding bone. Tarlov cysts can be diagnosed using magnetic resonance imaging (MRI); however, it is estimated that the majority of the cysts observed by MRI cause no symptoms. Tarlov cysts may become symptomatic following shock, trauma, or exertion that causes the buildup of cerebrospinal fluid. Women are at much higher risk of developing these cysts than are men.
Question: Is Pallister-Killian mosaic syndrome inherited ?

Answer: Pallister-Killian mosaic syndrome is not inherited. The chromosomal change responsible for the disorder typically occurs as a random event during the formation of reproductive cells (eggs or sperm) in a parent of the affected individual, usually the mother. Affected individuals have no history of the disorder in their families.  An error in cell division called nondisjunction likely results in a reproductive cell containing an isochromosome 12p. If this atypical reproductive cell contributes to the genetic makeup of a child, the child will have two normal copies of chromosome 12 along with an isochromosome 12p.  As cells divide during early development, some cells lose the isochromosome 12p, while other cells retain the abnormal chromosome. This situation is called mosaicism. Almost all cases of Pallister-Killian mosaic syndrome are caused by mosaicism for an isochromosome 12p. If all of the body's cells contained the isochromosome, the resulting syndrome would probably not be compatible with life.
Question: What are the genetic changes related to head and neck squamous cell carcinoma ?

Answer: HNSCC is caused by a variety of factors that can alter the DNA in cells. The strongest risk factors for developing this form of cancer are tobacco use (including smoking or using chewing tobacco) and heavy alcohol consumption. In addition, studies have shown that infection with certain strains of human papillomavirus (HPV) is linked to the development of HNSCC. HPV infection accounts for the increasing incidence of HNSCC in younger people.  Researchers have identified mutations in many genes in people with HNSCC; however, it is not yet clear what role most of these mutations play in the development or progression of cancer. The proteins produced from several of the genes associated with HNSCC, including TP53, NOTCH1, and CDKN2A, function as tumor suppressors, which means they normally keep cells from growing and dividing too rapidly or in an uncontrolled way. When tumor suppressors are impaired, cells can grow and divide without control, leading to tumor formation. It is likely that a series of changes in multiple genes is involved in the development and progression of HNSCC.
Question: What are the genetic changes related to genitopatellar syndrome ?

Answer: Genitopatellar syndrome is caused by mutations in the KAT6B gene. This gene provides instructions for making a type of enzyme called a histone acetyltransferase. These enzymes modify histones, which are structural proteins that attach (bind) to DNA and give chromosomes their shape. By adding a small molecule called an acetyl group to histones, histone acetyltransferases control the activity of certain genes. Little is known about the function of the histone acetyltransferase produced from the KAT6B gene. It appears to regulate genes that are important for early development, including development of the skeleton and nervous system.  The mutations that cause genitopatellar syndrome occur near the end of the KAT6B gene and lead to the production of a shortened histone acetyltransferase enzyme. Researchers suspect that the shortened enzyme may function differently than the full-length version, altering the regulation of various genes during early development. However, it is unclear how these changes lead to the specific features of genitopatellar syndrome.
Question: What are the genetic changes related to glycine encephalopathy ?

Answer: Mutations in the AMT and GLDC genes cause glycine encephalopathy.  About 80 percent of cases of glycine encephalopathy result from mutations in the GLDC gene, while AMT mutations cause 10 percent to 15 percent of all cases. In a small percentage of affected individuals, the cause of this condition is unknown.  The AMT and GLDC genes provide instructions for making proteins that work together as part of a larger enzyme complex. This complex, known as glycine cleavage enzyme, is responsible for breaking down glycine into smaller pieces. Mutations in either the AMT or GLDC gene prevent the complex from breaking down glycine properly. When glycine cleavage enzyme is defective, excess glycine can build up to toxic levels in the body's organs and tissues. Damage caused by harmful amounts of this molecule in the brain and spinal cord is responsible for the intellectual disability, seizures, and breathing difficulties characteristic of glycine encephalopathy.
Question: What is (are) carnitine-acylcarnitine translocase deficiency ?

Answer: Carnitine-acylcarnitine translocase (CACT) deficiency is a condition that prevents the body from using certain fats for energy, particularly during periods without food (fasting). Signs and symptoms of this disorder usually begin soon after birth and may include breathing problems, seizures, and an irregular heartbeat (arrhythmia). Affected individuals typically have low blood sugar (hypoglycemia) and a low level of ketones, which are produced during the breakdown of fats and used for energy. Together these signs are called hypoketotic hypoglycemia. People with CACT deficiency also usually have excess ammonia in the blood (hyperammonemia), an enlarged liver (hepatomegaly), and a weakened heart muscle (cardiomyopathy).  Many infants with CACT deficiency do not survive the newborn period. Some affected individuals have a less severe form of the condition and do not develop signs and symptoms until early childhood. These individuals are at risk for liver failure, nervous system damage, coma, and sudden death.
Question: What are the genetic changes related to Smith-Magenis syndrome ?

Answer: Most people with Smith-Magenis syndrome have a deletion of genetic material from a specific region of chromosome 17. Although this region contains multiple genes, researchers believe that the loss of one particular gene, RAI1, in each cell is responsible for most of the characteristic features of this condition. The loss of other genes in the deleted region may help explain why the features of Smith-Magenis syndrome vary among affected individuals.  A small percentage of people with Smith-Magenis syndrome have a mutation in the RAI1 gene instead of a chromosomal deletion. Although these individuals have many of the major features of the condition, they are less likely than people with a chromosomal deletion to have short stature, hearing loss, and heart or kidney abnormalities.  The RAI1 gene provides instructions for making a protein whose function is unknown. Mutations in one copy of this gene lead to the production of a nonfunctional version of the RAI1 protein or reduce the amount of this protein that is produced in cells. Researchers are uncertain how changes in this protein result in the physical, mental, and behavioral problems associated with Smith-Magenis syndrome.
Question: What are the genetic changes related to geleophysic dysplasia ?

Answer: Geleophysic dysplasia results from mutations in the ADAMTSL2 gene. This gene provides instructions for making a protein whose function is unclear. The protein is found in the extracellular matrix, which is the intricate lattice of proteins and other molecules that forms in the spaces between cells. Studies suggest that the ADAMTSL2 protein may play a role in the microfibrillar network, which is an organized clustering of thread-like filaments (called microfibrils) in the extracellular matrix. This network provides strength and flexibility to tissues throughout the body.  Mutations in the ADAMTSL2 protein likely change the protein's 3-dimensional structure. Through a process that is poorly understood, ADAMTSL2 gene mutations alter the microfibrillar network in many different tissues. Impairment of this essential network disrupts the normal functions of cells, which likely contributes to the varied signs and symptoms of geleophysic dysplasia. Researchers are working to determine how mutations in the ADAMTSL2 gene lead to short stature, heart disease, and the other features of this condition.
Question: What are the symptoms of Urinary Retention ?

Answer: The symptoms of acute urinary retention may include the following and require immediate medical attention:
                
- inability to urinate  - painful, urgent need to urinate  - pain or discomfort in the lower abdomen  - bloating of the lower abdomen
                
The symptoms of chronic urinary retention may include
                
- urinary frequencyurination eight or more times a day  - trouble beginning a urine stream  - a weak or an interrupted urine stream  - an urgent need to urinate with little success when trying to urinate  - feeling the need to urinate after finishing urination  - mild and constant discomfort in the lower abdomen and urinary tract
                
Some people with chronic urinary retention may not have symptoms that lead them to seek medical care. People who are unaware they have chronic urinary retention may have a higher chance of developing complications.
                

                
When to Seek Medical Care   A person who has any of the following symptoms should see a health care provider right away:   - complete inability to urinate   - great discomfort or pain in the lower abdomen and urinary tract
Question: What is (are) Polycythemia Vera ?

Answer: Key Points
                    - Polycythemia vera is a disease in which too many red blood cells are made in the bone marrow.    - Symptoms of polycythemia vera include headaches and a feeling of fullness below the ribs on the left side.    - Special blood tests are used to diagnose polycythemia vera.
                
                
                    Polycythemia vera is a disease in which too many red blood cells are made in the bone marrow.
                    In polycythemia vera, the blood becomes thickened with too many red blood cells. The number of white blood cells and platelets may also increase. These extra blood cells may collect in the spleen and cause it to swell. The increased number of red blood cells, white blood cells, or platelets in the blood can cause bleeding problems and make clots form in blood vessels. This can increase the risk of stroke or heart attack. In patients who are older than 65 years or who have a history of blood clots, the risk of stroke or heart attack is higher. Patients also have an increased risk of acute myeloid leukemia or primary myelofibrosis.
Question: What is (are) Diphtheria ?

Answer: Diphtheria is a serious bacterial infection. You can catch it from a person who has the infection and coughs or sneezes. You can also get infected by coming in contact with an object, such as a toy, that has bacteria on it.    Diphtheria usually affects the nose and throat. Symptoms include       - Sore throat    - Swollen glands in the neck    - Fever    - Weakness       Your doctor will diagnose it based on your signs and symptoms and a lab test. Getting treatment for diphtheria quickly is important. If your doctor suspects that you have it, you'll start treatment before the lab tests come back. Treatment is with antibiotics.    The diphtheria, pertussis, and tetanus vaccine can prevent diphtheria, but its protection does not last forever. Children need another dose, or booster, at about age 12. Then, as adults, they should get a booster every 10 years. Diphtheria is very rare in the United States because of the vaccine.    Centers for Disease Control and Prevention
Question: What is (are) Turner Syndrome ?

Answer: Turner syndrome is a genetic disorder that affects a girl's development. The cause is a missing or incomplete X chromosome. Girls who have it are short, and their ovaries don't work properly.    Other physical features typical of Turner syndrome are       -  Short, "webbed" neck with folds of skin from tops of shoulders to sides of neck    -  Low hairline in the back    -  Low-set ears    -  Swollen hands and feet       Most women with Turner syndrome are infertile. They are at risk for health difficulties such as high blood pressure, kidney problems, diabetes, cataracts, osteoporosis, and thyroid problems.    Doctors diagnose Turner syndrome based on symptoms and a genetic test. Sometimes it is found in prenatal testing. There is no cure for Turner syndrome, but there are some treatments for the symptoms. Growth hormone often helps girls reach heights that are close to average. Hormone replacement can help start sexual development. Assisted reproduction techniques can help some women with Turner syndrome get pregnant.    NIH: National Institute of Child Health and Human Development
