Question:  Is Hydrocephalus due to congenital stenosis of aqueduct of sylvius inherited ?
Answer: Is hydrocephalus due to congenital stenosis of aqueduct of sylvius inherited? Hydrocephalus due to congenital stenosis of aqueduct of sylvius is inherited in an X-linked recessive manner. A condition is X-linked if the responsible gene is located on the X chromosome. The X chromosome is one of the two sex chromosomes (the other sex chromosome is the Y chromosome). Females have two X chromosomes in each cell and males have an X chromosome and a Y chromosome in each cell. Although females have two X chromosomes, one of the X chromosomes in each cell is "turned off" and all of the genes on that chromosome are inactivated. Females who have a change (mutation) in a gene on one of their X chromosomes are called carriers of the related condition. Carrier females usually do not have symptoms of the condition because the X chromosome with the mutated gene is often turned off and they have another X chromosome with a working copy of the gene. Sometimes, the X chromosome with the working copy of the gene is turned off, which may cause symptoms of the condition. However, females with symptoms are usually much more mildly affected than males. A male has only one X chromosome, so if he inherits a mutation on the X chromosome, he will have signs and symptoms (be affected). Males with an X-linked recessive condition always pass the mutated gene to all of their daughters, who will be carriers. A male cannot pass an X-linked gene to his sons because males always pass their Y chromosome to male offspring. Female carriers of an X-linked recessive condition have a 25% chance with each pregnancy to have a carrier daughter like themselves, a 25% chance to have a non-carrier daughter, a 25% chance to have an affected son, and a 25% chance to have an unaffected son. This also means that each daughter of a carrier mother has a 50% chance of being a carrier, and each son has a 50% chance of having the condition.
Question:  How to diagnose Hydrocephalus due to congenital stenosis of aqueduct of sylvius ?
Answer: How is hydrocephalus due to congenital stenosis of aqueduct of sylvius diagnosed? A diagnosis of hydrocephalus due to congenital stenosis of aqueduct of sylvius is typically suspected based on the presence of characteristic signs and symptoms on physical examination and/or brain imaging (i.e. CT scan, MRI scan). Identification of a change (mutation) in the L1CAM gene can be used to confirm the diagnosis.
Question:  What are the treatments for Hydrocephalus due to congenital stenosis of aqueduct of sylvius ?
Answer: How might hydrocephalus due to congenital stenosis of aqueduct of sylvius be treated? The treatment of hydrocephalus due to congenital stenosis of aqueduct of sylvius (HSAS) is based on the signs and symptoms present in each person. For example, hydrocephalus is typically treated with shunt surgery. Special education and early intervention may be recommended for children with intellectual disability. Although intervention is rarely necessary for adducted thumbs (bent towards the palms), tendon transfer surgery or splinting may be suggested in some cases.

Question:  What is (are) Fanconi Bickel syndrome ?
Answer: Fanconi Bickel syndrome (FBS) is a rare glycogen storage disease characterized by glycogen accumulation in the liver and kidneys; severe renal tubular dysfunction; and impaired glucose and galactose metabolism. Signs and symptoms begin in the first few months of life and include failure to thrive, excessive urination (polyuria) and rickets, followed by short stature and hepatosplenomegaly in early childhood. Puberty is delayed. FBS is inherited in an autosomal recessive manner and is caused by mutations in the SLC2A2 gene. Treatment is generally symptomatic.

Question:  What are the treatments for Fanconi Bickel syndrome ?
Answer: How might Fanconi Bickel syndrome be treated? Management of Fanconi Bickel syndrome (FBS) generally focuses on the signs and symptoms of the condition. Treatment includes replacement of water and electrolytes, and vitamin D and phosphate supplements for prevention of hypophosphatemic rickets. Although there is limited data on the effectiveness of dietary treatment for this condition, it is recommended that affected individuals follow a galactose-restricted diabetic diet, with fructose as the main source of carbohydrate. Diet and supplements may alleviate some of the signs and symptoms of the condition but generally do not improve growth, resulting in short stature in adulthood.
Question:  What is (are) Down syndrome ?
Answer: Down syndrome is a chromosome disorder associated with intellectual disability, a characteristic facial appearance, and low muscle tone in infancy. The degree of intellectual disability varies from mild to moderate. People with Down syndrome may also be born with various health concerns such as heart defects or digestive abnormalities. They also have an increased risk to develop gastroesophageal reflux, celiac disease, hypothyroidism, hearing and vision problems, leukemia, and Alzheimer disease. Down syndrome is caused by having three copies of chromosome 21 (called trisomy 21) instead of the usual two copies and is typically not inherited. Treatment focuses on the specific symptoms in each person.
Question:  What causes Down syndrome ?
Answer: What causes Down syndrome? There are 3 possible genetic causes of Down syndrome: Trisomy 21. Most often, Down syndrome is caused by an extra chromosome 21 in all cells of the affected person.  In these cases, the chromosome 21 pair fails to separate during the formation of an egg (or sperm); this is called "nondisjunction." When the egg with 2 copies of chromosome 21 unites with a normal sperm with one copy of chromosome 21 to form an embryo, the resulting embryo has 3 copies of chromosome 21 instead of the normal two. The extra chromosome is then copied in every cell of the baby's body, causing the features of Down syndrome. The cause of nondisjunction is unknown, but research has shown that it happens more often as women age. Nondisjunction is not known to be caused by anything in the environment or anything that parents do (or don't do) before or during pregnancy. Mosaic trisomy 21. In about 1-2% of cases, only some of the cells in a person's body have an extra chromosome 21; this is called "mosaic trisomy 21".  In this situation, the fertilized egg may have the right number of chromosomes, but due to a cell division error early in the development of the embryo, some cells "acquire" an extra chromosome 21. A person with mosaic trisomy 21 typically has 46 chromosomes in some cells, and 47 chromosomes (with the extra chromosome 21) in others. The features and severity in people with mosaic trisomy 21 may vary widely.  Translocation trisomy 21. About 3-4% of people with Down syndrome have cells that contain 46 chromosomes; however, there is extra chromosome 21 material attached (translocated ) onto another chromosome.  For parents of a child with Down syndrome due to a translocation, there may be an increased chance of Down syndrome in future pregnancies. This is because one of the two parents may be a carrier of a balanced translocation. However, not all parents of people with translocation trisomy 21 have a translocation. Regardless of the type of Down syndrome a person has, all people with Down syndrome have an extra, critical portion of chromosome 21 present in all or some of their cells. This extra genetic material disrupts the normal course of development, causing the characteristic features of Down syndrome.
Question:  How to diagnose Down syndrome ?
Answer: How is Down syndrome diagnosed? Down syndrome may be suspected and/or diagnosed during pregnancy, or after a child is born. During pregnancy, a woman can opt to have specific tests that may either screen for, or diagnosis, Down syndrome in a fetus. A screening test poses no risks to the fetus and can determine the likelihood that a fetus has Down syndrome. It may show that a fetus is at an increased risk to be affected, but cannot determine whether it is definitely affected. Screening tests for Down syndrome may involve different types of blood tests for the mother and/or specific types of ultrasounds that can detect features more common in fetuses with Down syndrome (called markers). Depending on the type of screening tests a woman has, they may be done during the 1st trimester, the 2nd trimester, or both. If a screening test shows an increased risk for Down syndrome, a woman may then choose to have a diagnostic test. Diagnostic tests during pregnancy can determine with certainty whether a fetus has Down syndrome, but they are invasive and carry a slight risk of miscarriage. Examples of diagnostic tests include chorionic villus sampling in the 1st trimester and amniocentesis in the 2nd trimester. During these tests, a small sample of genetic material is obtained from the amniotic fluid or placenta, and the fetus' chromosomes are then analyzed in a laboratory. In recent years, non-invasive prenatal testing (NIPT) has become available to women who are at increased risk to have a baby with Down syndrome. NIPT is a blood test that examines DNA from the fetus in the mother's bloodstream. However, women who have a positive NIPT result should then have invasive diagnostic testing to confirm the result. People with questions about the different options for prenatal screening or diagnostic testing should speak with a genetic counselor. A genetic counselor can discuss the benefits, limitations and risks of each test, and help each person decide which test (if any) is best for them. If a diagnosis of Down syndrome is not made prenatally, the diagnosis can be made in the newborn. Down syndrome may be suspected if a newborn has characteristic physical features of the condition. The diagnosis can then be confirmed by obtaining a karyotype (a blood test to look at a picture of the newborn's chromosomes).
Question:  What are the treatments for Down syndrome ?
Answer: How might Down syndrome be treated? Early intervention services, quality educational programs, a stimulating home environment, good health care, and positive support from family and friends can help people with Down syndrome develop to their full potential. The overall goal of treatment is to boost cognition by improving learning, memory, and speech. Other treatments depend on the specific health problems or complications present in each affected person. The Research Down syndrome Foundation have a webpage with information about active reseach projects.

Question:  What is (are) Churg Strauss syndrome ?
Answer: Churg Strauss syndrome is a condition characterized by asthma, high levels of eosinophils (a type of white blood cell that helps fight infection), and inflammation of small to medium sized blood vessels (vasculitis). The inflamed vessels can affect various organ systems including the lungs, gastrointestinal tract, skin, heart and nervous system. The exact cause of Churg Strauss syndrome is unknown, but it is thought to be an autoimmune disorder. Treatment may involve the use of glucocorticoids and/or other immunosuppressive therapies.
Question:  What is (are) Lennox-Gastaut syndrome ?
Answer: Lennox-Gastaut syndrome is a form of severe epilepsy that begins in childhood. It is characterized by multiple types of seizures and intellectual disability. This condition can be caused by brain malformations, perinatal asphyxia (lack of oxygen), severe head injury, central nervous system infection and inherited degenerative or metabolic conditions. In about one-third of cases, no cause can be found. Treatment for Lennox-Gastaut syndrome includes anti-epileptic medications such as valproate, lamotrigine, felbamate, or topiramate. There is usually no single antiepileptic medication that will control seizures. Children may improve initially, but many later show tolerance to a drug or develop uncontrollable seizures.
