Question: What are the symptoms of Huntington disease ?
Answer: What are the signs and symptoms of Huntington disease? Huntington disease (HD) is a progressive disorder that causes motor, cognitive, and psychiatric signs and symptoms. On average, most people begin developing features of HD between ages 35 and 44. Signs and symptoms vary by stage and may include: Early stage: Behavioral disturbances Clumsiness Moodiness Irritability Paranoia Apathy Anxiety Hallucinations Abnormal eye movements Depression Impaired ability to detect odors Middle stage: Dystonia Involuntary movements Trouble with balance and walking Chorea with twisting and writhing motions Unsteady gait (style of walking) Slow reaction time General weakness Weight loss Speech difficulties Stubbornness Late stage: Rigidity (continual tension of the muscles) Bradykinesia (difficulty initiating and continuing movements) Severe chorea Serious weight loss Inability to speak Inability to walk Swallowing problems Inability to care for oneself There is also a less common, early-onset form of HD which begins in childhood or adolescence. For more information on this form, please visit GARD's juvenile Huntington disease Web page. The Human Phenotype Ontology provides the following list of signs and symptoms for Huntington disease. 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 movement 50% Abnormality of the voice 50% Behavioral abnormality 50% Cerebral cortical atrophy 50% Developmental regression 50% EEG abnormality 50% Hypertonia 50% Rigidity 7.5% Abnormality of eye movement - Autosomal dominant inheritance - Bradykinesia - Chorea - Dementia - Depression - Gliosis - Hyperreflexia - Neuronal loss in central nervous system - Personality changes - 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.

Question: What causes Huntington disease ?
Answer: What causes Huntington disease? Huntington disease (HD) is caused by a change (mutation) in the HTT gene. This gene gives instructions for making a protein called huntingtin. The exact function of this protein is unclear, but it appears to be important to nerve cells (neurons) in the brain. The HTT gene mutation that causes HD involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of three DNA building blocks that repeat multiple times in a row. The CAG segment in a normal HTT gene repeats about 10 to 35 times. In people with HD, it may repeat from 36 to over 120 times. People with 36 to 39 CAG repeats (an intermediate size) may or may not develop HD, while people with 40 or more repeats almost always develop HD. An increased number of CAG repeats leads to an abnormally long version of the huntingtin protein. The long protein is then cut into smaller, toxic pieces that end up sticking together and accumulating in neurons. This disrupts the function of the neurons, ultimately causing the features of HD.

Question: Is Huntington disease inherited ?
Answer: How is Huntington disease inherited? Huntington disease (HD) is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one of the 2 copies of the HTT gene is enough to cause the condition. When a person with HD has children, each child has a 50% (1 in 2) chance to inherit the mutated gene and develop the condition. Most people with HD have an affected parent. The family history can sometimes appear negative for various reasons even though a parent carries, or carried, a mutation in the HTT gene. In rare cases, HD is caused by a new (de novo) mutation in the HTT gene, in which case the disease occurs for the first time in the affected person and is not inherited from a parent. As HD is passed through generations, the size of the mutation in the HTT gene (called a trinucleotide repeat) often increases. A longer repeat in the HTT gene may cause earlier onset of symptoms. This phenomenon is called anticipation.

Question: How to diagnose Huntington disease ?
Answer: Is genetic testing available for Huntington disease? Yes. Testing of adults at risk for Huntington disease (HD) who have no symptoms of the disease is called predictive testing. Whether to have predictive testing requires careful thought, including pre-test and post-test genetic counseling. This is particularly important because there is currently no cure. Furthermore, predictive testing cannot accurately predict the age a person with an HD mutation will develop symptoms, the severity or type of symptoms they will experience, or the future rate of disease progression. A person may want to have predictive testing because they feel they need to know, or to make personal decisions involving having children, finances, and/or career planning. Other people decide they do not want to know whether they will develop HD. Testing is appropriate to consider in symptomatic people of any age in a family with a confirmed diagnosis of HD. However, testing of asymptomatic people younger than age 18 is not considered appropriate. A main reason is that it takes away the choice of whether the person wants to know, while there is no major benefit to knowing at that age. People who are interested in learning more about genetic testing for HD should speak with a genetics professional. How is Huntington disease diagnosed? A diagnosis of Huntington disease is typically suspected in people with characteristic signs and symptoms of the condition and a family history consistent with autosomal dominant inheritance. The diagnosis can then be confirmed with genetic testing that identifies a specific type of change (mutation) in the HTT gene.

Question: What are the treatments for Huntington disease ?
Answer: How might Huntington disease be treated? Unfortunately, there is currently no cure for Huntington disease (HD). The current goal of treatment is to slow down the course of the disease and help affected people function for as long and as comfortably as possible. Current treatment strategies involve the use of various medications to treat specific symptoms such as abnormal movements and behaviors. Depression and suicide are more common among affected people, so caregivers should monitor for associated symptoms and seek help if necessary. As symptoms of the disease worsen, affected people need more assistance, supervision, and care.

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) Hypoplastic right heart syndrome ?
Answer: Hypoplastic right heart syndrome is a rare heart defect, present at birth (congenital), that results in low blood oxygen levels. It is caused by underdevelopment of the structures on the right side of the heart (tricuspid valve, right ventricle, pulmonary valve, and pulmonary artery) and commonly associated with atrial septal defect. The underdeveloped right side of the heart is unable to provide enough blood flow to the body, leading to low blood oxygen and cyanosis. It differs from hypoplastic left heart syndrome which involves the underdevelopment of the structures on the left side of the heart.

Question: What is (are) Brittle cornea syndrome ?
Answer: Brittle cornea syndrome (BCS) is a type of connective tissue disorder that mainly affects the eyes, joints and skin. Signs and symptoms may include rupture of the cornea after only minor trauma; degeneration of the cornea (keratoconus) or thinning and protrusion of the cornea (keratoglobus); bluish tint in the white part of the eyes (blue sclerae); hypermobile joints; hyperelastic skin; hearing defects; and dental abnormalities. There are 2 types of BCS which are distinguished by the mutated gene that causes the condition. BCS type 1 is caused by mutations in the ZNF469 gene and BCS type 2 is caused by mutations in the PRDM5 gene. BCS is inherited in an autosomal recessive manner.
