Is huntingtons a chromosomal or a genetic disease?
Hungtington's disease is a dominant mutation in the gene that codes for the protein 'Huntington' It only affects a single gene, the remainder of the chromosome is unaffected and therefore it is not a chromosomal abnormality
What is the percentage of people that get huntingtons disease?
Around 1 in 10,000 people are estimated to develop Huntington's disease, a rare genetic disorder. It is caused by a mutation in the HTT gene on chromosome 4.
What age do you get huntingtons disease?
For a person with the Huntingtons gene the first symptoms usually strike in late middle age at around 50-55. There are people however with the gene who have had first symptoms in their late 80s and some in their early 20s. You have to have the gene to get the disease.
Who found the gene for huntingtons disease?
The hunt for the gene was accomplished by the work of many dedicated researchers working cooperatively.
Is huntington's disease a mutation?
No, it is a dominant gene
What is the type of mutation that causes crohn's disease?
A frameshift mutation in the CARD15 gene
Why is huntingtons disease more common than other serious dominant genetic disorders?
Huntingtons is a genetically inherited disease from a parent. when chromosomes are passed onto a child, the child wont always receive the chromosome containing the gene. But, if they do inherit the gene they will have the disease no matter what, because the disease is dominant. If it was recessive, the child could inherit the disease but not necessarily get the disease.
What disease can a gene mutation cause?
usually cancer
What causes huningtons disease?
Huntingtons disease is a genetic/inherited diesease. It is caused by a faulty allele (a dominant one), which can be inherited by parents. Spontanoius mutations may also occur which would cause the faulty gene and therefore huntingtons disorder.
What disease that is called by a mutation in the gene that codes for somatostatin?
Autism Dwarfism
What is a human genetic disorder caused by a dominant gene is?
One example is Huntington's Disease. Carried on a dominant gene, it causes deterioration of the central nervous system, affecting movement, swallowing, personality, etc.
Compare the inheritance of Huntingtons disease with the inheritance of sickle cell anemia?
Huntingtons disease is Autosomal dominant, i.e. a 50% chance of inheritance if one parent has the gene. Where as sickle cell anemia is autosomal recessive. This gives a 25% chance of inheritance if both parents are carriers.
