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
Autosomal dominant genetic disorder?
An autosomal genetic disorder is Huntington's disease.
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 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.
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.
Is Huntingtons disease a hereditary bleeding disorder passed from mother to child?
No. While it is a hereditary disease it is not at all a bleeding disorder, nor is it only passed by the mother. It is a degenerative, neuropsychiatric disease that can be passed by either the mother or father. If the parent has it, the child's chance of inheritance is of the faulty gene is 50%.
Who found the gene for huntingtons disease?
The hunt for the gene was accomplished by the work of many dedicated researchers working cooperatively.
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.
Is Huntington's Disease a gene mutation?
No, it's caused by a single point mutation of a gene.
Is huntington's disease determined by multiple alleles?
No. This is a single gene disorder. If at least one allele has the huntington's mutation, the person will eventually develop the disease.
What gene does bipolar disorder happen in?
There is not a single gene responsible for bipolar disorder that has been identified.
What is a Co-dominant alleles disorder?
One example is Huntington's Disease. With a recessive genetic disorder, to develop the disorder, you must inherit the gene from BOTH parents (odds, 1 in 4). With a dominant gene disorder, if you inherit the gene from ONE parent, you will develop that disorder (odds- 1 in 2).
