What genetic test is carried out for confirmation of Huntington disease?
a small blood sample is taken, and DNA from it is analyzed to determine the CAG repeat number. A person with a repeat number of 30 or below will not develop HD.
Is Huntington's disease a point mutation?
No, it is caused by extra repetitions of a CAG (cytosine-adenine-guanine) codon repeat stretch within the Huntingtin gene.
Is Huntington's disease an example of polygenic inheritance?
No.It is caused by versions of a single gene on the short arm of chromosome 4. This gene contains a region in which the bases CAG repeat. In people without the disease, there may be about 11 to 34 repeats; if there are more than about 42 in either copy of the gene, Huntington's disease will set in. The more repeats, the earlier the onset.
What is the frequency of the mutation genetic disease of the huntington disease?
Hungtington disease is a trinucleotide repeat genetic disorder, in which you have extra repeats of CAG in your gene coding for the hungtin protein. If you have more than 35 repeats you get the phenotype (symptoms), and it shows anticipation, which means that as the disease is passed on from generation to generation the repeats increase, hence the severity of the disease. It is quite rare, but the exact incidence is hard to estimate, because people carrying 30 repeats are asymptomatic. Hope this helps
What is the mutated allele that causes huntington's disease?
Autosomal and dominant. It's a defective gene on chromosome 4. :D Hope this helps!
