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.
The genetic test for Huntington's disease is commonly referred to as the "Huntington's disease genetic test" or "HTT gene testing." This test analyzes the CAG repeat expansion in the HTT gene on chromosome 4. If you're discussing this with your doctor, you can simply refer to it as the Huntington's disease genetic test, and they will know how to proceed with the ordering process.
No, it is caused by extra repetitions of a CAG (cytosine-adenine-guanine) codon repeat stretch within the Huntingtin gene.
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.
Autosomal and dominant. It's a defective gene on chromosome 4. :D Hope this helps!

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
