A member asked:
Is it possible for a person to have two dominate alleles for huntingtons?
A doctor has provided 1 answer
Yes: It's very unusual for someone to inherit two mutations - one for each of their huntington disease genes, but it's possible. A person with homozygosity will develop the signs and symptoms of hd at about the same age, on average, as someone with just one mutation. However, the disease progresses more rapidly.
