How many and what type of people are likely to have the disorder Huntington disease?

Huntington's disease primarily affects adults aged 30 to 50, with symptoms typically appearing in mid-adulthood. It is an inherited genetic disorder caused by a mutation in the HTT gene, meaning that individuals with a family history of the disease are at higher risk. Both men and women are equally likely to inherit the disorder, as it follows an autosomal dominant inheritance pattern. Overall, approximately 1 in every 10,000 people in the general population may be affected by Huntington's disease.
