Huntington disease primarily affects adults, typically appearing between the ages of 30 and 50, though symptoms can manifest earlier or later. It has an autosomal dominant inheritance pattern, meaning that each child of an affected parent has a 50% chance of inheriting the disease. The prevalence of Huntington disease is estimated to be about 5 to 10 cases per 100,000 people in Caucasian populations, with variations in frequency among different ethnic groups.
World wide around 8 cases per 100,000 persons are affected by Huntington's Disease. The number varies somewhat because it is genetic.
Less than 1 in 10,000
In the United States, about 1 in every 30,000 people has Huntington's Disease.
Yes. Since HD is carried on a dominant gene, it is not possible to be a carrer, and not be affected by the disease.
Huntington's Chorea

A. Huntington's disease and neurofibromatosis type 1 are examples of autosomal dominant diseases. These conditions are caused by a single copy of a mutated gene on an autosome (non-sex chromosome) and can be passed down from one affected parent to their offspring with a 50% chance of inheritance.
how many people are affected by parkinson's disease?
Mainly people of English descent, that have at least one parent that has the gene for HD.
The number of charities focused on Huntington's disease varies by region, but there are several prominent organizations globally. Notable examples include the Huntington's Disease Society of America (HDSA) in the U.S., the Huntington Society of Canada, and the European Huntington's Disease Network in Europe. Additionally, many local and smaller charities may exist, contributing to research, support, and advocacy efforts for those affected by the disease. Overall, the landscape of Huntington's disease charities is diverse, reflecting the global need for awareness and support.
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.
