Huntington disease autosomal dominant pedigree
A Huntington disease pedigree is a family diagram used to discuss a reported autosomal dominant pattern. It arranges relatives by generation and marks affected and unaffected family members, with the proband identified when relevant. This can make a multigenerational family history easier to understand in an educational setting. The visual is not a diagnosis and cannot determine whether an individual has a genetic variant. Ages of onset, symptoms, test results, and personal circumstances matter and should be discussed with an appropriate clinician or genetic counselor. Share any health information carefully and only with the people who need it for the intended discussion.
