Huntington's disease known as inherited chronic chorea is an autosomal dominant disorder. After collection of a large HD pedigree from HuBei, the molecular diagnosis of the patients, the pre-symptomatic diagnosis of the persons on risk and the genetic analysis of this pedigree are performed so that the pathogene of this family can be confirmed.
