WebThe diagnosis of HD is based on family history, characteristic clinical findings, and the detection of an expansion of a CAG polyglutamine tract in the Huntingtin gene. Juvenile HD is characterized by paternal anticipation and large CAG expansions that may be missed using routine molecular analysis. WebTrinucleotide repeat disorders exhibit a phenomenon known as anticipation. The triplet repeat mutation is unstable and can expand between subsequent generations. In general, a larger expansion causes a more severe form of the disease. This means that these conditions become more severe in successive generations of the same family.
