WebJul 26, 2011 · Huntington’s disease (HD) is caused by an expansion in the Huntington gene, which codes for the huntingtin protein. This gene contains a repeated span of three nucleotides, C-A-G, that encode for the amino acid glutamine. Individuals with an increased number of CAG repeats in the HD gene thus produce a mutated version of the huntingtin ... WebINTRODUCTION. Huntington’s disease (HD) is caused by the expansion of a CAG repeat in exon one of the HTT gene. Affected individuals inherit ≥36 CAG repeats and longer alleles are associated with earlier onset, greater disease severity and faster disease progression [].The HTT CAG repeat is genetically unstable in the germline, which …

WebHuntington disease is a hereditary trinucleotide repeat expansion disease, resulting from an aberrant CAG-encoded polyglutamine stretch. The site of this expansion is located on chromosome 4 at 4p16.3, a locus termed “interesting trasnscript 15,” or IT15, which codes for a 348-kDa protein called huntingtin , 11 bearing little homology to ... WebHuntington disease is inherited in an autosomal dominant manner. It is caused by a CAG repeat expansion in the HTT gene which occurs in the first exon, and encodes a … first african american woman attorney general
