|Annotation=This SNP is part of a haplogroup found to be associated with CAG repeat number expansion in Huntington disease (36 or more CAG repeats) in Europeans and also with intermediate expansion(27-35 repeats) in unaffected individuals(Europeans). This SNP itself was significantly associated(p < 0.0023) with the expansion.
