Autopsy-proven Huntington's disease with 29 trinucleotide repeats

Huntington's disease (RD) is a neurodegenerative disorder associated with expansion of CAG trinucleotide repeats in the huntingtin gene. A minimum of 36 CAG repeats is usually reported in patients with clinical features of RD; 30 to 35 repeats represent an intermediate range. Here we report a 65-year-old male with autopsy-proven HD and 29 CAG repeats. (C) 2006 Movement Disorder Society.
