چکیده

To the Editor: Huntington’s disease (HD) is a late onset, autosomal dominant neurodegenerative disorder characterised by progressive movement impairment, affective disturbance and cognitive dysfunction. In 2001, Huntington’s disease-like 2 (HDL2) was identified.1 The causative factor in both disorders is due to a repeat expansion mutation but these occur in two distinct genes: the IT15 gene (chromosome 4p16.3) for HD and the JPH3 gene (chromosome 16q24.3) for HDL2.
