Variation of CAG repeats and two intragenic polymorphisms at SCA3 locus among Machado–Joseph disease/SCA3 patients and diverse normal populations from eastern India

Objectives – MJD1/SCA3 is the most common type of spinocerebellar ataxia (SCA) worldwide. To explain the low prevalence of the disease among SCA patients from eastern India, we analysed CAG repeats and two bi‐allelic intragenic markers at SCA3 locus among 412 normal individuals and 10 patients.
