Spinocerebellar ataxia type 10 (SCA10): Mutation analysis and common haplotype based inference suggest its rarity in Indian population.

ABSTRACT: Spinocerebellar ataxia type 10 (SCA10) is a rare autosomal dominant cerebellar ataxia caused by nucleotide ATTCT expansion in ATXN10 gene. SCA10 has been reported in patients of cerebellar ataxia from Amerindian/Latin America and in East Asian ancestry. A common founder has been ascribed to the origin of ATTCT repeat expansion mutation in both the population. Here we present our investigation of the SCA10 pentanucleotide repeat expansion in 461 SCA patients of the Indian population. The analysis of multi-ethnic at-risk haplotype C-(ATTCT)n-GGC was performed using genotype data of various ethnic population included in the 1000 Genomes Project (KGP) to infer the prevalence of at-risk haplotype in the Indian populations. Unsurprisingly, none of the patient's DNA samples with (AT
