ATXN10 Microsatellite Distribution in a Peruvian Amerindian Population

Spinocerebellar ataxia type 10 (SCA10) is a repeat expansion disease occurring mostly in Latin America, suggesting that the mutation spread with the peopling of the Americas, or that Amerindian populations, have a higher ATXN10 mutability. High frequency of large normal alleles is associated with prevalence and relative frequency of other repeat expansion diseases. To test whether the allele distribution of the SCA10-causing ATXN10...
