These genetic loci include ATXN1, ATXN2, ATXN3, CACNA1A, ATXN7, ATXN8OS, ATXN10, PPP2R2B, TBP, ATN1, FMR1, BEAN1, NOP56, GLS, THAP11, GAA-FGF14, ZFHX3, FXN and RFC1. This study aims to assess the yield of short-read whole genome sequencing in the molecular diagnosis of hereditary cerebellar ataxia. Here, RFC1 is linked to hereditary cerebellar ataxia.
