Since then, RAN translation has been investigated and detected in many microsatellite expansion-associated diseases [104] including fragile X-associated tremor/ataxia syndrome (FXTAS) (CGG•CCG) [105], myotonic dystrophy type 2 (CCTG•CAGG) [106], spinocerebellar ataxia type 31 (SCA31) (TGGAA•TTCCA) [107], SCA36 (TGGGCC•GGCCCA) [108], Huntington’s disease (CAG•CTG) [109], and C9ORF72-ALS/FTD (GGGGCC•GGCCCC) [110–112]. This evidence concerns the gene RAN and spinocerebellar ataxia type 31.
