DAB1 and spinocerebellar ataxia type 37: While triplet repeat expansions have been reported in various neurological diseases (i.e., spinocerebellar ataxias, DRPLA, Friedreich’s ataxia, Huntington’s disease, fragile X syndrome, and myotonic dystrophy), similar pentameric repeat expansions have been detected only in spinocerebellar ataxia 37 (SCA37), in the first intron of DAB1 [89,90].
