Longer allele lengths in two other genes with established relationship to disease, RFC1 (OMIM#102579) (AAAG Expansion), associated with autosomal recessive cerebellar ataxia, neuropathy, and vestibular areflexia syndrome (OMIM#614575,) and ATXN10 (OMIM#611150) (ATTCT Expansion), associated with autosomal dominant spinocerebellar ataxia 10 (OMIM#603516), were also present in the proband cohort. The gene discussed is RFC1; the disease is autosomal recessive cerebellar ataxia.
