Genes affected

CWF19L1 (HGNC:25613): (CWF19 like cell cycle control factor 1) This gene encodes a member of the CWF19 protein family. Mutations in this gene have been associated with autosomal recessive spinocerebellar ataxia-17 and mild cognitive disability. Alternative splicing results in multiple transcript variants.
