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.

The c.1283C>T (p.T428I) alteration is located in exon 12 (coding exon 12) of the CWF19L1 gene. This alteration results from a C to T substitution at nucleotide position 1283, causing the threonine (T) at amino acid position 428 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
