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.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.1390G>A (p.A464T) alteration is located in exon 13 (coding exon 13) of the CWF19L1 gene. This alteration results from a G to A substitution at nucleotide position 1390, causing the alanine (A) at amino acid position 464 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
