Genes affected

CSNK1G3 (HGNC:2456): (casein kinase 1 gamma 3) This gene encodes a member of a family of serine/threonine protein kinases that phosphorylate caseins and other acidic proteins. A related protein in the African clawed frog participates in the transmission of Wnt/beta-catenin signaling. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.305T>C (p.V102A) alteration is located in exon 5 (coding exon 4) of the CSNK1G3 gene. This alteration results from a T to C substitution at nucleotide position 305, causing the valine (V) at amino acid position 102 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
