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]

The c.98C>T (p.S33L) alteration is located in exon 2 (coding exon 1) of the CSNK1G3 gene. This alteration results from a C to T substitution at nucleotide position 98, causing the serine (S) at amino acid position 33 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
