Genes affected

WWC2 (HGNC:24148): (WW and C2 domain containing 2) This gene encodes a member of the WW-and-C2-domain-containing family of proteins. Members of this family have two N-terminal WW domains that mediate binding to target proteins harboring L/PPxY motifs, an internal C2 domain for membrane association, and C-terminal alpha protein kinase C binding sites and class III PDZ domain-interaction motifs. Proteins of this family are able to form homo- and heterodimers and to modulate hippo pathway signaling. [provided by RefSeq, Sep 2016]

The c.553A>G (p.M185V) alteration is located in exon 5 (coding exon 5) of the WWC2 gene. This alteration results from a A to G substitution at nucleotide position 553, causing the methionine (M) at amino acid position 185 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
