Genes affected

WWC3 (HGNC:29237): (WWC family member 3) This gene encodes a member of the WWC family of proteins, which also includes the WWC1 (KIBRA) gene product and the WWC2 gene product. The protein encoded by this gene includes a C2 domain, which is known to mediate homodimerization in the related WWC1 gene product. [provided by RefSeq, Sep 2011]

The c.796G>A (p.A266T) alteration is located in exon 9 (coding exon 8) of the WWC3 gene. This alteration results from a G to A substitution at nucleotide position 796, causing the alanine (A) at amino acid position 266 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
