Genes affected
WNT2B (HGNC:12781): (Wnt family member 2B) This gene encodes a member of the wingless-type MMTV integration site (WNT) family of highly conserved, secreted signaling factors. WNT family members function in a variety of developmental processes including regulation of cell growth and differentiation and are characterized by a WNT-core domain. This gene may play a role in human development as well as carcinogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]

The c.65T>C (p.V22A) alteration is located in exon 1 (coding exon 1) of the WNT2B gene. This alteration results from a T to C substitution at nucleotide position 65, causing the valine (V) at amino acid position 22 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
