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]

This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 16 of the WNT2B protein (p.Arg16Pro). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with WNT2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 2086741). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
