Genes affected

WNT3A (HGNC:15983): (Wnt family member 3A) The WNT gene family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. This gene is a member of the WNT gene family. It encodes a protein which shows 96% amino acid identity to mouse Wnt3A protein, and 84% to human WNT3 protein, another WNT gene product. This gene is clustered with WNT14 gene, another family member, in chromosome 1q42 region. [provided by RefSeq, Jul 2008]

The c.178G>A (p.V60M) alteration is located in exon 2 (coding exon 2) of the WNT3A gene. This alteration results from a G to A substitution at nucleotide position 178, causing the valine (V) at amino acid position 60 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant is present in population databases (rs199976080, gnomAD 0.03%). This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 60 of the WNT3A protein (p.Val60Met). This variant has not been reported in the literature in individuals affected with WNT3A-related conditions. 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. -
