Genes affected

WNT10A (HGNC:13829): (Wnt family member 10A) 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 is strongly expressed in the cell lines of promyelocytic leukemia and Burkitt's lymphoma. In addition, it and another family member, the WNT6 gene, are strongly coexpressed in colorectal cancer cell lines. The gene overexpression may play key roles in carcinogenesis through activation of the WNT-beta-catenin-TCF signaling pathway. This gene and the WNT6 gene are clustered in the chromosome 2q35 region.

The c.275C>T (p.A92V) alteration is located in exon 2 (coding exon 2) of the WNT10A gene. This alteration results from a C to T substitution at nucleotide position 275, causing the alanine (A) at amino acid position 92 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with clinical features of WNT10A-related conditions (Invitae). It has also been observed to segregate with disease in related individuals. 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. This sequence change replaces alanine with valine at codon 92 of the WNT10A protein (p.Ala92Val). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and valine. -
