Genes affected

WIPF1 (HGNC:12736): (WAS/WASL interacting protein family member 1) This gene encodes a protein that plays an important role in the organization of the actin cytoskeleton. The encoded protein binds to a region of Wiskott-Aldrich syndrome protein that is frequently mutated in Wiskott-Aldrich syndrome, an X-linked recessive disorder. Impairment of the interaction between these two proteins may contribute to the disease. Two transcript variants encoding the same protein have been identified for this gene.

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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals with WIPF1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with aspartic acid at codon 494 of the WIPF1 protein (p.Gly494Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid. -
