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.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 485 of the WIPF1 protein (p.Arg485Gln). This variant is present in population databases (rs776761827, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with WIPF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 862621). 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. -
