3billion RCV003314389 SCV004013699 uncertain significance Wiskott-Aldrich syndrome criteria provided, single submitter clinical testing The variant is not observed in the gnomAD v2.1.1 dataset. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.83; 3Cnet: 0.93). However, the evidence of pathogenicity is insufficient at this time. Therefore, this variant is classified as Uncertain significance according to the recommendation of ACMG/AMP guideline.
Labcorp Genetics (formerly Invitae), Labcorp RCV003777282 SCV004611119 uncertain significance X-linked severe congenital neutropenia; Thrombocytopenia 1; Wiskott-Aldrich syndrome 2023-11-10 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 129 of the WAS protein (p.Ala129Pro). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with WAS-related conditions. ClinVar contains an entry for this variant (Variation ID: 2572504). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt WAS protein function with a positive predictive value of 80%. 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.
