Labcorp Genetics (formerly Invitae), Labcorp RCV000701585 SCV000830392 uncertain significance Wilms tumor 1 2024-04-29 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 109 of the GPC3 protein (p.Ala109Glu). This variant is present in population databases (rs761660909, gnomAD 0.02%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with GPC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 578546). 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 GPC3 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.
