Labcorp Genetics (formerly Invitae), Labcorp RCV000802068 SCV000941881 uncertain significance not provided 2023-07-07 criteria provided, single submitter clinical testing 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 not expected to disrupt CTNNA1 protein function. ClinVar contains an entry for this variant (Variation ID: 647541). This variant has not been reported in the literature in individuals affected with CTNNA1-related conditions. This variant is present in population databases (rs773756164, gnomAD 0.04%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 451 of the CTNNA1 protein (p.Arg451Gln). 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.
Ambry Genetics RCV002386429 SCV002689202 benign Hereditary cancer-predisposing syndrome 2021-08-18 criteria provided, single submitter clinical testing This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
