Labcorp Genetics (formerly Invitae), Labcorp RCV000558277 SCV000630547 uncertain significance Gastrointestinal stromal tumor 2023-12-02 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 425 of the PDGFRA protein (p.His425Tyr). This variant is present in population databases (rs759374919, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PDGFRA-related conditions. ClinVar contains an entry for this variant (Variation ID: 458994). 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 PDGFRA protein function with a negative 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.

Ambry Genetics RCV004943950 SCV005471021 likely benign Hereditary cancer-predisposing syndrome 2024-08-20 criteria provided, single submitter clinical testing This alteration is classified as likely 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.
