Labcorp Genetics (formerly Invitae), Labcorp RCV001206664 SCV001377984 pathogenic Hereditary hemorrhagic telangiectasia 2023-05-27 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 269 of the ENG protein (p.Met269Arg). This missense change has been observed in individual(s) with hereditary hemorrhagic telangiectasia (PMID: 20414677; Invitae). ClinVar contains an entry for this variant (Variation ID: 937612). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ENG protein function. This variant disrupts the p.Met269 amino acid residue in ENG. Other variant(s) that disrupt this residue have been determined to be pathogenic (Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
