Labcorp Genetics (formerly Invitae), Labcorp RCV002002987 SCV002275409 pathogenic Telangiectasia, hereditary hemorrhagic, type 2 2024-08-28 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 294 of the ACVRL1 protein (p.Leu294Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with clinical features of hereditary hemorrhagic telangiectasia (PMID: 20414677; internal data). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 1482657). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt ACVRL1 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.
