Labcorp Genetics (formerly Invitae), Labcorp RCV000640445 SCV000762036 likely pathogenic Telangiectasia, hereditary hemorrhagic, type 2 2023-08-08 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Arg374 amino acid residue in ACVRL1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 9245985, 12700602, 18285823, 20501893, 21158752, 22991266, 23722869, 25970827). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 ACVRL1 protein function. ClinVar contains an entry for this variant (Variation ID: 533351). This missense change has been observed in individual(s) with clinical features of hereditary hemorrhagic telangiectasia (Invitae). This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 374 of the ACVRL1 protein (p.Arg374Pro).
