RCV002899238 | SCV003243805 | pathogenic | Telangiectasia, hereditary hemorrhagic, type 2 | 2023-06-02 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 330 of the ACVRL1 protein (p.Asp330Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of hereditary hemorrhagic telangiectasia (Invitae). ClinVar contains an entry for this variant (Variation ID: 2036560). 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. This variant disrupts the p.Asp330 amino acid residue in ACVRL1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12114496, 16429404, 18673552, 23124896). 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. |
