Invitae | RCV001971051 | SCV002258765 | likely pathogenic | Multiple congenital exostosis | 2024-01-16 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 151 of the EXT1 protein (p.Ala151Glu). This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with hereditary multiple osteochondromatosis (Invitae). ClinVar contains an entry for this variant (Variation ID: 1474153). 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 EXT1 protein function with a positive predictive value of 80%. 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. |
