RCV002027439 | SCV002309575 | uncertain significance | Facioscapulohumeral muscular dystrophy 2 | 2023-02-07 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with SMCHD1-related conditions. This variant is present in population databases (rs758405083, gnomAD 0.006%). This sequence change replaces histidine, which is basic and polar, with proline, which is neutral and non-polar, at codon 1518 of the SMCHD1 protein (p.His1518Pro). ClinVar contains an entry for this variant (Variation ID: 1517556). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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 not expected to disrupt SMCHD1 protein function. |
