Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 24, 2023 | 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. ClinVar contains an entry for this variant (Variation ID: 464167). This variant has not been reported in the literature in individuals affected with SMCHD1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 1534 of the SMCHD1 protein (p.Val1534Ala). - |
