RCV005080202 | SCV005712095 | uncertain significance | Charcot-Marie-Tooth disease axonal type 2Z | 2024-07-30 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 881 of the MORC2 protein (p.Ile881Thr). This variant is present in population databases (rs761366027, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with MORC2-related conditions. 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 MORC2 protein function with a negative predictive value of 95%. 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. |
