| Invitae | RCV000794088 | SCV000933474 | uncertain significance | Charcot-Marie-Tooth disease type 2 | 2022-10-18 | criteria provided, single submitter | clinical testing | 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on LMNA protein function. ClinVar contains an entry for this variant (Variation ID: 640948). This missense change has been observed in individual(s) with clinical features of LMNA-related conditions (PMID: 32793522). This variant is present in population databases (rs777419380, gnomAD 0.0009%). This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 200 of the LMNA protein (p.Met200Val). |
