Invitae RCV002513737 SCV003523910 pathogenic Charcot-Marie-Tooth disease type 2 2022-08-28 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg453 amino acid residue in LMNA. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 10080180, 14749366, 18396274, 20980393, 21173262, 22326558, 24642510). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 66808). This missense change has been observed in individual(s) with autosomal dominant congenital muscular dystrophy (PMID: 18551513, 34240052). In at least one individual the variant was observed to be de novo. This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 453 of the LMNA protein (p.Arg453Pro).
