Invitae RCV000700159 SCV000828904 pathogenic Charcot-Marie-Tooth disease, type 2 2020-01-07 criteria provided, single submitter clinical testing This sequence change replaces arginine with proline at codon 527 of the LMNA protein (p.Arg527Pro). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and proline. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals and families affected with autosomal dominant muscular dystrophies, and to segregate with the disease in affected families (PMID: 10080180, 19084400, 20980393). ClinVar contains an entry for this variant (Variation ID: 14481). This variant has been reported to affect LMNA protein function (PMID: 16218190, 19933576). This variant disrupts the p.Arg527 amino acid residue in LMNA. Other variant(s) that disrupt this residue (p.Arg527His, p.Arg527Cys) have been determined to be pathogenic (PMID: 12075506, 14627682, 18604166, 25823658, 25324471, 19432833, 23497705, 25286833). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
