Invitae RCV000470514 SCV000548856 pathogenic Charcot-Marie-Tooth disease, type 2 2018-11-07 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with lysine at codon 358 of the LMNA protein (p.Glu358Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. This variant is not present in population databases (rs60458016, ExAC no frequency). This variant has been reported in several individuals affected with Emery-Dreifuss muscular dystrophy, infantile inflammatory myopathy, and dilated cardiomyopathy (PMID: 10939567, 20980393, 23183350, 24508248, 21632249). This variant has also been reported in individuals in the Leiden Open-Source Variation Database, and was reported to arise de novo in individuals affected with Emery-Dreifuss muscular dystrophy and limb girdle muscular dystrophy (PMID: 21520333). ClinVar contains an entry for this variant (Variation ID: 14525). Experimental studies have shown that this missense change leads to mislocalization of the LMNA protein, with decreased nuclear rim staining and formation of intranuclear foci (PMID: 23427149, 11792809). For these reasons, this variant has been classified as Pathogenic.
