Invitae RCV000805747 SCV000945715 pathogenic Charcot-Marie-Tooth Neuropathy X 2018-12-28 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with lysine at codon 208 of the GJB1 protein (p.Glu208Lys). 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 (ExAC no frequency). This variant has been observed in several individuals affected with X-linked Charcot-Marie-Tooth disease (CMT) and has been reported to segregate with CMT in families (PMID: 8162049, 10737979, 14960772, 17646144, 25429913, 28448691). ClinVar contains an entry for this variant (Variation ID: 447439). This variant has been reported to affect GJB1 protein function (PMID: 9364054, 9592087, 10848620, 15006706). For these reasons, this variant has been classified as Pathogenic.
