Invitae RCV000638155 SCV000759641 pathogenic Charcot-Marie-Tooth disease, type I 2018-10-29 criteria provided, single submitter clinical testing This sequence change replaces threonine with methionine at codon 124 of the MPZ protein (p.Thr124Met). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is not present in population databases (ExAC no frequency). This variant has been reported to segregate with Charcot-Marie-Tooth disease in multiple families (PMID: 12948789, 15159512, 19629567, 25720167) and has also been reported in several unrelated affected individuals (PMID: 9452091, 26234237, 12207153, 10923043, 16279991). ClinVar contains an entry for this variant (Variation ID: 14181). Experimental studies have shown that this missense change decreases myelin protein zero mediated intracellular adhesion (PMID: 20461396, 18337304). For these reasons, this variant has been classified as Pathogenic.
