Invitae RCV000556540 SCV000639563 uncertain significance Charcot-Marie-Tooth disease, dominant intermediate C 2019-10-15 criteria provided, single submitter clinical testing This sequence change replaces lysine with asparagine at codon 265 of the YARS protein (p.Lys265Asn). The lysine residue is weakly conserved and there is a moderate physicochemical difference between lysine and asparagine. This variant is present in population databases (rs141482636, ExAC 0.01%). This variant has been reported in an individual affected with peripheral neuropathy and an unaffected control individual (PMID: 21384131). Experimental studies have shown that this missense change is non-pathogenic in a Drosophila model (PMID: 21384131). In summary, this variant is a rare missense change that is not predicted to affect protein function. It has been reported in both the population and an affected individual, but the available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
