Invitae	RCV001039170	SCV001202684	uncertain significance	Distal spinal muscular atrophy, autosomal recessive 4; Charcot-Marie-Tooth disease, recessive intermediate c	2019-12-19	criteria provided, single submitter	clinical testing	This sequence change replaces threonine with methionine at codon 663 of the PLEKHG5 protein (p.Thr663Met). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is present in population databases (rs397515456, ExAC 0.03%). This variant has been observed in combination with another PLEKHG5 variant in an individual affected with Charcot-Marie-Tooth disease (PMID: 23844677). ClinVar contains an entry for this variant (Variation ID: 60780). This variant has been reported to affect PLEKHG5 protein function (PMID: 23844677). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
