Invitae RCV001058021 SCV001222556 uncertain significance Distal spinal muscular atrophy, autosomal recessive 4; Charcot-Marie-Tooth disease, recessive intermediate c 2019-05-07 criteria provided, single submitter clinical testing This sequence change replaces glycine with alanine at codon 176 of the PLEKHG5 protein (p.Gly176Ala). The glycine residue is weakly conserved and there is a small physicochemical difference between glycine and alanine. This variant is present in population databases (rs531190324, ExAC 0.009%). This variant has not been reported in the literature in individuals with PLEKHG5-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
