Invitae RCV001241644 SCV001414675 uncertain significance Charcot-Marie-Tooth disease axonal type 2C 2019-10-07 criteria provided, single submitter clinical testing This sequence change replaces glycine with serine at codon 809 of the TRPV4 protein (p.Gly809Ser). The glycine residue is moderately conserved and there is a small physicochemical difference between glycine and serine. This variant is present in population databases (rs375851168, ExAC 0.01%). This variant has not been reported in the literature in individuals with TRPV4-related conditions. ClinVar contains an entry for this variant (Variation ID: 448709). 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.
