Invitae RCV000684901 SCV000812362 uncertain significance Charcot-Marie-Tooth disease type 2C 2018-03-15 criteria provided, single submitter clinical testing This sequence change replaces threonine with alanine at codon 175 of the TRPV4 protein (p.Thr175Ala). The threonine residue is weakly conserved and there is a small physicochemical difference between threonine and alanine. This variant is present in population databases (rs146304351, ExAC 0.009%). This variant has not been reported in the literature in individuals with TRPV4-related disease. Experimental studies have shown that this missense change disrupts TRPV4 protein function in vitro (PMID: 19661060). 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.
