Variant summary
Our verdict is Likely pathogenic. Variant got 6 ACMG points: 7P and 1B. PM1PM2PP2PP5_ModerateBP4
The NM_021625.5(TRPV4):c.832G>A(p.Glu278Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E278D) has been classified as Uncertain significance.

Charcot-Marie-Tooth disease axonal type 2C Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 05, 2022 | For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects TRPV4 function (PMID: 22702953). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt TRPV4 protein function. ClinVar contains an entry for this variant (Variation ID: 18434). This missense change has been observed in individuals with spondylometaphyseal dysplasia and skeletal dysplasia with peripheral neuropathy (PMID: 20577006, 22419508). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 278 of the TRPV4 protein (p.Glu278Lys). - |
