Genes affected
TRPV4 (HGNC:18083): (transient receptor potential cation channel subfamily V member 4) This gene encodes a member of the OSM9-like transient receptor potential channel (OTRPC) subfamily in the transient receptor potential (TRP) superfamily of ion channels. The encoded protein is a Ca2+-permeable, nonselective cation channel that is thought to be involved in the regulation of systemic osmotic pressure. Mutations in this gene are the cause of spondylometaphyseal and metatropic dysplasia and hereditary motor and sensory neuropathy type IIC. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2010]

Charcot-Marie-Tooth disease axonal type 2C Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 04, 2023 | This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 407 of the TRPV4 protein (p.Lys407Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with autosomal dominant spondylometaphyseal dysplasia (PMID: 21658220; Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 126463). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TRPV4 protein function. For these reasons, this variant has been classified as Pathogenic. - |
