Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 6P and 2B. PM1PM2PM5BP4_Moderate

The NM_021625.5(TRPV4):c.1627C>T(p.Leu543Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,828 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L543V) has been classified as Uncertain significance.

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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 8 uncertain in NM_021625.5

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr12-109793557-A-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 1683445.Status of the report is criteria_provided_single_submitter, 1 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.23181704).

This variant has not been reported in the literature in individuals with TRPV4-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with phenylalanine at codon 543 of the TRPV4 protein (p.Leu543Phe). The leucine residue is moderately conserved and there is a small physicochemical difference between leucine and phenylalanine. 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. 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. -
