Variant chr12-109803033-T-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 7P and 4B. PM1PM2PP2PP3_ModerateBS2

The NM_021625.5(TRPV4):c.670A>T(p.Arg224Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,680 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R224Q) 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 made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 8 uncertain in NM_021625.5

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TRPV4. . Gene score misZ 1.9225 (greater than the threshold 3.09). Trascript score misZ 3.5609 (greater than threshold 3.09). GenCC has associacion of gene with TRPV4-related bone disorder, metatropic dysplasia, Charcot-Marie-Tooth disease axonal type 2C, spondylometaphyseal dysplasia, Kozlowski type, familial avascular necrosis of femoral head, parastremmatic dwarfism, neuromuscular disease, autosomal dominant brachyolmia, familial digital arthropathy-brachydactyly, neuronopathy, distal hereditary motor, autosomal dominant 8, scapuloperoneal spinal muscular atrophy, autosomal dominant.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.889

BS2

High AC in GnomAdExome4 at 5 AD gene.
