Variant summary

Our verdict is Benign. The variant received -17 ACMG points: 1P and 18B. PP3BP4_ModerateBP6_Very_StrongBS1BS2

The NM_021625.5(TRPV4):c.1337G>T(p.Arg446Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000149 in 1,613,684 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R446C) 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: Benign. The variant received -17 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 9: AlphaMissense, BayesDel_noAF, Cadd, M_CAP, MutationAssessor, PrimateAI, PROVEAN, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.1650761).

BP6

Variant 12-109794483-C-A is Benign according to our data. Variant chr12-109794483-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 448707.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000828 (126/152136) while in subpopulation AFR AF = 0.00263 (109/41514). AF 95% confidence interval is 0.00223. There are 1 homozygotes in GnomAd4. There are 58 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
