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 Benign. Variant got -16 ACMG points.

PP2

Missense variant where missense usually causes diseases, TRPV4

PP3

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_noAF, Cadd, M_CAP, MutationAssessor, PrimateAI, PROVEAN, REVEL [when 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 [Likely_benign]. Clinvar id 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 male gnomad4 subpopulation. This position pass quality control queck.

BS2

High AC in GnomAd at 125 AD gene.

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. -
