Variant summary

Our verdict is Benign. Variant got -19 ACMG points: 1P and 20B. PP2 BP4_Strong BP6_Very_Strong BA1

The NM_021625.5(TRPV4):c.55C>T(p.Pro19Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0306 in 1,586,158 control chromosomes in the GnomAD database, including 866 homozygotes. In-silico tool predicts a benign outcome for this variant. 11/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Synonymous variant affecting the same amino acid position (i.e. P19P) has been classified as Likely benign.

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

Verdict is Benign. Variant got -19 ACMG points.

• PP2: Missense variant where missense usually causes diseases, TRPV4
• BP4: Computational evidence support a benign effect (MetaRNN=0.0023634434).
• BP6: Variant 12-109814742-G-A is Benign according to our data. Variant chr12-109814742-G-A is described in ClinVar as [Benign]. Clinvar id is 5003.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr12-109814742-G-A is described in Lovd as [Benign]. Variant chr12-109814742-G-A is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.0536 is higher than 0.05.
