Genes affected

TRPV5 (HGNC:3145): (transient receptor potential cation channel subfamily V member 5) This gene is a member of the transient receptor family and the TrpV subfamily. The calcium-selective channel encoded by this gene has 6 transmembrane-spanning domains, multiple potential phosphorylation sites, an N-linked glycosylation site, and 5 ANK repeats. This protein forms homotetramers or heterotetramers and is activated by a low internal calcium level. [provided by RefSeq, Jul 2008]

Renal Calcium Wasting Hypercalciuria

Pathogenic:1

Apr 04, 2023

Gene Mapping Laboratory, Hacettepe University

Significance: Pathogenic

Review Status: no assertion criteria provided

Collection Method: in vitro;research

The p.Val598Met variant is found in a family of 8 with 3 affected individuals (each has hypercalciuria). The variant is heterozygous in only 4 individuals in gnomAD and is not found in homozygosity in large population databases. Additional homozygosity mapping has excluded 98.85% of the genome for Identity-by-decent. Additional in vitro cell models show that cells transfected with p.Val598Met have lower calcium permeability and surface channel expression compared to cells transfected with the wild-type protein. The mutant protein also undergoes proteasomal degradation. -
