OXGR1

Chr 13AD

oxoglutarate receptor 1

Also known as: CAON2, GPR80, GPR99, P2RY15, P2Y15, aKGR

NCBI Gene: 27199ENSG00000165621UniProt: Q96P68OMIM: 606922

The protein functions as a G protein-coupled receptor that binds dicarboxylates including alpha-ketoglutarate, itaconate, and leukotriene E4, regulating renal salt reabsorption, respiratory mucociliary clearance, and mucin release in response to allergens. Mutations cause autosomal dominant nephrolithiasis with calcium oxalate stones and nephrocalcinosis. The gene shows low constraint to loss-of-function variation (pLI 0.00005, LOEUF 1.588), suggesting tolerance to protein-truncating variants.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
