GPR82

G protein-coupled receptor 82

GPR82 encodes an orphan G protein-coupled receptor with seven transmembrane domains that transduces extracellular signals through heterotrimeric G proteins, though its specific ligand and function remain unknown. Currently, no established human diseases have been definitively associated with GPR82 mutations. The gene shows tolerance to loss-of-function variants (pLI = 0.14, LOEUF = 1.08), suggesting it may not be essential for normal development.

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.

GOFprediction above median
DNprediction above median

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.
