ADIPOR2

Chr 12

adiponectin receptor 2

Also known as: ACDCR2, PAQR2

ADIPOR2 encodes adiponectin receptor 2, which binds the hormone adiponectin and activates signaling pathways that regulate fatty acid oxidation and glucose uptake. Mutations in this gene cause autosomal recessive diabetes mellitus. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.518), suggesting some intolerance to complete protein loss.

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

GOFprediction 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.
