GPR183

Chr 13

G protein-coupled receptor 183

Also known as: EBI2, hEBI2

NCBI Gene: 1880ENSG00000169508UniProt: P32249

GPR183 encodes a G-protein coupled receptor that binds oxysterols and mediates chemotactic positioning of immune cells including B-cells, T-cells, dendritic cells, and astrocytes during immune responses. The gene shows low constraint to loss-of-function variants, and no established human disease associations have been reported despite its role in immune cell positioning and astrocyte migration. Currently, no inherited disorders linked to GPR183 mutations are recognized in clinical practice.

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.
