GPRC5C

Chr 17

G protein-coupled receptor class C group 5 member C

Also known as: RAIG-3, RAIG3

This G protein-coupled receptor mediates cellular effects of retinoic acid on G protein signaling pathways through its 7-transmembrane domain structure. The specific neurological phenotypes associated with GPRC5C mutations and their inheritance pattern are not established based on the available data. Mutations are predicted to cause disease through a gain-of-function mechanism.

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.
