OR5C1

Chr 9

olfactory receptor family 5 subfamily C member 1

Also known as: OR5C2P, OR9-31, OR9-F

The protein functions as an odorant receptor that binds odorant molecules in the nose and initiates G protein-mediated signal transduction to trigger smell perception. Based on the extremely low pLI score and high LOEUF score, this gene appears highly tolerant to loss-of-function variants, and no disease associations have been established for OR5C1 mutations in the current literature.

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.
