OR13C9

Chr 9

olfactory receptor family 13 subfamily C member 9

Also known as: OR37L, OR9-13

This gene encodes an olfactory receptor that recognizes odorant molecules and initiates G protein-mediated signal transduction for smell perception. No disease associations have been established for OR13C9 mutations, and the gene shows tolerance to loss-of-function variants based on population genetics data.

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.

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.
