OR13J1

Chr 9

olfactory receptor family 13 subfamily J member 1

Also known as: OR9-2

OR13J1 encodes an olfactory receptor that binds odorant molecules in the nose and initiates G protein-coupled signaling to trigger smell perception. This gene is not associated with any known pediatric neurogenetic disorders. The gene shows no evidence of evolutionary constraint, with variants that disrupt protein function being well-tolerated in the general population.

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.
