OR5H6

Chr 3

olfactory receptor family 5 subfamily H member 6

Also known as: OR3-11

OR5H6 encodes an olfactory receptor that detects odorant molecules in the nose and initiates G-protein-coupled signaling to trigger smell perception. This gene is a segregating pseudogene where some individuals carry functional alleles while others have non-functional variants, and it shows no constraint against loss-of-function variants in the population. No Mendelian diseases have been definitively associated with OR5H6 mutations.

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.
