OR2T29

Chr 1

olfactory receptor family 2 subfamily T member 29

OR2T29 encodes an olfactory receptor that binds odorant molecules and initiates G-protein-coupled signaling to trigger smell perception. This gene is not well-established as a cause of human disease, and loss-of-function variants are generally well-tolerated given its low constraint scores. Individual olfactory receptor genes typically do not cause clinically significant phenotypes due to functional redundancy within the large olfactory receptor gene family.

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.
