OR2B11

Chr 1

olfactory receptor family 2 subfamily B member 11

OR2B11 encodes an olfactory receptor that detects odorant molecules in the nose and initiates G protein-coupled signaling to trigger smell perception. This gene is not currently associated with any known pediatric neurogenetic disorders and shows low constraint to loss-of-function variation (pLI = 0.0002, LOEUF = 1.58), suggesting tolerance to genetic variation.

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.
