OR1E2

Chr 17

olfactory receptor family 1 subfamily E member 2

Also known as: OR17-135, OR17-136, OR17-93, OR1E4, OR1E7, OST529

This gene encodes an olfactory receptor that recognizes and transduces odorant signals through G-protein-coupled receptor signaling in the nasal epithelium. Currently, no specific pediatric neurological diseases have been definitively associated with OR1E2 mutations. The gene shows low constraint to loss-of-function variation (pLI 0.0016, LOEUF 1.43), consistent with the functional redundancy typical of the large olfactory receptor gene family.

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.
