OR1D5

Chr 17

olfactory receptor family 1 subfamily D member 5

Also known as: C17orf2, OR17-2, OR17-31

NCBI Gene: 8386ENSG00000262628UniProt: P58170

OR1D5 encodes an olfactory receptor that binds odorant molecules and initiates G-protein-coupled signaling to trigger smell perception. No disease associations have been established for mutations in this gene. The gene shows low constraint to loss-of-function variation, which is typical for olfactory receptor genes.

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.
