OR2L8

Chr 1

olfactory receptor family 2 subfamily L member 8

NCBI Gene: 391190 ENSG00000279263 UniProt: Q8NGY9

OR2L8 encodes an olfactory receptor that interacts with odorant molecules to initiate neuronal responses triggering smell perception through G-protein-coupled receptor signaling. This gene is a segregating pseudogene where some individuals carry functional alleles while others have non-functional variants, but no Mendelian diseases have been associated with OR2L8 mutations. The gene shows low constraint to loss-of-function variation (pLI 0.32, LOEUF 1.86), consistent with its variable functionality across the population.

ResearchSummary from RefSeq, UniProt

Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. This olfactory receptor gene is a segregating pseudogene, where some individuals have an allele that encodes a functional olfactory receptor, while other individuals have an allele encoding a protein that is predicted to be non-functional.

Interpreting a novel variant

This gene is strongly intolerant of loss-of-function variation in the population, so LoF variants warrant close attention. No curated mechanism annotation is available — see the mechanism card for the computational prediction and its caveats.Based on population constraint only.
