OR5M11

Chr 11

olfactory receptor family 5 subfamily M member 11

Also known as: OR11-199

NCBI Gene: 219487 ENSG00000255223 UniProt: Q96RB7

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. [provided by RefSeq, Jul 2008]

Background carrier burden — how many people carry a rare variant somewhere in OR5M11?

gnomAD v4 · ~731k individuals · PASS only

Rare means allele frequency under

Rare missense

1 in 87

443 rare PASS variants

Rare truncating (LoF)

1 in 3,100

42 rare PASS variants

Rare synonymous (reference)

1 in 150

195 rare PASS variants

Truncating variants are far rarer here than missense — that gap, in human units, is what constraint means for OR5M11. A background rate for each class, not the frequency of any particular variant; thin-coverage exons undercount.

By genetic ancestry · 9 gnomAD groups · rare = under 0.1% in that group

European (non-Finnish)	~556k	1 in 160	1 in 10,000

Each group is summed over the variants that are rare in that group. Grey ≈ figures rest on fewer than five expected carriers — too few to distinguish groups. Differences mostly reflect how many people were sampled and how much variation each ancestry carries, not disease risk.
