OR1L6

Chr 9

olfactory receptor family 1 subfamily L member 6

Also known as: HG16, OR1L7, OR9-30

This protein is an olfactory receptor that detects odorant molecules and initiates G-protein-coupled signaling to trigger smell perception. Currently, no Mendelian diseases are definitively associated with mutations in this gene. The gene shows very low constraint against loss-of-function variants, which is typical for olfactory receptor genes given their large family size and functional redundancy.

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.
