rs4481887
rs4481887 is an intergenic SNP on the telomeric end of chromosome 1q, positioned between the olfactory receptor genes OR2M7 and OR14C36 within a cluster of roughly 50 olfactory receptor genes; it is not itself assigned to a coding gene, and its functional mechanism is inferred to affect nearby OR2M7 signaling rather than confirmed at the molecular level. The A allele is associated with greater ability to smell the characteristic sulfurous odor that certain metabolites of asparagus produce in urine, while G-allele carriers are less likely to perceive it. It is the sole marker used for asparagus odor detection in this dataset.
