rs4481887
rs4481887 is a non-coding marker in a chromosome 1 olfactory-receptor region. In European-ancestry studies, people with at least one A copy were more likely than GG participants to notice the characteristic odor in urine after eating asparagus. The marker shifts detection likelihood, does not show whether a person produces the odor, and is not proven causal.
