In this study, Mainland and colleagues de-orphan 18 human odorant receptors and find that 68% of these receptors exhibit polymorphisms that affect their function in vitro. They also show that the polymorphisms in one these odorant receptors, OR10G4, affect odor intensity and valence perception thus linking the molecular functioning of a single odorant receptor to human olfactory perception.
