In humans, there is considerable variation between individuals in their sensitivity to certain smells and their subjective experience of them. This paper identifies a potential genetic source of variability in perception of odorous steroids. OR7D4, an odorant receptor, is selectively activated in vitro by androstenone and variants of the gene are associated with differences in psychophysical performance in human subjects
