There at least 2 alleles for OR4E1. A non-functional allele results from a polymorphism at position 197 (dbSNP rs199890040), which leads to a frameshift, premature truncation of the coding region and hence pseudogenization. The presence of various combinations of functional (olfactory receptors) and non-functional (olfactory receptor segregating pseudogenes) alleles may underlie differences in olfactory sensitivity between individuals (hyperosmia, hyposmia or even anosmia).3 Publications
