A rapid genotyping assay for segregating human olfactory receptor pseudogenes.

ABSTRACT: Variation in odor perception between individuals is initiated by binding of "odorant" molecules to olfactory receptors (ORs) located in the nasal cavity. To determine the mechanism for variation in odor perception, identification of specific ligands for a large number of ORs is required. However, it has been difficult to identify specific ligands, and ligands have been identified for only 2-3% of the hundreds of mammalian ORs. One way to increase the number of identified ligands is to take advantage of >60 human OR genes that are segregating as a result of a single nucleotide polymorphism, between a functional intact allele and a nonfunctional pseudogene allele. Potential ligands for these ORs can be identified by correlating odor perception of an individual with their genotype [intact/int
