Interventions/Control_1
We are going to select the subjects who have wild-type / wild-type genotype about a certain missense mutation of olfactory receptor gene X and get them evaluate three odors.
Interventions/Control_2
We are going to select the subjects who have wild-type / mutant genotype about a certain missense mutation of olfactory receptor gene X and get them evaluate three odors.
Interventions/Control_3
We are going to select the subjects who have mutant / mutant genotype about a certain missense mutation of olfactory receptor gene X and get them evaluate three odors.
