This gene is associated with the defense of the upper airway where it is activated by acylhomoserine lactones. The increased likelihood of developing respiratory infections can be due to genetic differences (Lee. 2012). In a study where PROP - similar to PTC - was used as a probe for these variances in sensing the bitter taste, bitterness varied significantly with different genotypes (Duffy, 2004). Additionally, when exploring the importance of PTC, it was reported that tasting PTC had a correlation to tasting other toxic substances (Woodling, 2004). For this reason it is important to understand the influence of different genotypes for the expression of the taster
