Table 2 Observed distribution of genotypes at the TAS2R38 locus in the different categories of our cohort, used for association analysis

From: TAS2R38 taste receptor gene and chronic rhinosinusitis: new data from an Italian population

  CTL CRS Tot.
  CRSwNP CRSsNP
PAV/PAV 7 6 2 15
PAV/- 18 22 10 50
−/− 14 8 5 27
Tot. 39 36 17 92
  1. The number of subjects presenting a particular genotype in each category (CTL, CRS, CRSwNP, CRSsNP) was multiplied by Π in order to calculate the expected genotypic frequencies
  2. Π represents the fraction of individuals falling in each category on the total of subjects [Π(CTL) = 0.424 (39/92); Π(CRSwNP) (36/92) = 0.391; Π(CRSsNP) (17/92) = 0.185]
  3. Association between genotypes at the TAS2R38 locus and CRS was tested by χ 2
