Table 2 Genotype distributions and allele frequencies for G-308A mutation in theTNF-α gene in obese subjects and controls

From: The G-308A variant of the Tumor Necrosis Factor-α (TNF-α) gene is not associated with obesity, insulin resistance and body fat distribution

  1. GG, GA, and AA = TNF-α genotypes. Total obese subjects includes 17 patients whom did not undergo biolectric impedance analysis * Total obese subjects vs controls: genotypes Χ2 = 0.21, df = 2, p < NS; allele frequencies Χ2 = 0.09, df = 1, p < NS. # Central obese subjects vs controls: genotypes Χ2 = 2.4, df = 2, p < NS; allele frequencies Χ2 = 1.4, df = 1, p < NS. § Peripheral obese subjects vs controls: genotypes Χ2 = 0.95, df = 2, p < NS; allele frequencies Χ2 = 0.16, df = 1, p < NS. Central obese subjects vs peripheral obese subjects: genotypes Χ2 = 0.5, df = 1, p = NS; allele frequencies Χ2 = 0.4, df = 1, p = NS. Cutpoints for centrally obese subjects were : WC 94 for men and WC 88 for women
