Presence of rs5906957 in MAOA (P = 0.005), rs25531 in 5-HTT (P = 0.007) and rs4680 in COMT (P = 0.001) were associated with higher anxiety scale in group D. There was significant correlation between presence of rs1076560 in DRD2 (P = 0.002), rs4680 in COMT (P = 0.003) and rs6265 in BDNF (P = 0.006) with higher stress scale in group B. Significant correlation was detected between presence of rs4680 in COMT (P = 0.001) and rs6265 in BDNF (P = 0.003) and higher stress scale in group D. This evidence concerns the gene MAOA and Anxiety.
