Distributions of 5-HTTVNTR polymorphism and allele frequencies of the subjects

Genotypes: χ²=5.12, df=2, p=0.08(p_corr=0.16); alleles: χ²=4.29, df=1, p=0.04 (p_corr=0.08); allele carriers: χ²=4.93, df=1, p=0.026 (p_corr=0.052). 10⁺: 10 carrier, 10-:10 non-carrier. ^*Hardy-Weinberg equilibrium test for suicidal group: χ²=2.969, df=1, p=0.08, ^†Hardy-Weinberg equilibrium test for control group: χ²=2.668, df=1, p=0.10. p_corr: p-value after Bonferroni correction, MDD: major depressive disorder
