METHODS We analyzed 11008 Japanese subjects, including 2797 cases(SBP ≥ 130 and DBP < 85 mmH g) who were not taking anti-hypertensive medication and 8211 controls(SBP < 130 and DBP < 85 mmH g), all of whom enrolled in the genome banking project of the 21 st Century COE(Center of Excellence) Program at Jichi Medical University. Subjects were divided into four groups according to gender(male and female) and age(≤ 49 years and ≥ 50 years). GNB3 gene polymorphism was determined using the TaqM an probe method. We compared the frequencies of alleles and genotypes between cases and controls by chi-squared test. The strength of the associations was estimated by odds ratios(ORs) and 95%CI by using logistic regression analysis. The ORs were adjusted for age and body mass index. RESULTS Allele and genotype distributions significantly differed between cases and controls only in males aged ≤ 49 years. Compared to the CC genotype, a significant OR was obtained in the TT genotype among males aged ≤ 49 years.CONCLUSION This study indicates that the TT genotype of the GNB3 C825 T SNP may contribute to SBP elevation of greater than 130 mmH g compared to the CC genotype in Japanese males aged ≤ 49 years.展开更多
