male genotype
3.Results: The frequencies of DD genotype were 41 4% and 22 0%, ID genotype, 31 0% and 41 5%, II genotype, 27 6% and 36 6% in myocardial infaction and normal human respectively. The frequency of DD genotype in patients was higher than that in the control group, χ 2=4 21,P<0 05. There is no significant difference of DD genotype between male and female.
5.Results The genotype frequency of Gln223 Arg variant in leptin receptor gene was related with obesity which happened in male hypertensive patients; Allele A was associated with increased systolic blood pressure(P=0.023)and diastolic blood pressure(P=0.036)and BMI(P=0.031)in male hypertensive patients complicated with obesity.
7.P = 0.047 within GNB3 CC+CT genotype. The results suggest that ACE, or a nearby gene, is a male-specific susceptible gene for hypertension, and that there may exist epistatic gene-gene interaction between ACE D allele and GNB3 825C allele.
8.The risk of chromosomal damage induced by VCM for individuals carrying XRCC1 c. 194 Arg/Arg genotype was 0.6898(95% CI 0.4997-0.9333,P=0.0195)of those carrying Arg/Trp,Trp/Trp genotypes. The risk of chromosomal damage for female VCM exposure workers was 1.6000(95% CI 1.2284-2.0699, P=0.0004)of male workers.
