Ten alleles with length and nucleotide sequence variations were identified in the regulatory region of human tissue kallikrein gene. This present study aimed to study the polymorphisms of the regulatory region of human tissue kallikrein gene of the Chinese and investigate the relationship of the polymorphisms with essential hypertension. A case-control study was conducted in 200 hypertensive and 200 normotensive subjects of unrelated Chinese Han origin. All subjects were aged from 30 to 70 years and had no history of diabetes mellitus, kidney failure, or thyroid gland disease. The alleles were detected by polymerase chain reaction (PCR) and genotyping was performed with allele-specific oligonucleotide analysis (ASO). Data from the essential hypertensive and control subjects were statistically analysed by the Student's t-test and chi2-test. The age- and gender-matching of the groups were accurate. The case group and the control group were in Hardy-Weinberg equilibrium at this locus (cases, P=0.313; control subjects, P=0.457). There were nine alleles among the case and control groups, and the allele frequencies were found to be significantly different between cases and controls (chi2=25.701, P<0.001). The genotype frequencies were also significantly different (chi2=70.100, P<0.001) between these two groups. In conclusion, there are polymorphisms in the regulatory region of human tissue kallikrein gene in the Chinese Han people. Differences in both allele frequencies and genotype frequencies between these two groups have provided evidence towards the association of hypertension with the polymorphisms in this studied site.
