No Association of the Human Y Chromosome with Blood Pressure in Korean Male Population

No Association of the Human Y Chromosome with Blood Pressure in Korean Male Population

It has been reported that the genetic variations in the Y chromosome has influence the blood pressure in some Caucasian male populations, but the effect in non-Caucasian population is unclear. In the present study, we examined the relationship between blood pressure and a HindIII RFLP of Y chromosome in 152 unrelated male individuals of ethnically homogeneous Korean origin. There were no significant differences in systolic and diastolic blood pressures between genotype groups, respectively. However, the frequency of A genotype in Korean population was much higher than those of Caucasian populations (P＜0.05). Therefore, the results of this study will con-tribute the better understanding the genetic characteristics of Y chromosome in Korean population.
