Key result
The ACE DD, CYP CT, and CYP TT genotypes were significantly associated with an increased risk of hypertensive stroke in the Mongolian population (OR 3.182, 6.179, and 6.089, respectively).
Why the study?
Are specific gene polymorphisms associated with an increased risk of stroke in Mongolian patients with hypertension?

The ACE DD, CYP CT, and CYP TT genotypes are associated with an increased risk of stroke in Mongolian patients with hypertension.
May inform risk stratification in Mongolian hypertensives; hypothesis-generating and requires prospective validation.
OBJECTIVES: To identify susceptible single nucleotide polymorphisms causing prevailing essential hypertension complicating stroke in the Mongolian population. METHODS: This study was carried out at the Beijing Huada Genome Company, Beijing, and the Clinical Testing Center of Inner Mongolia Medical College, Hohhot, P.R. China from March to November 2005, and included 96 patients with hypertension (control group) with an average age of 53 +/- 11 years, and 68 patients with hypertensive stroke with an average age of 60 +/- 10 years. The gene polymorphisms were examined by the polymerase chain reaction-restriction fragment length polymorphism technique and the Sequenom system, and analyzed by multiple regression analysis. RESULTS: Logistic multiple regression analysis revealed significant differences between the groups for age and smoking. Genotypes and allele gene frequencies were not significantly different between the groups. The significant incidence risks were p = 0.011, odds ration (OR) = 3.182 for the ACE DD genotype, p = 0.038, OR = 6.179 for the CYP CT genotype, and p = 0.042, OR = 6.089 for the CYP TT genotype. All the other genotypes did not significantly correlate to hypertension and hypertensive stroke. CONCLUSION: The ACE DD, CYP CT andTT genotypes are candidates for hypertension complicating stroke in the Mongolian population. The risk of disease was lowest among the ACE II and CYP CC genotypes.

Huriletemuer et al. (2010) conducted a case-control in hypertensive stroke (n=164). ACE DD, CYP CT, and CYP TT genotypes vs. ACE II and CYP CC genotypes was evaluated on hypertensive stroke (OR 3.182, p=0.011). The ACE DD, CYP CT, and CYP TT genotypes were significantly associated with an increased risk of hypertensive stroke in the Mongolian population (OR 3.182, 6.179, and 6.089, respectively).
