title: Angiotensin II type I receptor polymorphism in African Americans lower frequency of the C1166 variant.
abstract: The C1166 variant, an A to C substitution polymorphism at the 1166 position of the angiotensin II type I (AT1) receptor, has been previously associated with hypertension in Caucasians. This study determines the frequency of the C1166 variant in an African American population. Normotensive African American (n = 99) and Caucasian (n = 100) subjects were genotyped to determine the frequency of the C1166 variant. This study establishes the frequency of the C1166 variant in African Americans (0.05 +/- 0.01) and demonstrates a significantly lower frequency in African Americans compared with Caucasians (0.05 vs. 0.25, respectively, chi 2 = 30.7, p < < 0.001, 1 df).
