Angiotensinogen Met235-->Thr polymorphism in a London normotensive and hypertensive black and white population

We describe angiotensinogen gene (AGT) polymorphic frequencies in different ethnic groups in London, both normotensive and hypertensive. The methodology is a recently described direct PCR technique. Results show that there is a marked difference in T-235 frequency between ethnic groups. However, there was no apparent association of T-235 with hypertension.
