Angiotensin I-converting enzyme gene polymorphism in two ethnic groups living in Brazil's southern region: association with age.

Background: Several studies have been published on the association between ACE (angiotensin I-converting enzyme) polymorphism and longevity. However, the results are controversial.

Methods: We analyzed the association between ACE polymorphism and age in two different ethnic populations: a population originating from different European countries (Gaucha Population, GP) and a population originating from Japan (JP).
