Molecular variants of angiotensinogen (AGT) have been associated with AGT level and hypertension (HT). However, results from reported studies vary considerably between- and within-studied populations. We performed association analysis of AGT gene variants with AGT levels and HT in samples of African descent families, including 595 Nigerians and 901 African Americans. We evaluated association using haplotypes defined by a set of single-nucleotide polymorphisms selected from a previous detailed study of the gene haplotype structure. In the sample of Nigerian families, AGT haplotype H1 was associated with high plasma level. Results were not significant for blood pressure (BP) or HT. For the African-American population, we found significant association between low plasma AGT level and haplotype H7. Furthermore, we found weak associations of H1 with hypertensive status and H7 with low systolic BP. However, no significant association between H1 and high plasma level was found. We conclude that the two distantly related haplotypes, H1 and H7, are associated, but have opposite effects on the phenotypes in two populations of African origin.
