DNA polymorphisms and linkage disequilibrium in the angiotensinogen gene.
A number of recent studies have implicated the angiotensinogen gene in the aetiology of essential hypertension in Caucasian, Japanese and African Caribbean subjects. We have genotyped 153 healthy white Caucasian subjects at a dinucleotide repeat polymorphism and seven diallelic sites in the coding or flanking regions of the angiotensinogen gene, including one polymorphism not previously studied. We have also documented patterns of linkage disequilibrium between polymorphisms. There is evidence of variation in the frequency of several mutations when compared with published results from other Caucasian control populations, possibly due to cryptic ethnic differences between these groups. This should be considered in the design and interpretation of studies of the angiotensinogen gene.
