Key result
A common variant in the proximal promoter of the angiotensinogen gene, an adenine instead of a guanine at position -6, is associated with essential hypertension and significantly increases basal transcription in vitro.
Why the study?
Is a nucleotide substitution in the angiotensinogen gene promoter associated with essential hypertension and altered basal transcription?
Population
Humans with essential hypertension and in vitro models
Comparison
Adenine substitution 6 bp upstream from the… vs Guanine at the same position (wild-type)

Highlights potential genetic predisposition to hypertension; hypothesis-generating for promoter variant effects in vivo.
Is a nucleotide substitution in the angiotensinogen gene promoter associated with essential hypertension and altered basal transcription?
p-value: p=2.4 x 10^-6
A specific nucleotide substitution in the angiotensinogen gene promoter is associated with essential hypertension and alters basal transcription, providing insight into genetic predispositions to the disease.
Inoue et al. (1997) studied Essential hypertension (n=547). Adenine at position -6 (A(-6)) in AGT promoter vs. Guanine at position -6 (G(-6)) was evaluated on Basal transcription rate in vitro (p=2.4 x 10^-6). A common variant in the proximal promoter of the angiotensinogen gene, an adenine instead of a guanine at position -6, is associated with essential hypertension and significantly increases basal transcription in vitro.
