Four sequence variants in the 11 beta-hydroxylase (CYP11B1) gene are r
eported. One of the sequence changes occurs in exon 1 and is in linkag
e disequilibrium with a second variant in intron 3. The other two chan
ges occur at adjacent nucleotides in intron 1. The finding of easily d
emonstrable, intragenic variants will be beneficial to the study of th
e role of the CYP11B1 and the adjacent aldosterone synthase (CYP11B2)
gene in hypertensive disease.
