Brief description Hypertension (high blood pressure) is the commonest chronic condition in western societies, and can lead to strokes, heart attacks and kidney failure. In a disease known as primary aldosteronism (PAL), hypertension results from the excessive production of the salt-retaining hormone, aldosterone, by the the body's adrenal glands. In some patients, this is due to the growth of an aldosterone-producing adrenal tumour. Recent work performed within the Hypertension Unit at Greenslopes Hospital and continued by these investigators within the Hypertension Unit at Princess Alexandra Hospital has shown that PAL is the commonest potentially curable form of hypertension, accounting for at least 5% and possibly 10% of patients. Several lines of evidence accumulated by these investigators, including the detection of a new familial variety of PAL (Familial Hyperaldosteronism Type II or FH-II), suggest that PAL is a genetic disorder. The study sets out to locate the genetic defect causing PAL by comparing genetic material collected from affected members of these families with that from non-affected members, and by comparing genes from patients with PAL with those of unrelated, unaffected individuals. Once the genetics of this condition is understood, affected persons can be detected early in life, and even at birth, and the ill-effects of their developing conditions prevented.
