Funded Activity Summary

High blood pressure affects 1 in 5 Australian adults and is a leading cause of mortality and morbidity from heart attack and stroke. The condition tends to run in families and genetic predisposition, in the face of environmental factors, leads to the elevation in blood pressure. My Lab has demonstrated the capacity of a cohort of affected hypertensive sibships we have collected to find loci for essential hypertension at a level that has achieved genome-wide statistical significance and has been published in a leading molecular genetics journal. Moreover, this previous work, which included fine-mapping after finding a suggestive locus following a scan of chromosome 1, not only demonstrated significant linkage, but also went on to compare gene markers between a different cohort of (unrelated) hypertensive subjects with 2 affected parents (and early-onset, moderate to severe hypertension) and control normotensive matched subjects with unaffected parents, to identify a likely candidate gene. This same approach will be used to complete the rest of the genome. The discovery of all of the genes for essential hypertension will be an important prelude to: (1) developing new, more effective treatments, since the gene products responsible will be able to be targetted by novel therapeutics, (2) genotyping individuals early in life in order to advise them what their risk is, and thus allow couselling about lifestyle modification, (3) more logically apply existing treatment strategies according to the volume-neural-vasoconstrctor component of the contribution to high blood pressure.
