The broad application of human genetics will progress from the study of rare mendelian traits with complete penetrance compiled over the last 3-4 decades to a large number of "common" diseases that have multi-gene etiology with variable penetrance such as non-insulin dependent diabetes mellitus and hypertension. Cardiology will probably stay at a forefront of this transformation, as cardiovascular diseases (CVD) remain the major source of morbidity and mortality in developing countries, and is fast reaching the same status in the underdeveloped countries. Furthermore, the track record of rapid adaptation of new technology and research in the field of cardiology, would give further impetus to this transition. In the midst of these dynamic currents, this proposal puts forward a research plan to initiate a genetic databank, henceforth referred to as The Genebank at Scripps Clinic Registry. This database will usher in genomic research at Scripps as we strive to stay at the forefront of cardiovascular research in the new century.
