Vascular Disease Discovery Protocol

The NIH provides a unique opportunity for research scientists to participate in the bench-to-bedside process, which is essential for the full implementation of translational medicine programs. The study of rare monogenetic and undiagnosed diseases is a complex bedside-to-bench-to-bedside endeavor. Recent studies show that rare genetic variants are more likely than common variants to have deleterious effects on protein structure, function, and/or expression, possibly leading to clinically relevant events. Studies of large patient populations offer the opportunity to identify rare genetic variants underlying human disease and will have impactful implications for human health. We propose to characterize the etiology and natural history of rare and orphan diseases with vascular phenotypes. We will also study rare genetic modifiers and identify novel disease mechanisms contributing to common vascular diseases. Subsequent disease-related protocols may be developed based on findings from subjects enrolled in this protocol for further intensive natural history studies and potential innovative therapeutic studies. In addition to its role in investigating individuals who are of interest to the Translational Vascular Medicine Branch (TVMB) of the NHLBI, this protocol can provide a possible avenue for admitting subjects from other NIH programs, such as the NIH Undiagnosed Diseases Program, the Center for Human Immunology Trans-institute program or other NIH protocols where subjects exhibit vascular phenotypes.
