The National Institutes of Health (NIH) has announced a funding opportunity for the NHLBI TOPMed program, aimed at generating integrated genetic and multi-omics data to enhance the understanding of heart, lung, blood, and sleep (HLBS) disorders. This X01 Resource Access Award invites applications that utilize NHLBI-funded resources to uncover molecular mechanisms related to these disorders, transitioning from genetic mapping to a comprehensive understanding of disease pathobiology. While no direct funding will be provided, applicants are encouraged to access omics data from NIH-designated controlled-access databases, with a focus on addressing significant knowledge gaps using well-characterized biospecimens. Interested applicants must submit their proposals by October 17, 2024, and can find additional information and application guidelines at the NIH website or contact the NIH OER Webmaster at OERWebmaster03@od.nih.gov for further inquiries.
