PRS Center for Admixed Populations and Health Equity (CAPE) - Project Summary/Abstract

Polygenic risk scores (PRS), that aggregate risk across common variants in the genome, have emerged as a powerful tool towards implementing genomic medicine. Unfortunately, the vast majority of genomic data from which current PRS are estimated is coming from European ancestry individuals, thus prohibiting the implementation of PRS for non-European individuals.

To address this gap, multiple large-scale genomic studies are currently performed in non-European individuals. Of particular interest are individuals with recent ancestry from multiple continental sources such as African Americans and/or Hispanic Americans whose genomes are a mosaic of segments of various ancestries. Such diversity in genetic ancestry raises unique challenges in the equitable PRS development as the accuracy and bias of existing PRS varies across genomic ancestries.

Unlike existing paradigms that largely view genetic ancestry as a confounder in PRS studies, we aim to fully integrate population genetics of the admixture process to yield admixture-PRS that provide equitable accuracies for all individuals irrespective of genetic ancestries. We will integrate data of over 230,000 admixed individuals across five diverse medical systems including UCLA, Mt Sinai, Colorado to develop, calibrate, and benchmark PRS for admixed individuals.

NHGRI SUPPORTS THE DEVELOPMENT OF RESOURCES AND TECHNOLOGIES THAT WILL ACCELERATE GENOME RESEARCH AND ITS APPLICATION TO HUMAN HEALTH AND GENOMIC MEDICINE. A CRITICAL PART OF THE NHGRI MISSION CONTINUES TO BE THE STUDY OF THE ETHICAL, LEGAL AND SOCIAL IMPLICATIONS (ELSI) OF GENOME RESEARCH. NHGRI ALSO SUPPORTS THE TRAINING AND CAREER DEVELOPMENT OF INVESTIGATORS AND THE DISSEMINATION OF GENOME INFORMATION TO THE PUBLIC AND TO HEALTH PROFESSIONALS. THE SMALL BUSINESS INNOVATION RESEARCH (SBIR) PROGRAM IS USED TO INCREASE PRIVATE SECTOR COMMERCIALIZATION OF INNOVATIONS DERIVED FROM FEDERAL RESEARCH AND DEVELOPMENT, TO INCREASE SMALL BUSINESS PARTICIPATION IN FEDERAL RESEARCH AND DEVELOPMENT, AND TO FOSTER AND ENCOURAGE PARTICIPATION OF SOCIALLY AND ECONOMICALLY DISADVANTAGED SMALL BUSINESS CONCERNS AND WOMEN-OWNED SMALL BUSINESS CONCERNS IN TECHNOLOGICAL INNOVATION. THE SMALL BUSINESS TECHNOLOGY TRANSFER (STTR) PROGRAM IS USED TO FOSTER SCIENTIFIC AND TECHNOLOGICAL INNOVATION THROUGH COOPERATIVE RESEARCH AND DEVELOPMENT CARRIED OUT BETWEEN SMALL BUSINESS CONCERNS AND RESEARCH INSTITUTIONS, TO FOSTER TECHNOLOGY TRANSFER BETWEEN SMALL BUSINESS CONCERNS AND RESEARCH INSTITUTIONS, TO INCREASE PRIVATE SECTOR COMMERCIALIZATION OF INNOVATIONS DERIVED FROM FEDERAL RESEARCH AND DEVELOPMENT, AND TO FOSTER AND ENCOURAGE PARTICIPATION OF SOCIALLY AND ECONOMICALLY DISADVANTAGED SMALL BUSINESS CONCERNS AND WOMEN-OWNED SMALL BUSINESS CONCERNS IN TECHNOLOGICAL INNOVATION.
