Health Disparities in Genomics and Genetics

Disparities or inequities in health refer to sociodemographic group differences in the distribution of disease, health outcomes, or access to health care [1]. In order to eliminate health disparities, more efforts are needed to address social issues directly contributing to the healthy inequities observed across racial and ethnic groups. With broad support from many federal agencies, alleviating health disparities in the United States remains a goal of Healthy People 2010 [2]. However, genetic research also has a significant role to play in alleviating and understanding disparities. With tremendous advances in technology and increased investigation into human genetic variations, genomics is poised to play a valuable role in bolstering efforts to find new treatments and preventions for chronic conditions that disparately affect certain ethnic groups. The recent statement regarding the future of genomics from the National Human Genome Research Institute (NHGRI) [3] indicated that the need to develop genome-based tools to address health disparities remains a “grand challenge”. The statement acknowledges that social and economic factors contribute significantly to disparities but nevertheless assert the need for extensive research to better understand the contribution of genetics.
