Historic findings could boost precision medicine, reduce health disparities

What

Researchers supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, announced the publication of a groundbreaking study which analyzed more than 53,000 whole genomes, primarily from minority populations. The study, which appears in the Feb. 10 online issue of the journal Nature, examines one of the largest and most diverse data sets of high-quality whole genome sequencing—a person’s complete set of DNA. The genetic data could shed new light on how heart, lung, blood, and sleep disorders impact people with diverse racial and ethnic backgrounds, who often are underrepresented in genetic studies.

The whole genomes used in the study are based on data from participants in the NHLBI’s Trans-Omics for Precision Medicine Program (TOPMed). Researchers there hope this data will one day lead to treatments tailor-made to individual patients, as well as shed light on racial and ethnic health disparities. Among its many findings, the current study: 

  • Identified 400 million genetic variants, more than 78% of which had not been described before
  • Produced the best quality genotype data available for people with African ancestry, who showed the highest genetic variability of the groups studied
  • Provided new insights into certain gene variants that adversely affect the metabolism of prescription drugs and whose biological effects may vary by race and ethnic group

Who

Cashell Jaquish, Ph.D., a genetic epidemiologist and program officer for TOPMed, Division of Cardiovascular Sciences, NHLBI, is available to comment on the findings and implications of this research. She is a corresponding author on the Nature paper.
