The Department of Veterans Affairs (VA) launched a new genomic research tool designed to help VA researchers learn more about how conditions such as cancer, diabetes, and heart disease affect veterans from minority backgrounds, according to a news release.
The laboratory tool, known as the Ethnic Focused genotyping array or DNA chip, will test more than 750,000 genetic variants, including over 300,000 that are more common in minority populations.
The tool was custom-built for VA’s Million Veteran Program (MVP), which studies how genes affect health, the VA said.
“This is potentially a game changer in medical research for Black and Hispanic Veterans and other members of minority ethnic and racial groups,” said Acting VA Under Secretary for Health Richard A. Stone, MD.
A genotyping chip is a piece of glass about the size of postage stamp containing hundreds of thousands of tiny bits of synthetic DNA. These DNA probes allow researchers to identify genetic variants in the DNA of research volunteers.
The probes also associate certain health traits — like increased risk for a disease or unfavorable reactions to a drug with specific genetic patterns. This can lead to new treatment approaches for patients with those gene profiles.
With more than 830,000 veteran volunteers currently enrolled, MVP is one of the largest health and genetic databases in the world, according to the VA.
Currently, over 30 ongoing studies based on MVP data are examining conditions ranging from heart disease and diabetes to post-traumatic stress disorder, schizophrenia and suicide risk. In recent months, researchers have begun using MVP data to study the impacts of COVID-19 on Veterans.
