Veterans taking part in massive DNA project

PALO ALTO, Calif. (KGO) — Bay Area veterans are answering the call to help with a massive research project and when it is up and running, it could provide new answers for some difficult-to-treat conditions.
Marine Corps veteran Andrew Peters says he was one of the lucky ones. He returned from Iraq with no major injuries but now, eight years later, he is volunteering for a different kind of mission. He is donating his DNA as a part of a massive project being launched by the VA. Its goal is to assemble one of the largest genetic databases ever created.
