ROCHESTER, Minn., March 23 (UPI) — U.S. medical geneticists say they’ve linked a gene to lung cancer development in people called “never smokers.”

The study — co-led by the Mayo Clinic, Harvard University, the University of California-Los Angeles and the M.D. Anderson Cancer Center — found about 30 percent of never smoker patients who developed lung cancer had the same uncommon variant residing in a gene known as GPC5.

A never smoker is defined as a person who has smoked fewer than 100 cigarettes during his or her lifetime.
