Gene mutation tied to lung cancer

Scientists have found a gene on chromosome 19 that’s often mutated in people with lung adenocarcinoma, a kind of cancer responsible for about half of all lung tumors.
The gene, called LKB1/STK11, was mutated in 8 of 24 lung adenocarcinoma tumors that the researchers analyzed but was normal in all 17 samples of other types of lung tumors, says Montserrat Snchez-Cespedes, who was part of the team that made the discovery at Johns Hopkins University Medical Institutions in Baltimore.
