DeCODE scientists discover common SNPs that increase number of CPD and risk of lung c

[News]

Cigarette smoking is a major cause of illness and death worldwide. But it is a complex behavior, and how much people smoke, how hard they find it to quit, and the impact of long-term smoking on health varies greatly among individuals. A substantial portion of this variability is genetic. Two years ago, deCODE discovered the first common, single-letter variation in the sequence of the human genome, on chromosome 15q25, associated with nicotine addiction and risk of lung cancer.
