Variations in MMP Genes Are Associated with Differences in Lung Cancer Risk

Variations in genes for a family of proteins called matrix metalloproteases (MMPs) have been suggested to play a role in lung cancer risk. A meta-analysis of several studies on MMP genes found that a particular version (or “polymorphism”) of the MMP1 gene, called MMP1-1607 1G/2G, is associated with higher susceptibility for lung cancer in Asian patients. In contrast, the MMP2-1306 C/T version of the MMP2 gene decreases lung cancer risk in Asian patients and the MMP9-1562 C/T version of the MMP9 gene decreases lung cancer risk in white patients.
