There were no significantassociations between MDM2 (rs2279744) polymorphisms andlung cancer with regard to G allele vs. T allele: OR = 0.86,95 % CI 0.71–1.03, p = 0.1; homozygote model: OR = 0.86,95 % CI 0.71–1.03, p = 0.1; dominant model: OR = 0.90, 95 %CI 0.79–1.02, p = 0.5 and recessive model: OR = 1.10, 95 %CI 0.94–1.22, p = 0.276. This evidence concerns the gene MDM2 and cancer.
