Paternal smoking, genetic polymorphisms in CYP1A1 and childhood leukemia risk.

ABSTRACT: We conducted a case-control study to evaluate the association between paternal smoking and childhood leukemia and to evaluate potential modification by polymorphisms in CYP1A1. Histologically confirmed childhood leukemia cases (n=164) and non-cancer controls (n=164) were recruited from three teaching hospitals in Seoul, Korea. Five single nucleotide polymorphisms in CYP1A1 (-17961T>C, -9893G>A, I462V, 1188C>T (*2A), and 11599C>G) were genotyped and haplotypes were estimated by the expectation-maximization method. We also conducted a meta-analysis of 12 studies that have reported the association between paternal smoking and childhood leukemia risk. Paternal smoking at home was associated with all leukemias (OR=1.8, 95% CI=1.1-2.8) and acute lymphoblastic leukemia (ALL) (2.0, 1.2-3.4). An in
