We studied the relationship between polymorphisms rs1800629 (-308G>A), rs28362491 (-94ins>del), and rs3834129 (-652ins>del) in the promoter regions of TNFA, NFKB1, and CASP8 genes, respectively, encoding TNF-α, nuclear transcription factor κB1 (NF-κB1), and caspase 8 (CASP8), and the risk and stages of chronic lymphocytic leukemia in ethnic Russians, residents of the Vyatka region of Russia. Allele -308A, genotype -308AA, and -308A genotypes (-308AA/-308AG) were associated with the risk of this pathology (OR=1.64, 95%CI 1.14-2.37, p=0.007; OR=4.48, 95%CI 1.20-16.80, p=0.02, and OR=1.57, 95%CI 1.05-2.36, p=0.03). In addition, NFKB1 allele -94del and genotype -94del/del were associated with advanced stages of the disease at the time of diagnosis (OR=0.66, 95%CI 0.46-0.97, p=0.03 and OR=0.43, 95%CI 0.20-0.92, p=0.03). These data suggest that -308G>A and -94ins>del polymorphisms of genes TNFA and NFKB1, respectively, can be involved in the pathogenesis of chronic lymphocytic leukemia.
