Furthermore, the second strongest effect was found between TP53 (rs17878362) and NFKB1 (rs28362491), with information gain values of 0.70%, and between TP53 (rs17878362) and UCP2 (INDEL 45-bp), with information gain values of 0.50%, which were SNPs associated with an increased risk for NSCLC. This evidence concerns the gene NFKB1 and non-small cell lung carcinoma.
