IFNG and chronic myelogenous leukemia, BCR-ABL1 positive: Our results suggested that rs2430561 in IFN-γ on chromosome 12q24 contributes to susceptibility to CML and CLL based on traditional genotyping methods, and these results have motivated us to carry out a GWAS focus on the SNPs on chromosome 12 to discover novel susceptibility loci for leukemia in the future.
