Based on the genotype of SNVs that were associated with risk for CML (ABCB1 rs1045642 TT, ABCG2 rs2231142 CC, and SLC22A5 rs274558 AA and rs2631365 TT), we analysed the risk of CML development according to the number of risk genotypes (Table 3). The gene discussed is ABCG2; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
