In Table 2, regarding the correlation between the three adverse reactions of HSCT and the candidate SNPs in ALL group, the rs209132 of TRIM27 gene was associated with the risk of CMV infection (p = 0.021), and the rs213210 of the RING1 gene was related to the risk of GVHD grade 3–4 (p = 0.003) in donor group. This evidence concerns the gene RING1 and acute lymphoblastic leukemia.
