We performed a specific subgroup analysis in patients with acute myeloblastic leukemia (AML), and we detected that the LAG3 rs870849 CT/TT genotype of the donor was not associated with relapse (CC: 28% vs. CT/TT: 50.5%; p: 0.310; HR 1.40, 95%CI: 0.73 – 2.69). The gene discussed is LAG3; the disease is acute myeloid leukemia.
