However, in the study by Cooley et al., 2010 [1], which included 1409 patients with AML or acute lymphoblastic leukemia (ALL) undergoing unmanipulated allogeneic HSCT, donor KIR B haplotype status was not associated with differences in NRM, acute GvHD (aGvHD), or cGvHD. The gene discussed is KIR3DL1; the disease is acute myeloid leukemia.
