Interindividual HLA Evolutionary Divergence in Single HLA-Mismatched Unrelated Donor Hematopoietic Cell Transplantation for Malignant Hematological Disorders: A Report on Behalf of the Cellular Therapy and Immunobiology Working Party of the EBMT
This study demonstrates that quantifying HLA evolutionary divergence (HED) in 9/10 mismatched unrelated donor transplants reveals significant within-mismatch heterogeneity and complex, locus-specific interactions that independently predict clinical outcomes such as relapse-free survival, graft-versus-host disease, and mortality, thereby complementing conventional mismatch classification.
