Incompatibility of human leukocyte antigen (HLA) alleles between donors and recipients of unrelated hematopoietic stem cell transplantation (UHSCT) increases the risk of acute graft-versus-host disease (GVHD). We evaluated the positional effect of amino acid substitutions in HLA molecules on severe acute GVHD in Korean pediatric recipients of UHSCT. All of 64 donor-recipient pairs were serologically matched for HLA-A, -B, and -DR loci. Only substitution at residue 9 resulting from an HLA-A*02 polymorphism was significantly associated with the risk of severe acute GVHD in patients (OR=7.0, P=0.033) on multivariate analysis. Recipients of this mismatched HLA also showed shortened overall survival (HR=9.7, P<0.001) and increased risk for transplant-related mortality (HR=9.1, P=0.027). Structural modeling showed that the amino acid substitution could alter the peptide preference of the ligand-binding pocket. A single amino acid substitution at position 9 was a major predictor of severe acute GVHD in Korean pediatric patients.
