Single nucleotide polymorphisms within HLA region are associated with the outcomes of unrelated cord blood transplantation

Abstract Cord blood transplantation (CBT) provides a treatment scheme for hematologic diseases and leukemia in both children and adults. However, adverse reactions and transplantation-related death may still occur in patients receiving CBT even when donor and recipient have fully matched HLA in high...

However, adverse reactions and transplantation-related death may still occur in patients receiving CBT even when donor and recipient have fully matched HLA in high-resolution HLA typing analysis. Single nucleotide polymorphisms (SNPs) of HLA-related and unrelated genes are known to associate with disease status of patients with unrelated stem cell transplantation. In this study, the genomic regions ranging from 500 base pairs upstream to 500 base pairs downstream of the eight SNPs that were reported as transplantation determinants by Petersdorf et al. were analyzed to evaluate whether genetic variants were associated with the survival status of patients, and the risk for severe (grades 3–4) graft-versus-host disease (GVHD) or cytomegalovirus (CMV) infection/reactivation. The analyses were performed in the mode of recipient genotype, donor genotype, and recipient-donor mismatching, respectively. By analysis of sixty-five patients and their HLA-matched unrelated donors, we found that five SNPs were associated with patient survival which included the recipient genotype with SNPs of rs107822 in the RING1 gene, and rs2070120, rs17220087 and rs17213693 in the HLA-DOB gene; and the recipient-donor mismatching with SNPs of rs9282369 in HLA-DOA gene, and rs2070120, rs17220087 and rs17213693 in the HLA-DOB gene. Five SNPs were associated with the risk for severe GVHD which included the donor genotype with SNPs of rs213210 and rs2523675; the recipient genotype with SNPs of rs9281491 in the HCP5 gene; and the recipient-donor mismatching with SNPs of rs209130 in the TRIM27 gene, and rs986522 in the COL11A2 gene. Six SNPs were related to the risk for CMV infection/reactivation which included the donor genotype with SNPs of rs435766, rs380924, and rs2523957; and the recipient-donor mismatching with SNPs of rs2070120, rs17220087, and rs17213693 in the HLA-DOB gene; and rs435766 and rs380924 in the MICD gene.
