Allele and haplotype frequencies in patients with hematopoietic stemcell transplantation in National Children’s Hospital

HLA (Human Leukocyte Antigen) gene is located on chromosome 6’s short arm, including several loci. HLA genotyping is necessary for transplantation, especially in hematopoietic stem cell transplantation. A crosssectional study to determine the frequency of HLA-A, HLA-B, and HLA-DRB1 alleles of 122 patients admitted to the National Children’s Hospital for Hematopoietic stem cell transplantation from the year between 2010 and 2020.
