PG - 301-12 AB - We have developed a strategy for five-locus human leukocyte antigen (HLA) typing of hematopoeitic stem cell (HSC) donors using the polymerase chain reaction with sequence-specific primers (PCR-SSP). The PCR-SSP method is robust, reproducible, and accurate. New PCR-SSP mixtures can be added as required and all reactions are carried out under the same conditions, which can easily be applied to the typing of other loci, e.g., ABO blood groups. Initially, 127 PCR-SSP reactions were used to detect simultaneously HLA-A, -B, -C, -DRB1/3/4/5, and DQB1 alleles, differentiated generally to the level of the first two digits of the allele name, essentially equivalent to the serological split specificity. Approximately 40% of subjects were tested against a further 29 HLA-A, -B SSP mixtures to exclude rare alleles and unambiguously assign a two-digit HLA allele family. This gave an overall typing resolution equivalent to or greater than the split specificity level and covered all HLA-A, -B, -C, -DRBland DQB1 alleles listed in the WHO's Nomenclature for Factors of the HLA System, 2000. The Welsh Bone Marrow Donor Registry has used this strategy to HLA type over 35,000 HSC donors over 9 years. Comprehensive and accurate five-locus HLA typing allows confident and rapid identification of potential matched HSC donors for patients requiring stem cell transplantation generally without the need for typing additional loci. This allows resources to be focused directly on allele level typing of DRB1 and other loci. This strategy decreases overall donor work-up time, which is a major benefit to patients.
