PG - 514-9 LID - 10.1111/j.1399-0039.2009.01375.x [doi] AB - An association between human leukocyte antigen (HLA) molecules and the incidence of various diseases has been recognized for years. Molecules of the HLA system also exert an important role on the clinical outcome after transplantation such as stem cell transplantation. The conventional HLA typing method is sequence based typing (SBT) which is reliable but laborious. The goal of this study was to develop a high-throughput Taqman assay to screen large panels for HLA-E alleles. Two functional HLA-E alleles, *0101 and *0103, have been identified. We set up the Taqman assay with genomic DNA as template to discriminate the three HLA-E genotypes: homozygous HLA-E*0101, heterozygous *0101, *0103 and homozygous *0103. This Taqman approach was validated by the comparison of results obtained with the typing results acquired by sequenced base typing (SBT). Additional screening of a large panel showed the pronounced discriminative capacity of the Taqman assay for HLA-E allele typing. The Taqman assay is a fast, reliable and consistent HLA-E allele typing method, especially useful to screen large panels.
