Abstract
A total of 84 individuals were DP typed in parallel with the restriction fragment length polymorphisms (RFLP) analysis and the primed lymphocyte test (PLT). Whereas 80% of the cases gave concordant results, the other 20% showed discrepancies for one of the two alleles carried by the typed individuals. Oligotyping, PCR-RFLP and sequencing confirmed the results found by PLT. The 20% discordant results obtained with RFLP led us to conclude that RFLP typing cannot replace PLT typing. From a more general point of view, the RFLP analysis revealed the DP region to be more complex than expected since for each given PLT DP defined specificity, more than one RFLP DP haplotype could be determined. These were possibly induced by crossing-overs or gene conversion events. Human Immunology 34, 39–46 (1992)
