A PCR-based strategy termed DHDA has recently been developed which reveals DQA1 and DQB1 allelic polymorphism through gel retardation following electrophoresis. This HLA-typing strategy improves the efficiency of identifying previously undetected DNA sequence polymorphisms. DHDA has been utilized to perform DQA1 genotypic analysis in non-Caucasian populations and has resulted in the identification of a novel...
