Abstract

An HLA-DQA1 sequence-based typing method reliant upon group-specific amplification to achieve an unambiguous second-field DQA1 typing assignment is presented. Method validation, using 51 reference DNA samples covering 21 different DQA1 alleles, showed 100% concordance with the reference types. This typing strategy has several important uses including identifying DQA1 mismatches in kidney donor/recipient pairs to inform patient DQ antibody assignments.
