This proposal intends to bridge a gap between the science and practice of human leukocyte antigen (HLA) compatibility assessments and the realities of computer programming. Policy approved by the OPTN/UNOS Board of Directors in November 2014 requires HLA typing for HLA-DQA1 for deceased donors to be reported to the OPTN, and requires UNOS to change UNet^SM programming to allow transplant programs to report DQA1 as an unacceptable antigen. This proposal adds an HLA DQA1 equivalency table to policy that identifies the relationship between parent antigens and corresponding allelic subtypes. The addition of the table allows UNOS staff to program data entry for DQA1 unacceptable antigens/alleles, removing concerns about patient safety due to human error and incorrect data entry.
