The clinical relevance of minor histocompatibility antigens in transplantation is disputed. High-throughput approaches are now being used to investigate the role of genome-wide genetic incompatibility in transplant outcomes. A recent study reports that donor and recipient mismatch at the LIMS1 locus is associated with an increased risk of acute rejection.
