The role of HLA genes in pharmacogenomics: unravelling HLA associated adverse drug reactions

Patricia T Illing, Anthony W Purcell, James McCluskey



Genetic polymorphism in the genes encoding the human leukocyte antigen (HLA) molecules enables presentation of a wide range peptide ligands thus maximising immune surveillance of pathogens. A consequence of the diversification of the HLA Ag-binding pocket is the enhanced opportunity for off-target binding of small drugs by HLA molecules, with subsequent immune reactivity. These potential off-target interactions are 'set up' to generate T cell-mediated adverse drug reactions even though the precise mechanisms of most HLA-drug interactions are still poorly understood. The association between abacavir hypersensitivity syndrome and HLA-B*57:01 is one exception that has been resolved at a molecul..
