Zuber and colleagues from Paris describe a case of diabetes that developed after renal transplantation in a young, white, nonobese man. Genetic screening detected a newly described deletion in the gene encoding hepatocyte nuclear factor 1 homeobox B,HNF1B, indicating that mutations in HNF1Bmight account for some 'unexpected' cases of new-onset diabetes after transplantation. Minimization of tacrolimus exposure and withdrawal of steroids markedly reduced the patient's insulin requirement.
