RESUMEN
There are wide individual differences in pharmacokinetic parameters of mycophenolate mofetil [MMF] among transplanted patients. Some studies have shown that single nucleotide polymorphisms [SNPs] of the Uridine Diphosphate Glucuronosyl Transferase1A9 [UGT1A9] are responsible for these differences in early days after transplantation. Therefore it was decided to evaluate the influence of UGT polymorphism on MMF pharmacokinetics among stable Iranian transplant patients. This was a cross sectional study from March 2008 through December 2008 in Imam Khomeini Hospital affiliated to the Tehran University of Medical Sciences in Iran. Blood samples were taken from 40 de novo stable Iranian renal transplant patients taking 2 g MMF daily with Sr[Cr]
