Abstract

Aim: The present study was conducted to determine the effect of FOXP3 single nucleotide polymorphisms (SNPs) on clinical outcomes in CsA-treated renal transplant patients.

Methods: A total of 166 renal transplant patients with at least 5years of follow-up were included. SNPs of FOXP3 gene (rs3761547, rs3761548, rs3761549, rs2232365 and rs2280883) were detected by Taqman probe technique. The associations of SNPs with acute rejection, CsA-induced nephrotoxicity, pneumonia and post-transplantation estimated glomerular filtration rate (eGFR) were explored.

Results: Patients with rs3761549 T/TT genotype showed a more rapid decline in the eGFR level during the 5years following transplantation than those with the C/CC genotype (24.0% vs. 6.3%, P=0.004). All the SNPs and site-site interaction were not related to the occurrence of acute rejection, nephrotoxicity, and pneumonia.

Conclusions: FOXP3 rs3761549 was significantly correlated with the renal allograft function. It could be used to predict and improve the outcome of renal transplant patients taking CsA as an immunosuppressant.
