Abstract:
:Gene polymorphisms of cytotoxic T lymphocyte associated antigen 4 (CTLA4) play an influential role in the graft rejection and long-term clinical outcome of organ transplantation. We investigated the associations of five CTLA4 single nucleotide polymorphisms (SNPs) (rs733618T/C, rs4553808A/G, rs5742909C/T, rs231775G/A, rs3087243G/A) on the early acute rejection (AR) of Chinese deceased donor renal transplantation recipients. Genotyping of the CTLA4 SNPs was performed in 167 deceased donor renal transplantation recipients. Each patient underwent a 6-month follow-up observation for AR. The incidence of AR during the 6 months post-transplantation was 26.9% (45 out of 167 patients). Patients experiencing AR were found to have a higher frequency of the rs733618TT genotype and T allele (p=0.000 and p=0.002, respectively). While the haplotype CACAG was merely observed in non-AR group (corrected p=0.000), the frequency of haplotype TACGG was significantly higher in AR group than in non-AR group even after 50,000 permutation tests (corrected p=0.018). In conclusion, these polymorphisms statistically significantly associated with acute renal allograft rejection may be considered as a risk factor of AR in Chinese renal transplantation recipients except for haplotype CACAG as a protective one.
