- Association of Donor Vascular Endothelial Growth Factor Gene Polymorphism With Acute Renal Allograft Rejection Narayan Prasad Brijesh Yadav Mansi Bhatt Ranjeet Chauhan Vinita Agrawal Clinical Transplantation AbstractBackgroundRecipient's VEGF‐A polymorphisms have been reported to be associated with the risk of acute allograft rejection. However, an association of the donor's VEGF‐A gene polymorphism with rejection remained unelucidated till now.MethodsIn this study, VEGF‐A gene SNPs at nine loci were analyzed in 160 kidney donors and recipients with rejection (rejectors, n = 80) and without rejection (non‐rejectors, n = 80). Blood VEGF‐A mRNA, plasma VEGF level, and intragraft VEGF expression were also analyzed by RT‐PCR, ELISA, and immunohistochemistry, respectively.ResultsOn comparing between the donor and rejectors, the polymorphic genotypes of VEGF –634 C>G [GG genotype, p < 0.0001; OR (95% CI) = 17.74 (5.16–60.96)]; VEGF –1154 G>A [AG genotype, p < 0.0001, OR (95% CI) = 16.07 (3.68–70.15)]; VEGF +936 C>T [CT genotype, p < 0.0001, OR (95% CI) = 178.64 (23.28–1370.9), and TT genotype, p < 0.0001; OR (95% CI) = 3149 (278.91–35 553)]; VEGF –1455 T>C [CC genotype, p value = 0.0464, OR (95% CI) = 3.13 (1.07–9.10)]; VEGF –2578 C>A [CA genotype, p = 0.0426, OR (95% CI) = 4.62 (1.03–20.59), and AA genotype, p value < 0.0001, OR (95% CI) = 21.89 (4.94–97.04)]; VEGF –2549 18 bp Insertion/Deletion [ID genotype, p value < 0.0001, OR (95% CI) = 27.27 (3.61–205.73) and DD genotype, p value < 0.0001, OR (95% CI) = 25.18 (3.30–191.89) were significantly associated with acute rejection risk. On comparing rejectors versus non‐rejectors, GA genotype of VEGF –1190 G>A and TC genotype of VEGF –1455 T>C were associated with the risk of rejection. On comparing donor VEGF between rejectors and non‐rejectors, CG genotype of VEGF –634 C>G, AG of VEGF –1154 G>A; GA of VEGF –1190 G>A were associated with rejection. The blood VEGF‐A mRNA and plasma VEGF levels were higher in the rejectors group compared to non‐rejectors.ConclusionsBesides the recipient's VEGF SNPS, the donor's VEGF SNPs are also associated with the risk of acute rejection and may be closely monitored in evaluation to determine the risk of rejection. 10.1111/ctr.15475 http://onlinelibrary.wiley.com/termsAndConditions#vor
