Regarding the frequency of genotypes/alleles of the polymorphisms of the cytokines TGF-β and IFN-γ, we observed a higher prevalence expression of C/C from the TGF-β and T/A from the IFN-γ genotypes in both groups (AKI and No AKI patients) (Table 3). The gene discussed is IFNG; the disease is acute kidney injury.
