In the FMF in attack and FMF in remission groups, there were significant correlations between G-CSF and IL-6 (r = 0.463, P < 0.001), IL-6 and IL-12p40 (r = 0.282, P = 0.040), IL-10 and IL-6 (r = 0.531, P < 0.001), IL-10 and IL-12p40 (r = 0.731, P < 0.001), IL-10 and G-CSF (r = 0.494, P = 0.047), IFN-γ and IL-12p40 (r = 0.457, P < 0.001), IFN-γ and G-CSF (r = 0.276, P = 0.012), and IFN-γ and IL-6 (r = 0.356, P = 0.0010). The gene discussed is IL6; the disease is familial Mediterranean fever.
