No significant correlations were observed in the expression levels of IFN-γ (r2 = 0.038, P = 0.408), IL-10 (r2 = 0.038, P = 0.409), IL-12p70 (r2 = 0.041, P = 0.394), IL-17A (r2 = 0.029, P = 0.475), IL-6 (r2 = 0.004, P = 0.798) and TNF-α (r2 = 0.059, P = 0.302) compared between the ELF and serum in the MD group. This evidence concerns the gene IL17A and Menkes disease.
