However, there was no correlation between anti-Axl IgG and SLEDAI score, neither did anti-Mertk IgG (all p > 0.05, Supplementary Figures 2C and 2D), indicating that the high levels of anti-Axl and anti-Mertk antibodies might not be associated with SLE disease activity. The gene discussed is MERTK; the disease is systemic lupus erythematosus.
