Plasma concentrations of sMerTK, sAxl and growth arrest-specific gene 6 protein (GAS6) according to specific genotypes. Genotypes giving significant differences in the concentration of their gene products are selected. (A) GAS6 rs8191974 (intron 8, c.834 ± 7G > A); (B) MERTK rs869016 (intron 1a, c.61 ± 2737G > A) and (C), AXL rs2304232 (intron 6 c.2169 ± 9A > G). SLE, systemic lupus erythematosus.
