Apolipoprotein B-100 and Apolipoprotein(a) were crucial for distinguishing the control group, while the levels of Alpha-2-macroglobulin, Apolipoprotein A-IV, Adiponectin, Complement C5, Apolipoprotein D, Alpha-1B-glycoprotein, and Serum albumin appeared to be most important for distinguishing IUGR (Figure 1). The gene discussed is ALB; the disease is fetal growth restriction.
