APOC3 and obesity due to melanocortin 4 receptor deficiency: Additionally, we also observed that overweight and obesity among ALL survivors were positively correlated with the levels of Apo-C3, apolipoprotein H (Apo-H), Apo-J, and CRP (Apo-C3: r = 0.60; Apo-H: r = 0.49; Apo-J: r = 0.41; CRP: r = 0.47; p < 0.05; ).
