It has been shown that the blood lipid profile of OSAHS patients is abnormal, manifesting as a significant increase in triglyceride (TG), total cholesterol (CHOL), very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), apolipoprotein B (ApoB), and lipoprotein a (Lpa) in serum, while high-density lipoprotein (HDL) and apolipoprotein A (ApoA) levels decrease. The gene discussed is APOB; the disease is obstructive sleep apnea syndrome.
