Some of the proteins that were identified have been implicated in well-established morbidities associated with OSA, such as coronary artery disease (PLAT, APOB, APOA1, APOE, PCSK9, LPA), lipid metabolism disorder (APOC3, APOB, APOA1, APOE, LCAT, PCSK9, LDLR), vascular disease (PLAT, SERPINE1, APOB, APOA1, APOE, PCSK9, LPA), atherosclerosis (APOB, APOA1, APOE, LPA), and neurodegenerative disease (APOE, SORL1, APP, BACE1, MAPT, TREM2, VLDLR). Here, PCSK9 is linked to Disorder of lipid metabolism.
