As a result, a number of studies connected the role of omentin with many disorders, such as: polycystic ovary syndrome (PCOS) [23], rheumatoid arthritis (RA) [24], metabolic dysfunction–associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD) [25], atherosclerosis [10], and Crohn’s disease (CD) [7]. Here, ITLN1 is linked to polycystic ovary syndrome.
