Abstract: With the development of genome-wide association analysis technology, it has been widely found
that transmembrane 6 superfamily member 2 (TM6SF2) gene plays a potiental role in lipid metabolism of
liver. Recently, some studies showed that gene polymorphism of TM6SF2 E167K was associated with the
occurrence and development of non-alcoholic fatty liver disease (NAFLD) and also associated with the liver
inflammation, cirrhosis and even hepatocellular carcinoma (HCC) related to alcoholic liver disease (ALD) and
chronic hepatitis C (CHC). This article described the expression of TM6SF2 in human tissues and reviewed
recent progress in understanding the role of TM6SF2 gene polymorphism in the pathogenesis of the above
three liver diseases.
