Recent studies have identified a genetic variant rs641738 near two genes encoding membrane bound <i>O</i>-acyltransferase domain-containing 7 (<i>MBOAT7</i>) and transmembrane channel-like 4 (<i>TMC4</i>) that associate with increased risk of non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcohol-related cirrhosis, and liver fibrosis in those infected with viral hepatitis (Buch et al., 2015; Mancina et al., 2016; Luukkonen et al., 2016; Thabet et al., 2016; Viitasalo et al., 2016; Krawczyk et al., 2017; Thabet et al., 2017).
