Since FGFR1 expression was reported to be positively correlated with FGF21 expression [25,26], the eQTL result was in line with the fact that serum level as well as hepatic expression level of FGF21 were positively associated with the intrahepatic steatosis grade and hepatic triglyceride levels, respectively [25,26,27]. The gene discussed is FGF21; the disease is steatosis.
