Recent studies suggest that FGF19, FGF21, and FGF23 are associated with alcohol and alcohol-related disorders (Schumann et al., 2016; Quintero-Platt et al., 2017; Brandl et al., 2018; Gonzalez-Reimers et al., 2018; Epperlein et al., 2021). The gene discussed is FGF21; the disease is alcohol-related disorders.
