Furthermore, results of the recent studies suggest that the genes involved in hepatic lipid synthesis (ACACA, FASN, LPL, SCD1, FADS1, and FADS2) were down-regulated over nutritional deficiency (Kaufmann et al., 2012; Laporta et al., 2014; Vailati Riboni et al., 2015). The gene discussed is FASN; the disease is nutritional deficiency disease.
