When the ACE levels of the patients with and without HT, DM, hyperlipidemia, and hypertriglyceridemia were compared in the NAFLD group, the ACE level was found to be 11.94 ± 1.90 ng/mL in the subjects without HT (n = 27), 12.01 ± 1.96 ng/mL in the subjects with HT (n = 4), 10.18 ± 2.21 ng/mL in the subjects with DM (n = 4), 11.91 ± 1.90 ng/mL in the subjects without DM (n = 27). The gene discussed is ACE; the disease is diabetes mellitus.
