The main factors influencing the presence of MAFLD were obesity (increased BMI), visceral adiposity (increased waist circumference), poor glycemic control (increased HbA1c), increased liver enzymes (ALT, AST, GGT), lower albumin levels, and dyslipidemia (TG, LDL, HDL); all of them had statistically significant odds ratios for the diagnosis of MAFLD. The gene discussed is GPT; the disease is obesity due to melanocortin 4 receptor deficiency.
