We previously investigated this cohort for variants in the PNPLA3 and TM6SF2 genes to identify people at a higher risk of liver steatosis (PNPLA3) and fibrosis (TM6SF2), a condition frequently associated with obesity, diabetes, and metabolic syndrome [25]. The gene discussed is TM6SF2; the disease is obesity due to melanocortin 4 receptor deficiency.
