Zinc deficiency in chronic liver diseases arises from a combination of factors, including a reduced capacity to synthesize albumin, malabsorption of zinc from the intestine, and an elevated excretion of zinc in the urine (Himoto et al. 2020; Ozeki et al. 2020; Grüngreiff et al. 2016; Fathi et al. 2020). The gene discussed is ALB; the disease is Zinc deficiency.
