Complications of Fanconi anemia include the development of liver tumors and other cancers [40]; Fcgrt gene (Fc receptor, IgG, alpha chain transporter) codes for hepatic FcRn regulate albumin homeostasis and susceptibility to liver injury enhancing sensitivity to albumin bound hepatotoxins [41]; Fgf21 (fibroblast growth factor 21) is a novel biomarker for nonalcoholic fatty liver disease (NAFLD) in humans and limits ethanol-associated hepatotoxicity in mice [42]; and Saa1 (serum amyloid A1) is an evolutionary highly conserved proinflammatory acute phase protein. The gene discussed is FGF21; the disease is Fanconi anemia.
