African iron overload is a rare disorder described in sub-Saharan African populations and is characterized by iron overload due to excess dietary iron intake and possibly genetic factors, leading to hepatic portal fibrosis and micronodular cirrhosis.
Features include very common findings: Elevated ferritin (iron storage marker) (increased circulating ferritin concentration); and common findings: Elevated transferrin saturation, Liver scarring (fibrosis) (hepatic fibrosis), Hepatic periportal necrosis, and Viral hepatitis and others. 26 total HPO annotations.
