What are the signs and symptoms of congenital dyserythropoietic anemia type II?

The signs and symptoms of CDA II include jaundice, gallstones and an enlarged liver and spleen. This condition also causes the body to absorb too much iron, which builds up and can damage tissues and organs. In particular, iron overload can lead to an abnormal heart rhythm (arrhythmia), congestive heart failure, diabetes, and chronic liver disease (cirrhosis). Rarely, people with CDA type II have mediastinal tumors. During pregnancy and other special circumstances (such as anemic crisis, major surgery and infections), blood transfusions may be necessary.[1][2]
