Background: Diamond-Blackfan anemia (DBA) is an inherited bone marrow failure syndrome characterized by anemia, short stature, congenital anomalies, and cancer predisposition.

In a small patient series and in animal models, there have been hematologic responses to L-leucine with amelioration of anemia. The study
