An Infant With Imersland-Grasbeck Syndrome

The Imersland-Grasbeck Syndrome (IGS) is a rare inherited disorder characterized by megaloblastic anemia due to a selective Vitamin B-12 malabsorption in association with mild proteinuria. This syndrome can be diagnosed and treated easily. Herein, we describe an infant with IGS as a rare etiology of growth retardation with diarrhea, vomiting and therapy-resistant proteinuria.
