Megaloblastic Anemia Progressing to Severe Thrombotic Microangiopathy in Patients with Disordered Vitamin B12 Metabolism: Case Reports and Literature Review

We describe 2 children with cobalamin G disease, a disorder of vitamin B12 metabolism with normal serum B12 levels. They presented with megaloblastic anemia progressing rapidly to severe thrombotic microangiopathy.
