Introduction

Cobalamin, also known as vitamin B12, is a water-soluble vitamin that is crucial for the normal function of the gastrointestinal, dermatologic, immunologic, neuropsychiatric and hematopoietic systems. The vitamin is essential and must be supplied by our diet. Deficiency of cobalamin may be due to insufficient dietary intake, compromised gastrointestinal transport or due to inborn errors of cobalamin carriage or metabolism. We report on an infant who presented with bi- and trilineage cytopenia, fever, vomiting, diarrhea and failure to thrive. The patient was diagnosed with transcobalamin II deficiency, a defect in the blood transport and cellular uptake of cobalamin.
