Clinical Significance
Vitamin B12, also referred to as cobalamin, is a complex organometallic compound in which a cobalt atom is situated within a corrin
ring. It is a water-soluble vitamin which is synthesized by microorganisms. The disease is historically called “pernicious anemia”,
even though many patients present with mainly neurologic manifestations. Examples of other causes for vitamin B12
deficiency are malabsorption due to gastrectomy, inflammatory bowel disease or dietary deficiency, e.g. in strict
vegetarians (vegans).
