Transcobalamin II deficiency

Transcobalamin deficiency is a disorder that impairs the transport of cobalamin (also known as vitamin B12) within the body. Cobalamin is obtained from the diet; this vitamin is found in animal products such as meat, eggs, and shellfish. An inability to transport cobalamin within the body results in cells that lack cobalamin, which they need for many functions including cell growth and division (proliferation) and DNA production. The absence of cobalamin leads to impaired growth, a shortage of blood cells, and many other signs and symptoms that usually become apparent within the first weeks or months of life.
