ABCD4 and CblF proteins responsible for hereditary vitamin B12 deficiency

Vitamin B12 is vital for cell division, the synthesis of red blood cells and the functioning of the nervous system. Unable to produce the vitamin itself, the human body has to obtain it via animal proteins. So far it has been known that on its way into the cell vitamin B12 is absorbed by little organelles, so-called lysosomes. From there, the vitamin enters the cell interior with the aid of the transport protein CblF, which was discovered by the same research team three years ago.

Researchers discover new genetic disease related to vitamin B12 deficiency

Vitamin B12 is essential to human health. However, some people have inherited conditions that leave them unable to process vitamin B12. As a result they are prone to serious health problems, including developmental delay, psychosis, stroke and dementia. An international research team recently discovered a new genetic disease related to vitamin B12 deficiency by identifying a gene that is vital to the transport of vitamin into the cells of the body.
