Hereditary vitamin B12 deficiency anaemia – http://id.who.int/icd/entity/1463520192
This is a hereditary low blood level of vitamin B12. It can cause permanent damage to nervous tissue if left untreated long enough. Vitamin B12 itself was discovered through investigation of pernicious anaemia, which is an autoimmune disease that destroys parietal cells in the stomach that secrete intrinsic factor.
