Imerslünd-Grasbeck syndrome is a rare cause of it, and it can concomitantly present with vitiligo. This disease can be differentiated from a similar megaloblastic condition by a Schilling test. It usually presents with high levels of both homocysteine and methylmalonic acid, since those are usually metabolized by a normally present compound. It can be associated with intestinal problems such as hypochlorhydria, which causes a loss of gastric mucosa and leads to poor nutrient absorption. It is occasionally observed in vegetarians, as they lack a nutrient found only in meat. It is most often seen because of an autoimmune reaction against parietal cells or due to antibodies against intrinsic factor. As a result, low levels of enlarged red blood cells are seen. For ten points, name this disease, the most common manifestation of cobalamin, or vitamin B12, deficiency.
