Pernicious anemia is more common among people from northern Europe, Scandinavia, and North America than among those from other parts of the world.

Large, immature red blood cells are found in the blood megaloblastsimpairing the ability of the blood to deliver oxygen to the tissues of the body. Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual. The mature blood cells, in addition to being fewer in number, may not function properly due to distortions in their shape.
