Acquired aplastic anemia is a rare disorder caused by profound, almost complete bone marrow failure. It is believed that a significant number of cases go undiagnosed. However, since the disorder also tends to occur with greater frequency in certain families than in others, it is also believed that there may be a genetic component to pernicious anemia.

Pairs of human chromosomes are numbered from 1 through 22 and the sex chromosomes are designated X and Y.
