Aplasia (/əˈplʒə/ (listen); from Greek a, "not", "no" + plasis, "formation") is a birth defect where an organ or tissue is wholly or largely absent. It is caused by a defect in a developmental process.[1][2]

Aplastic anemia is the failure of the body to produce blood cells. It may occur at any time, and has multiple causes.[1][2]
