Aplasia (/əˈpleɪʒə/ ; 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]
Examples
- Acquired pure red cell aplasia
- Aplasia cutis congenita
- Aplastic anemia
- Germ cell aplasia, also known as Sertoli cell-only syndrome
- Radial aplasia
- Thymic aplasia, which is found in DiGeorge syndrome and also occurs naturally as part of the gradual loss of function of the immune system later in life
