n.
Any of several antigens normally present in a fetus and occurring abnormally in adults as a result of certain cancers or diseases of the liver.

fetoprotein

[-prō′tēn]
Etymology: L, fetus + Gk, proteios, first rank
an antigen that occurs naturally in fetuses and occasionally in adults as the result of certain diseases. An increased amount of alpha-fetoprotein in the fetus is diagnostic for neural tube defects. The presence of beta-fetoprotein in the blood of adults is associated with leukemia, hepatoma, sarcoma, and other neoplasms.

fe·to·pro·tein

, alpha (α)-fetoprotein (AFP) , gamma (γ)-fetoprotein , beta (β)-fetoprotein (fē'tō-prō'tēn, al'fă, gam'ă, bātă)
Fetal proteins found in small amounts in adults in the following forms: 1) AFP increases in maternal blood during pregnancy; when detected by amniocentesis, is an important indicator of neural tube defects (e.g., spina bifida); used as a tumor marker in adults with hepatocellular carcinoma; 2) beta (β)-fetoprotein, although a fetal liver protein, has been detected in adult patients with liver disease; and 3) gamma (γ)-fetoprotein occurs in association with various neoplasms.
