Hereditary Persistence of Alpha-Fetoprotein Is Associated with the -119G>A Polymorphism in Gene.

Alpha-fetoprotein (AFP) is a glycoprotein that is produced by the liver and yolk sac during fetal development. Its levels are usually raised in malignant conditions. Hereditary persistence of AFP (HPAFP) is a rare benign condition with elevated levels of AFP. It is inherited in a dominant mode with complete penetrance and is usually not associated with any clinical disability. We report two individuals with elevated levels of AFP harboring the -119G>A polymorphism in the gene. A genetic screening to rule out variants in the gene is advised in cases with unexplained persistent AFP levels to avoid inappropriate treatment and surgical options.
