|Pregnancy-associated plasma protein (A PAPP-A)|
It is a protein produced by the placenta during the pregnancy. Levels of PAPP-A were studied during the first trimester and it was found to be low in pregnancies that subsequently delivered babies with Down syndrome and other chromosomal defects. PAPPA has been used in prenatal genetic screening and studies of atherosclerosis. Women with low levels of PAPPA in blood at 8 to 14 weeks of gestation have an increased risk of intrauterine growth restriction, trisomy 21, premature delivery, preeclampsia and stillbirth.
