Pappalysin-1 - Wikipedia Pappalysin-1, also known as pregnancy-associated plasma protein A, and insulin-like growth factor binding protein-4 protease is a protein encoded by the PAPPA gene in humans [1] PAPPA is a secreted protease whose main substrate is insulin-like growth factor binding proteins Pappalysin-1 is also used in screening tests for Down syndrome [2][3]
PAPP-A Test: Everything You Need to Know - pregnancyarchive. com By detecting low levels of PAPP-A, the test can help identify pregnant women who are at a higher risk of developing preeclampsia, allowing for early intervention and appropriate management to reduce the chances of a serious complication, such as a stroke

Pregnancy-Associated Plasma Protein (PAPP)-A2 in Physiology and Disease Some of the most recent advances in understanding the implications of this axis in human growth are derived from the identifications of new mutations in the gene encoding the pregnancy-associated plasma protein PAPP-A2 protease that liberates IGFs from their carrier proteins in a selective manner to allow binding to the IGF receptor 1
Pregnancy-associated plasma protein-A - Radiopaedia. org Pregnancy-associated plasma protein-A (PAPP-A) is a protein found in the maternal circulation and is produced by the placenta The PAPP-A gene has been assigned to human chromosome 9q33 1 and contains 22 exons 5 PAPP-A values tend to rise exponentially during pregnancy and the reference range depends on the stage of gestation
Variation of Papp-A Level in the First Trimester of Pregnancy and Its . . . In particular, low maternal serum pregnancy-associated plasma protein-A (PAPP-A), at 11–13 weeks of gestation, is associated with stillbirth, infant death, intrauterine growth restriction, preterm birth, and pre-eclampsia in chromosomally normal fetuses, while a raised nuchal translucency is associated with specific structural abnormalities and
Low PAPP‐A: what are the clinical implications? - PMC Recent evidence has shown that low levels of Pregnancy‐associated plasma protein A (PAPP‐A) at the first trimester screening test can be an independent risk factor for certain adverse pregnancy outcomes such as intrauterine fetal death after 24 weeks, spontaneous fetal loss before 24 weeks, preterm birth, gestational hypertension, preeclampsia a
