Brief Summary:
This study evaluates the utility of expanded panel non-invasive prenatal testing (NIPT) in detecting confined placental mosaicism of rare autosomal trisomies among pregnancies with placentally-mediated complications, including fetal growth restriction and severe preeclampsia.

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   Female
Sampling Method:   Non-Probability Sample
Study Population
This study includes separate cohorts of pregnant women with placentally-mediated complications (fetal growth restriction, severe preeclampsia, and low PAPP-A levels), as well as a cohort of healthy pregnant women with no pregnancy complications.
Criteria

Inclusion Criteria:

  • For fetal growth restriction cohort: diagnosis of early onset (< 34 weeks) severe fetal growth restriction, defined as estimated fetal weight less than 10th percentile with abnormal umbilical artery Dopplers OR estimated fetal weight less than 5th percentile alone OR biometric size at least 14 days behind expected dates
  • For severe preeclampsia cohort: diagnosis of early onset (< 34 weeks) preeclampsia with severe features, diagnosed by ACOG criteria
  • For low PAPP-A cohort, diagnosis of low PAPP-A levels (pregnancy associated plasma protein A), defined as less than 0.2 multiples of the median
  • For healthy cohort, normal pregnancy with no evidence of maternal, obstetrical, or fetal complications

Exclusion Criteria:

  • Maternal age < 18 years
  • Multifetal gestation
  • Chronic hypertension
  • Tobacco or drug use
