Outcomes
Primary outcome [1] 0 0
The RNA study is an observational trial whose primary aim is to document the performance (sensitivity and specificity) of a laboratory developed test (LDT), using fetal nucleic acid in maternal plasma to identify Down syndrome in early pregnancy.
Timepoint [1] 0 0
Within 1st and 2nd trimesters
Secondary outcome [1] 0 0
The secondary aim is to develop a sample bank to allow documentation of subsequent improvements in the existing LDT or documenting performance of new methodologies.
Timepoint [1] 0 0
Late1st and early 2nd trimesters

Eligibility
Key inclusion criteria
- Pregnant women between about 10 weeks and 21 weeks 6 days gestation who are undergoing
a diagnostic procedure (i.e., chorionic villus sampling or amniocentesis) for
karyotype analysis who have, on average, a high prevalence of Down syndrome (about
1:30 to 1:50).

- Three main sources are pregnancies screen positive for:

1. the combined test at 10 to 13 weeks (NT, PAPP-A and hCG)

2. the second trimester quadruple test at 15 to 18 weeks gestation

3. integrated screening (PAPP-A and the quadruple test, with or without NT).

- Variations of the integrated test such as sequential testing will also be acceptable.

- Other, less common high risk groups would be women having diagnostic testing because
of maternal age of 38 years or older at delivery, pregnancies with an abnormal
ultrasound highly suggestive of a chromosome abnormality (e.g., major heart defect,
clenched fist), and women with an inherited form of Down syndrome (Robertsonian
translocation).

Summary
Brief summary
The study will examine the sensitivity and specificity of a circulating cell-free nucleic
acid test (DNA/RNA) to identify Down syndrome between about 10 weeks and 21 weeks 6 days
gestation. In addition, the new test may be used to identify trisomy 13 and 18 as part of a
more complete laboratory developed test. We hypothesize that the new circulating cell-free
fetal NA-based test will accurately and precisely measure specific fetal markers in maternal
circulation and that measurement will lead to the ability to noninvasively identify with high
sensitivity and specificity, fetal chromosome abnormalities, such as Down syndrome.
