Brief Summary:
The purpose of this study is to detect whole chromosome abnormalities in maternal blood.

Condition or disease Intervention/treatment
Down Syndrome Edwards Syndrome Other: Maternal Blood Draw

Detailed Description:
The purpose of this study is to detect whole chromosome abnormalities on all chromosomes 13, 16, 18, 21, X and Y, in the fetus through analysis of cell free and compound sample DNA (cf DNA and cs DNA, respectively) in maternal blood. In addition, major deletions and duplications in chromosomes 1, 4, 5, and 22 will be detected.

Study Type : Observational
Estimated Enrollment : 340 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective Clinical Study to Evaluate a Novel Non-invasive Prenatal Screening Method for Characterizing Fetal Whole Chromosome Aberrations and Other Major Defects and Deletions Found in the Maternal Blood.
Study Start Date : March 2015
Estimated Primary Completion Date : November 2018
Estimated Study Completion Date : November 2018

Group/Cohort Intervention/treatment
Pregnant Women

Pregnant women who are scheduled to undergo an amniocentesis or chorionic villus sampling (CVS) procedure

Intervention: Single Maternal blood draw of 20mL

Other: Maternal Blood Draw
Maternal Blood Draw




Primary Outcome Measures :
  1. Validate the prenatal aneuploidy laboratory developed test (LDT) with maternal blood samples from pregnant women who are undergoing invasive prenatal diagnosis [ Time Frame: Participants will have a single visit and completion in study occurs once invasive procedure results have been recorded. ]

    A single 20 mL blood sample will be obtained from each subject during the first or second trimester, blind-coded, and transferred to the Sponsor Laboratory for processing to plasma.

    Subjects electing to undergo an invasive procedure for fetal Karyotyping (defined as standard cytogenetics and/or microarray, FISH, QF-PCR) will have the blood sample obtained prior to the procedure.

    The performance characteristics (sensitivity, specificity, negative and positive predictive value) of the laboratory developed test to detect whole chromosome abnormalities on all chromosomes 13, 16, 18, 21, X and Y will be determined using fetal karyotype on specimens obtained by chorionic villus sampling and/or genetic amniocentesis for those subjects who undergo these diagnostic procedures as part of their standard care as the gold standard.
