Methodology

This non-invasive prenatal test (NIPT) is performed on maternal blood to screen for specific chromosomal aneuploidies in fetus. Cell-free DNA isolated from maternal blood, which contains maternal and placental DNA, is amplified at >13,300 specific loci using a targeted PCR assay and sequenced on Illumina NextSeq instrument. Sequence data is analyzed using Natera’s Constellation software to estimate fetal fraction, and to determine the fetal copy number for chromosomes 13, 18, 21, X and Y, thereby identifying the risk of whole chromosome abnormalities at these locations. Genetic interpretation services are performed by Natera CLIA lab (CLIA# 05D1082992). Conditions screened include trisomy 13 (Patau syndrome), trisomy 18 (Edwards syndrome), trisomy 21 (Down syndrome), and monosomy X (Turner syndrome).
