Sequencing of circulating cell free dna during pregnancy. Fetal chromosomal aneuploidy e g trisomy 21 monosomy x genomic sequence analysis panel circulating cell free fetal dna in maternal blood must include analysis of chromosomes 13 18 and 21. Maternal blood is sampled by venipuncture. Fetal dna sequencing improves the accuracy of prenatal screening tests for genetic conditions and at times has led to the diagnosis of maternal conditions that may have otherwise gone undetected.

Bianchi m d a senior researcher and institute director at the national institutes of health and her colleague. Analysis of cffdna is a method of non invasive prenatal diagnosis frequently ordered for pregnant women of advanced maternal age. Cell free fetal dna cffdna is fetal dna that circulates freely in the maternal blood. Rare autosomal trisomies revealed by maternal plasma dna sequencing suggest increased risk of feto placental disease.

Sequencing the fetal dna that circulates in a pregnant woman s blood holds promise for modern genomic medicine according to a review article by diana w. Sequencing of cell free dna during pregnancy biology because they show that fetuses with rare autosomal trisomies can survive well into the third trimester.

Bianchi moderator sequencing of cell free dna cf dna circulating in the plasma of pregnant women to screen for the common fetal autosomal aneuploidies is the first widespread. Rare autosomal trisomies are also associated with poor obstetrical outcomes in cluding in utero growth restriction and stillbirth. Assay of circulating cell free dna in pregnancy advances in dna sequencing have facilitated a change in the method used to screen for fetal chromosome trisomies.
