Most babies with trisomy 18 or trisomy 13 die within the first year of life.Ī cfDNA screening has very little risk to you and your baby, but it can't tell you for sure whether your baby has a chromosome disorder.

These disorders are rare but more serious than Down syndrome. Other trisomy disorders include Edwards syndrome (trisomy 18), where there is an extra copy of chromosome 18, and Patau syndrome (trisomy 13), where there is an extra copy of chromosome 13.Down syndrome is the most common chromosome disorder in the United States. In Down syndrome, there is an extra copy of chromosome 21.A trisomy causes changes in the way the body and brain develop. If one of these pairs has an extra copy of a chromosome, it's called a trisomy.People normally have 46 chromosomes, divided into 23 pairs, in each cell.They carry information that determines your unique traits, such as height and eye color. Genes are parts of DNA passed down from your mother and father. Chromosomes are the parts of your cells that contain your genes. A cfDNA screening checks this DNA to find out if the baby is more likely to have Down syndrome or another disorder caused by a trisomy.Ī trisomy is a disorder of the chromosomes. During pregnancy, some of an unborn baby's DNA circulates in the mother's bloodstream. Prenatal cell-free DNA (cfDNA) screening is a blood test for pregnant women.
