About nine out of 10 babies with Down syndrome will survive their first year, and nearly half of these will reach 60 years of age. It is not possible to assess the degree of handicap before the baby is born. Down syndrome is always associated with moderate to severe developmental disability and is often associated with physical problems such as heart defects and difficulties with sight and hearing. Although Down syndrome occurs more frequently as mothers get older, about 70 percent of babies with Down syndrome are born to women who are younger than 35 years old. Usually, it is not inherited, so a baby can be affected even if there is no history of Down syndrome in the family. In an unscreened population, about one in every 700 babies is born with Down syndrome. It does not store any personal data.Down syndrome is caused by the presence of an extra chromosome number 21 in the cells of the developing baby.

For example, it is used to assess the risk for a neural tube defect. AmniocentesisĪmniocentesis is a procedure in which a small amount of amniotic fluid (the fluid surrounding the fetus) is removed and analyzed to test the chromosomes of the fetus. CVS is performed between 10.5 and 12.5 weeks of pregnancy. In CVS testing, a small amount of tissue from the placenta is removed to analyze the chromosomes of the fetus. Specific maternal conditions such as diabetes or lupus.A family history of congenital heart disease.Fetal echocardiographyįetal echocardiography is an ultrasound exam that looks for abnormalities in the heart of the fetus. The sonogram also helps determine organ development in the fetus. The genetic sonogram is an ultrasound exam that looks for physical signs that may indicate chromosome abnormalities in the fetus. The American College of Obstetrics and Gynecology now recommends first trimester screening for all pregnant women.

Open neural tube defects (failure of the bones and tissue over the spine to close).Extra chromosomal material (Trisomy 18).The screening determines risk to the fetus for: This screening combines an ultrasound performed between 10.5 and 14 weeks of pregnancy with a first or a first and second trimester blood test.
