Part Description

LP19800-9   Chromosome 21 trisomy
Trisomy 21 risk refers to the fetus's risk of having trisomy 21. The risk can be estimated based on maternal age, prenatal genetic testing of fetal DNA, various maternal lab tests, and fetal nuchal translucency or nuchal fold measurements. Trisomy 21, also called Down syndrome, is caused by the presence of three copies of either the entire chromosome 21 or a crucial region of chromosome 21 in each cell rather than two. Down syndrome is associated with cognitive delay, various forms of congenital heart disease, hearing loss, and leukemia, and characteristic physical features. The risk for Down syndrome increases with increasing maternal age. The general population risk of Down syndrome is 1 out of 650 to 1,000 live births; for a 30-year-old woman, the risk is 1 out of 1,000, while for a 40-year-old woman it nears 1 out of 100.
