Question: trisomy 21 what is that is it risk?
Trisomy 21: A common chromosome disorder, often called Down syndrome, due to an extra chromosome number 21 (trisomy 21). The chromosome abnormality affects both the physical and intellectual development of the individual.
Trisomy 21 (Down) syndrome is associated with a major risk for heart malformations, a lesser risk of duodenal atresia (part of the small intestines is not developed), and a minor but still significant risk of acute leukemia.
Trisomy 21 is due to an extra copy of chromosome number 21. Instead of having the normal 2 copies of chromosome number 21, the person with Down syndrome has 3 copies of chromosome number 21.
You can talk to a doctor more about it, they can help you to understand better.
