Most fetuses with trisomy are miscarried during the first trimester. Most of those who survive have Down syndrome, also known as trisomy 21 because it's caused by an extra chromosome 21. While all babies with Down syndrome have some degree of mental impairment, it's severe in only about 10 percent.
