Mosaic Down syndrome is when some of the cells in the body do not have trisomy 21 and some cells have trisomy 21, an arrangement called a mosaic (46,XX/47,XX,+21). [6] [7] This can occur in one of two ways: A nondisjunction event during an early cell division leads to a fraction of the cells with trisomy 21;

The most common abnormality the test can screen is trisomy 21 (Down syndrome).In addition to Down syndrome, the triple and quadruple screens assess risk for fetal trisomy 18 also known as Edwards syndrome, open neural tube defects, and may also detect an increased risk of Turner syndrome, triploidy, trisomy 16 mosaicism, fetal death, Smith–Lemli–Opitz syndrome, and steroid sulfatase ...
