Mosaicism (where some cells of the body are different from others-there are at least two cell types) occurs when the extra chromosome is not passed on to all the cells created from the original cell; hence, the baby has some cells that have a trisomy with 47 chromosomes and some cells that are normal with 46 chromosomes. This content comes from a hidden element on this page. Method A total of 35 consecutive cases underwent screening for trisomies by cell-free DNA testing between April 2015 and November 2017 due to suspicious NIPT results; these cases represented 0.11% of patients (35/31,250) with similar frequencies of .

During chorionic villus sampling, a tissue sample is removed from a portion of the placenta. Chromosomes are found in the nucleus of all body cells except red blood cells. Each chromosome has unique regions or bands that contain genes, and each band is labeled numerically. Translocations occur when regions of certain chromosomes break off and are rearranged, resulting in shifting of genetic material and an altered set of chromosomes. Full trisomy 16 is incompatible with life. Impossible to tell the life expectancy without knowing what the extent of the genetic translocation of the extra gene is.
