What causes Down syndrome?

All in all, the descendants, the parents, give their children to deal with Genesis. These genes carry on chromosomes. When the baby should develop to size, each person has the thought of bringing the cell 23 chromosomes in 46 pairs from the chromosome to the total. And half of the chromosomes from the mother and the other half from the father.

The syndrome was one of the chromosomes that did not separate properly. The baby at the end with three concerns outside is an example. A man is outside of the brain, and the physical characteristics of these things cause problems.

The substances in the blood that are the hallmarks of Down syndrome and a specific ultrasound marker are measured. Blood markers are plasma protein A and human chorionic gonadotropin (free beta-hCG) associated with pregnancy. The ultrasound marker is the thickness of the core transparency (NT).

In Down syndrome pregnancies, PAPP-A tends to be low and NT plus hCG tend to increase. The values of these indicators are used. It moves along with your age to estimate the likelihood that a pregnancy will be affected by Down syndrome.
