Answer 1

If you are asking

what it is then it is the most common form of Down's syndrome, caused by an extra copy of chromosome number 21.

An extra chromosome inside the cells or some of the cells of people with Trisomy 21 results in the over-expression of certain genes, which, in turn, affects their brain and body's development.
