Down syndrome is due to a chromosomal abnormality of the numerical type. There is an additional chromosome 21 to the karyotype. Therefore they have 47 chromosomes (47XX+21 for girls and 47XY+21 for boys). This larger number of chromosomes is the reason for different changes in the normal development of the body and the brain. This syndrome is the most common reason of birth defects with people. Usually there is one incident in 2000 conceptions. This rate is with women under the age of 25. The older the women are, the higher the chance of Down syndrome is.

In 4% of the cases except a trisomy 21 there is also another chromosomal abnormality. It occurs a translocation between chromosome 21 and chromosome 13, 14 or 15. This causes additional changes in the normal development.
