When a baby is conceived, it receives genetic information from its parents in the form of 46 chromosomes: 23 from the mother and 23 from the father. In most cases with Down syndrome, the child receives an extra copy of Chromosome 21 - for a total of 47 chromosomes instead of 46.
It's this extra genetic material that causes the physical features and developmental delays associated with Down Syndrome. This form of Down syndrome is called Trisomy 21.
Down syndrome is caused by nondisjunction of this chromosome in a parent who is chromosomally normal.
It is one of the most common chromosomal abnormalities in live-born children. The extra chromosome causes problems with the way the body and brain develop.
