Best Answer
Copy

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.
Down syndrome or trisomy 21 is caused by nondisjunction of chromosome 21 in a parent who is chromosomally normal and is one of the most common chromosomal abnormalities in liveborn children.

Down's syndrome is caused when there is an extra chromatin present in chromosome 21 when an child is born.

Can gene therapy be used as treatment for Down syndrome?

No. Gene therapy alters a person's genetic code, generally by inserting a genetic sequence. Trisomy 21 (downs syndrome) is caused by the presence of a copy (or part of a copy) of the 21st chromosome. Genetic therapy would not be able to remove this extra chromosome. It might be possible (in the future) to "turn off" the extra chromosome, and stop trisomy-21 at the embryo stage. However, by the time a person is born, the physical damage from downs syndrome has been done. After a few months to a year or so, the mental damage from downs syndrome will also be done. So no "treatment" for downs syndrome will be possible using genetic modification such as gene therapy.
