Down syndrome is a genetic disorder caused by the presence of an extra chromosome (or part thereof) on chromosome pair 21, so that the cells of the people have three chromosomes in the pair, however, there are only two in normal condition.

However, it was in July 1958, when the French geneticist JÃÂ©rÃÂ´me Lejeune discovered that the syndrome is a chromosomal abnormality of chromosome 21.
Down syndrome is the leading cause of intellectual disability and the most common human genetic disorder.
The incidence increases with maternal age, especially when it exceeds 35 years, being the only risk factor shown to have a child with Down syndrome. Down syndrome is a disease and therefore requires no medical treatment as such. Furthermore, it is impossible to know the causes of the problem, hence, it is very difficult to avoid it.
The health of children with Down syndrome does not have anything different with other child, so, in many cases if their health is good or bad, it has nothing to do with trisomy. Therefore, we can have healthy children with Down syndrome, not having any physical disability or issues.
They are health complications related to their genetic alteration: congenital heart disease, pulmonary hypertension, hearing or vision problems, bowel abnormalities, neurological, endocrine. These situations require specific care and appropriate monitoring especially at birth. Fortunately most of them are treatable, either through medication or by...
