Down syndrome is a genetic disorder that causes intellectual and developmental delays. The cases of Down syndrome are as rare as 1 million per year. Though, it cannot be cured, treatment is of some help. The genetic condition arises after an abnormal cell division leads to extra genetic material resulting from chromosome 21. The symptoms are visible in the form of an intellectual disability, a different facial appearance, developmental delays and are sometimes caused due to heart or thyroid ailments.
