Down syndrome is a genetic chromosome 21 disorder causing developmental and intellectual delays. It is a genetic disorder caused when abnormal cell division results in extra genetic material from chromosome 21.
Down’s syndrome causes a distinct facial appearance, intellectual disability and developmental delays. It may be associated with thyroid or heart disease.

Adequate access to health care, to early intervention programmes, and to inclusive education, as well as appropriate research, are vital to the growth and development of the individual.
