It's a chromosal disorder. Caused by the presence of an extra 21st chromosome?
Called trisomy 21. A zygote is only meant to have 2 pairs of chromosome 21 (one from mum one from dad) but if cell division is faulty, then the chromsomes may not segregate properly when gametes are being formed. The chances of having a down's child dramatically increases as the parents become older as this cell division tend to not be so exact as when younger.
