Translocation Down syndrome: This type accounts for a small percentage of people with Down syndrome (about 3%). 2 This occurs when an extra part or a whole extra chromosome 21 is present, but it is attached or âtrans-locatedâ to a different chromosome rather than being a separate chromosome 21.
However, in one third of cases of Down syndrome resultuing from translocation there is a heriditary compontent-accounting for about 1% of all cases of Down syndrome. The age of the mother does not seem to be linked to the risk of translocation. Most cases are sporadic-chance-events.
