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.
The third form, translocation Down syndrome, occurs when the extra chromosome in the 21 pair breaks off and attaches itself to another chromosome. Translocation Down syndrome is the only form that may be inherited. A parent who possesses a balanced translocationâa chromosome rearrangement with no extra genetic material from chromosome 21âcan pass the translocation to an offspring. Carriers of balanced translocations do not have signs or symptoms of the disorder.
