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.
People with translocation Down syndrome can inherit the condition from an unaffected parent. The parent carries a rearrangement of genetic material between chromosome 21 and another chromosome. This rearrangement is called a balanced translocation.n these people, the condition is called mosaic Down syndrome. Researchers believe that having extra copies of genes on chromosome 21 disrupts the course of normal development, causing the characteristic features of Down syndrome and the increased risk of health problems associated with this condition.
