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.
Medical experts believe the cell changes most often start in a woman's egg before or at conception. Less often, the error occurs in sperm at conception. It is not known what causes the cells to divide abnormally. One type of Down syndrome, called translocation-type, may be passed down through families (inherited).
