Translocation occurs when part of the twenty-first chromosome breaks attain and attaches to another cell. The consider number of chromosomes is 46, however the excess material from the twenty-first chromosome results in the affects of the syndrome. With translocation, most cases occur sporadically, with no position on maternal age. These two types of this syndrome atomic number 18 very rare, being responsible for completely 6 or 7 percent of all cases.         Children with Down syndrome are at high luck for health problems.

These admit innate(p) heart defects, respiratory problems, increase suseptibility to infections, and/or block digestive tracts.
