  • Interesting facts about down syndrome:


Down syndrome is the only kind of inherited trisomy that you can still live after getting it. The have been only two other kinds of trisomys' that a child can be born with and still survive. These are trisomys 13 and 18, and although you can be born and live with these the odds of living past age 1 is 5%.
In around 90% of cases of down syndrome the extra chromosome 21 comes from the mothers egg and not the fathers sperm.
Down syndrome although only around 5,500 babies are born with it each year in the United States as of 2011, is the most common kind of chromosomal disorder in birth which is why it is such a big problem.
