Today is the last day of October, which is Down syndrome awareness month. Take a moment to read this list of facts. Be educated. Be aware!
21 facts about Down syndrome
1. Down syndrome is a genetic condition. There are *three* types of Down syndrome: trisomy 21 (nondisjunction) accounts for 95% of cases (what my daughters have), translocation accounts for about 4% and mosaicism accounts for about 1%.
2. People with Trisomy 21 have 47 Chromosomes instead of 46 in each cell. This is because of an error in cell division called nondisjunction. At some point, a pair of 21st chromosomes in either the sperm or the egg fails to separate. As the embryo develops, an extra chromosome is copied in every cell of the body.
3. It occurs once in every 691 live births.
4. John Langdon Down, an English physician, named the anomaly “Down syndrome” in 1866.
5. More than 400,000 people in the U.S. have this genetic condition.
6. Individuals with Down syndrome, and their families, prefer “people first” language when referring to them. They are individuals who have Down syndrome. Babies with Down syndrome are not down’s babies.
7. Most people with Down syndrome fall into the mild to moderate range of mental impairment.
8. Several health complications could occur in individuals with Down syndrome. Some include heart defects, low muscle tone, thyroid disease, and vision and hearing problems. However, most of these conditions, when treated, do not get in the way of people living full lives.
9. Down syndrome affects people of all ages, races and economic levels.
10. People who have Down syndrome are active participants educationally, vocationally, socially and recreationally.
11. Polly and Evie and other individuals with Down syndrome are not always happy, although that is a generalization that people make. They both absolutely can be happy. They also get mad, grumpy, tired, selfish, and frustrated, just like the rest of us.
12. Individuals with Down syndrome are more like you, than different.
13. Most little ones, from birth to age three, take advantage of early intervention therapies, like physical therapy, occupational therapy, speech therapy and developmental therapy.
14. Years ago, people with Down syndrome were usually institutionalized with the assumption that they were unable to learn. That assumption has been proved inaccurate.
15. Quite a few people with Down syndrome are ultra-flexible.
16. Down syndrome is not a death sentence for the individual, nor for the family.
17. All the chromosomal material in individuals of people who have Down syndrome is normal. There is just more of it.
18. Many children with Down syndrome are in included now in typical classrooms throughout the U.S.
19. People with Down syndrome are not all the same. They are individuals with individual strengths, weaknesses, desires and struggles.
20. The diagnosis at first is based on physical characteristics that are usually seen in babies with Down syndrome. Things like: low muscle tone, a single crease across the palm of the hand, a slightly flattened facial profile and an upward slant to the eyes. Then a blood sample is taken to confirm or disprove the suspicion.
21. 80% of babies with Down syndrome are born to mothers under the age of 35.

Ive never seen the 22% stat under 35, much lower than I’d guess with all the statements about how more common under 35. Which apparently isn’t the case!!
Was that last stat changed? It’s reversed now. !!!??! But it fits what is repeated over & over (most births are under 35). This split between under & over 35 is what may skew widely with reasonably affordable, non-invasive prenatal testing.
Just one thing I would add to this *wonderful* list: There are *three* types of Down syndrome: trisomy 21 (nondisjunction) accounts for 95% of cases (the type you mention), translocation accounts for about 4% and mosaicism accounts for about 1%. (in other words, what the other 5% are 🙂
GREAT POINT! Thanks Carolyn :).
I changed number one to account for all three types of Down syndrome. Thanks so much for your help :)!!!
Cool! Now people won’t wonder what happened to the other 5% 🙂
:), I get by with a little help from my friends!
