March 18 is Trisomy 18 Awareness Day. In recognition of this day, I have compiled a list of 18 things I think everyone should know about Trisomy 18.
1. Trisomy 18 is also known as Edwards Syndrome.
2. The incidence of trisomy 18 is approximately 1 in 3000 live births. This does not include babies who were miscarried early or born still.
3. There are three types of trisomy 18: full, mosaic, and partial. In full T18, every cell contains a third copy of chromosome 18. In mosaic T18, only some of the cells contain an extra 18th chromosome. In partial T18, only a part of an extra chromosome 18 is present instead of the entire chromosome.
4. Having a child with trisomy 18 occurs more often in older mothers but can also happen to younger mothers.
5. Trisomy 18 can be diagnosed in utero by chorionic villus sampling and amniocentesis, both of which are invasive tests and carry a small but real risk of miscarriage.
6. Newer blood tests such as MaterniT21, Panorama, and Harmony may also be used to detect Trisomy 18 as early as 9 weeks. A positive test result should be followed up with CVS or amniocentesis for diagnosis.
7. 90% of babies with trisomy 18 have a heart defect. More and more babies and children with T18 are undergoing heart surgery successfully.
8. Girls with T18 are more likely to survive than boys with T18.
9. Some babies and children with T18 can eat orally although most require a feeding tube. Some are fed both ways.
10. Every child with T18 is unique as T18 can affect the body in many different ways.
11. Babies and children with trisomy 18 have beautiful smiles!
12. The oldest living person with trisomy 18 currently (that I can find) is in her thirties!
13. Babies and children with T18 experience significant physical and cognitive disabilities but can learn new skills and interact with others.
14. Approximately 10% of babies born with T18 will reach their first birthday.
15. All babies and children with T18 are special.
16. Parenting a child with T18 is challenging in many ways, but it is also full of unique blessings.
17. Babies and children with T18 are adored by their siblings.
18. Life is a precious gift, including life with T18.
Our Julia was diagnosed with T18 on her second day of life. We are very blessed to have had 382 very special days together. We miss her every single day and are honored to be her family forever.
