How long can you live with Trisomy 18?
It is difficult to predict the life expectancy of a baby with trisomy 18 if the baby does not have any immediate life-threatening problems.
For babies that have survived their first 30 days of life, 36% were alive at one year.
About 10% of children born with trisomy 18 survive until 10 years of age..
Can trisomy 18 happen twice?
What is the recurrence risk for trisomy 18? The recurrence risk for trisomy 18 depends on the type of trisomy 18 in an affected family member (full, mosaic, or partial trisomy 18). The recurrence risk for a family with a child with full trisomy 18 is usually stated as 1% (1 in 100).
Why do trisomy babies die?
The cells of these babies have three copies of chromosome 18 instead of the usual two. There is no cure. Most babies with trisomy 18 die before they are born. The majority of those who make it to term die within five to 15 days, usually due to severe heart and lung defects.
Can a person with Edwards syndrome have a baby?

Babies with trisomy 18 are often born very small and frail. They typically have many serious health problems and physical defects, including: Cleft palate. Clenched fists with overlapping fingers that are hard to straighten.
Does trisomy 18 run in families?
Most cases of trisomy 18 are not inherited, but occur as random events during the formation of eggs and sperm. An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes. For example, an egg or sperm cell may gain an extra copy of chromosome 18.
Does trisomy 18 come from Mom or Dad?
For example, the chance of having a baby with Trisomy 18 is higher in older mothers. In other cases, Trisomy 18 can be inherited due to a familial chromosome rearrangement called a translocation. Trisomy 18 is never the result of anything a mother or father did, or didn’t do.

Trisomy 18 affects females more frequently than males by a ratio of three or four to one. Large population surveys indicate that it occurs in about one in 5,000 to 7,000 live births.
Can ultrasound show Trisomy 18?
The only definitive methods to make a diagnosis of trisomy 18 are through ultrasound imaging, particularly during the first and second trimesters, triple tests and invasive testing with amniocentesis or chorionic villous sampling (1, 5, 6).
Can trisomy 18 babies open their hands?
Identification of one normal open hand probably would be sufficient to identify fetuses with trisomy 18. In our experience, when fist- ing or overlapping digits are present, both hands have been affected. Nyberg and colleagues’ study of fetuses with trisomy 18 also suggests this.
How old is the oldest person with Trisomy 13?
19-year-oldNo mosaicism was detected in repeated cytogenetic studies. The 19-year-old patient is the oldest known living person with regular trisomy 13.
