Those that do can have serious complications including:
- Breathing difficulties.
- Congenital heart defects.
- Hearing loss.

What organs are affected by Trisomy 18?
Affected individuals may have heart defects and abnormalities of other organs that develop before birth. Other features of trisomy 18 include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers .
Do babies with trisomy 13 suffer?
Patau’s syndrome (trisomy 13) is a rare condition, associated with high mortality, a range of congenital abnormalities, and severe physical and cognitive impairment. Many affected pregnancies will miscarry, and most babies born with the condition will not survive more than a few days or weeks.
Does trisomy 13 affect males or females?
Trisomy 13, known as Patau Syndrome, is a rare condition resulting from genetic errors on the 13th chromosome. The disorder occurs in approximately 1 in 16,000 live births and much more commonly affects females than males. This disorder causes severe intellectual and physical problems.
Which trisomy is fatal?
The term trisomy describes the presence of three chromosomes instead of the usual pair of chromosomes. For example, trisomy 21, or Down syndrome, occurs when a baby has three #21 chromosomes. Other examples are trisomy 18 and trisomy 13, fatal genetic birth disorders.

How old is the oldest person with trisomy 13?
The mean survival of the 19 patients who died was 97.05 days; translocation patients survived longer than regular trisomy patients. The oldest living patients with trisomy 13 are a girl 19 and a boy 11 years old.
Who is most likely to get Patau syndrome?
Trisomy 13 Syndrome is sometimes called Patau Syndrome, after one of the researchers (Patau K) who identified the syndrome’s trisomic origin in 1960. The syndrome appears to affect females slightly more frequently than males and occurs in about one in 5,000 to 12,000 live births.
Do babies with Trisomy 18 suffer?
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.
What body systems are affected by Edwards syndrome?
Many parts of the body are affected. Babies are often born small and have heart defects. Other features include a small head, small jaw, clenched fists with overlapping fingers, and severe intellectual disability.
|Other names||Trisomy 18 (T18), chromosome 18 duplication, trisomy E syndrome|
How common is trisomy 13 in pregnancy?
Trisomy 13 happens in about one in 7,400 pregnancies in the United States. The risk for trisomy 13 goes up as a mother gets older, but any woman at any age can have a baby with trisomy 13.
What is a T18 baby?
Trisomy 18 is the second most common type of trisomy syndrome, after trisomy 21 (Down syndrome). About 1 in every 5,000 babies is born with trisomy 18, and most are female. The condition is even more common than that, but many babies with trisomy 18 don’t survive past the second or third trimester of pregnancy.
