Edwards syndrome
trisomy 18

About 95% of the babies with Edwards syndrome die before they are born.

Sarah terminates her pregnancy because she finds out the baby will be born with Edwards syndrome.

Such cases are sometimes called mosaic Edwards syndrome.

The condition is now known as Edwards syndrome or trisomy 18 syndrome.

Edwards syndrome is caused by trisomy (three copies) of chromosome 18.

Triosomy 18 or Edwards syndrome, a genetic disorder caused by an extra 18th chromosome.

Edwards syndrome occurs in all human populations but is more prevalent in female offspring.

Down syndrome and Edwards syndrome are more common.

People with Edwards syndrome often have heart abnormalities, kidney malformations, and other internal organ disorders.

Edwards syndrome, which affects roughly one in 8,000 births, is a serious disorder that few afflicted babies survive.

Edwards syndrome occurs in around one in 6,000 live births and around 80 percent of those affected are female.

One percent of children born with this syndrome live to age ten, typically in cases of the less severe mosaic Edwards syndrome.

Edwards syndrome, or trisomy-18, the second-most-common trisomy.

Trisomy 18 (Edwards syndrome)

With a translocation, a person has a partial trisomy for chromosome 18, and the abnormalities are often less severe than for the typical Edwards syndrome.

Trisomy 13 was associated with Patau Syndrome and trisomy 18 with Edwards Syndrome.

Types of chromosome problems that are occasionally seen include Trisomy 18 (Edwards syndrome) or Trisomy 21 (Down syndrome).

Like all nondisjunction conditions (such as Down syndrome and Edwards syndrome), the risk of this syndrome in the offspring increases with maternal age at pregnancy, with about 31 years being the average.

The test, which was performed by Drs. Judith Chernevak and Camillo Gugliucci, showed that she was carrying a 16-week-old female fetus with Edwards syndrome, a rare birth defect.

Although women in their 20s and early 30s may conceive babies with Edwards syndrome, the risk of conceiving a child with Edwards syndrome increases with a woman's age.

An AFP test can also be done as part of a screening test to find other chromosomal problems, such as Down syndrome (trisomy 21) or Edwards syndrome (trisomy 18).

Edwards syndrome occurs in approximately 1 in 6,000 live births, but more conceptions are affected by the syndrome because the majority of those diagnosed with the condition prenatally will not survive the prenatal period.
