Q: what does it mean if i tested positive for trisomy 18? should i be worried?

Confusing question: Are you saying you have T18, or your pregnancy is positive for T18. The first response would not be possible. The second is worrisome. Those with any trisomy have birth defects, many of which are life threatening.Few with T18 live past a year of age.

Question 1

what is edwards syndrome (trisomy 18) like?

Accepted Answer

Extra chromosome: In trisomy 18 the patient has an extra chromosome 18.  This genetic disorder frequently causes heart and kidney defects. They may have a small head and jaw and usually have severe developmental delay. Here is a link http://www.Trisomy18.Org/site/pageserver?Pagename=whatist18_whatis.

Question 2

how do you treat edwards syndrome (trisomy 18)?

Accepted Answer

Keep them comfortabl: These patients are supported with  comfort measures as much as possible. Fluids, nutrition, oxygen, etc.As a universally fatal disorder, management focuses on comfort rather than things that would prolong the act of dying.

Question 4

where can i find more information on trisomy 18 or edwards syndrome?

Accepted Answer

Trisomy18.org: There is a foundation set up for this syndrome - go to http://www.Trisomy18.Org.

Question 5

is it possible for someone with edwards syndrome (trisomy 18) have children in the future if they live long enough?

Accepted Answer

Maybe: This is complicated. First, in most cases, there is an extra chromosome in all cells so the sperm and eggs will be genetically defective anyways & so can't create an embryo. Rarely, one can have mosaicism in which some cells have trisomy 18 - theoretically, the sex cells could have the normal 23 pairs. However, there's also anatomic problems like undescended testes in males. So the odds are low.

Question 6

trismoy21  1: 1067 trisomy 18 1: 2674 trisomy 13  1: 8368  does it mean my child has down sydrome?

Accepted Answer

Unclear: The information you list provides no specific information on which to base an answer. How was the data obtained and why? Does it relate to some specific test, a pregnancy, a genetic counseling session ? Questions should provide basic information on the problem and ask a clear question. The public site is not a chat room and none of your prior submissions are linked. Try again if you wish.

Question 7

what're the causes of trisomy 18?

Accepted Answer

Genetic accident.: Trisomy 18 is a generally perinatally lethal (few exceptions prove the rule) genetic aberration that occurs when chromosomal non-disjunction occurs in either the maternal or paternal gamete (egg, sperm). There is no cure and comfort care is all that is ethically permissible.

Question 8

how do i know if i am a carrier of trisomy 18?

Accepted Answer

Chromosome study: Most trisomy 18's arise as a new error on meiosis during the formation of a womans egg.It is not "carried" like a sickle trait. There is a rare possibility that infants with trisomy 18 picked up the material from a parent with a balanced switch between 2 chromosomes.The babies study would show the translocation not t18, parents would need to be studied in such a case.

Question 9

when do people get tested as a carrier for trisomy 18?

Accepted Answer

Translocation: If the edwards syndrome infant has translocation (joining of chromosomes) rather than a free-standing extra 18 chromosome (trisomy), then the parent may "carry" this translocation in balanced form without symptoms. Translocation carriers can have a 10-50% risk for future infants with edwards as opposed to the very small risk (<1%) when the child has trisomy 18.

Question 10

what does it mean if i tested positive for trisomy 18? should i be worried?

Accepted Answer

Confusing question: Are you saying you have T18, or your pregnancy is positive for T18. The first response would not be possible. The second is worrisome. Those with any trisomy have birth defects, many of which are life threatening.Few with T18 live past a year of age.
