Edwards Syndrome (Definition)

Edwards Syndrome happens with a frequency 1 in 6000 live births, and is the 2nd most common chromosomal syndrome, where there is an extra copy or part of an extra 18th chromosome. The classic physical findings include prominent occiput, clenched hands, and usually significant structural heart defects. The life span is short with usually severe mental retardation, ...Read more

Tested positive for trisomy 18 and i'm really scared. Is there any cure for this?

Sad news, sorry : Trisomy 18 is bad news by anyone's measure. The extra chromosome 18 is usually in every cell of the body. This distorts the formation of organs and body systems & provides severe limitations on function and lifespan. There is no cure. Some pregnancies end spontaneously, only 10% of newborns survive their first year. Rx is focused on maintaining comfort for their short lives. ...Read more

How are scientists looking into preventing Trisomy 18 from occurring?

How are scientists looking into preventing Trisomy 18 from occurring?

There is no way to : prevent genetic accidents that can occur as eggs & sperm split & half of the chromosomes from each join to form a new organism. Couples with increased risk of having a fetus with Down Syndrome because of known translocations or advanced maternal age can seek pre-pregnancy genetic counseling as well prenatal Chromosome Analysis or Chromosomal Microarray when calculated risk of DS is high. ...Read more

What're the causes of trisomy 18?

What're the causes of trisomy 18?

Error in formation: During the formation of the egg or sperm, the chromosome(c) pairs split with one of each going to the egg or sperm. At conception, the egg & sperm each bring 1 of each (c) & the embryo starts with a pair of each.If there is an error & the 18pair doesn't split but donates a pair of 18's to the egg, then it picks up a 3rd from the sperm. Age/toxins/radiation etc all may play a role in (c) errors. ...Read more

How do I know if I am a carrier of trisomy 18?

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. ...Read more

Trisomy (Definition)

Ordinary chromosomal traits require a pair of chromosomes to determine the traits. Occasionally, as a mistake in cellular division, there is a tripling of one of the chromosomes. When these occur, they usually cause unpleasant, and sometimes deadly conditions in the inheritor of these traits (e.g. Down's). Many we do not know about as they are ...Read more
