How long do Trisomy 8 people live?

Try looking on webmd.com or another medical site. I think they can live into their 50s but most don't get very old.

If the child is HIV positive, he or she won't last long into his or her teens. If they already have AIDS, then probably not past five or six. These are estimates, the actual lifespan may differ by a number of years.

I think your describing "Edward's Syndrome" or trisomy 18 where most infants die at birth and only 5-10% survive the first year of life. According to a web site- one has made it to the teenage years, but very rarely. \n\nhttp://www.medscape.com/medline/abstract/12671111?queryText=trisomy%2018\n\nthese trisomies include, renal cardiac, brain and \nfacies abnormalities\n\nhttp://en.wikipedia.org/wiki/Edward's_syndrome\n\nit could also be trisomy 13 but i think these children  have a slightly better prognosis

I taught school for 25 years.  The oldest person I even knew was a young boy of 12 with CF, who gasped for every breath, was angry at his parents for having him (CF is an inherited disease -- when both parents carry the recessive gene, each pregnancy is a 1 in 4 chance of getting the disease.  These parents had 4 children, 3 of the 4 had the disease).  Kevin was his name.  He skin was blue most of the time, and he'd be gone every other week or so to the City of Hope to have the mucous pounded out of his chest.  He was old. He was 12)  When I was a little girl, the most energetic person I knew was 84.  She gardened, she and her husband travelled all over the world, she was spry and foxy and cute, and smiled, and told funny stories.  She was young.  One's years have nothing to do with age.  You are old when you can no longer take care of yourself, when you are sick/confused/depressed/etc.  It is not your exterior shell that one should regard as old, but your spirit, and energy.  Helpful???  bit of a different answer that you have in the answers above this one....

My grandmother dropped dead peeling potatos at 63 years old from an anuerysm in her heart. My mother and her only sister had brain anuerysms at the age of 45.(They were both 45 years old.) My aunt died within 24 hours. My mother lived because hers started to actually seal itself closed. She had brain surgery and was in an induced coma for a month after surgery. \nYou can email me by clicking on my profile and going to my profile page. I won't give out my email address here because I was turned in for "chatting and personal whatever" it is that you receive a violation for........I will be glad to answer any questions you might have...................

Your mother donates 23 chromosomes and your father donates 23 giving you 46 chromosomes total. Mutations, such as Trisomy-21, do occur where people can have less or more which usually results in some form of genetic disease.

well, they'll live for 40 days, but it impossible to tell how long their body will funcion, because everyone is different.

Yes, my mother had it since she was in her twenties. She had six children, two coming after she was diagnosed. We are all grown and my mother is now 80. She is actually doing much better now than she was during the early times.\n\nI doubt if there's any serious side effects to be had in your unborn child. I do wish you well and much luck with your condition. I don't wish this on anyone. God bless.

Because of advances in Medicine. That is the whole reason why people live longer and more babies live past being an infant. If it were not for medicine, the human race would still have an average life span on 25-35 years.

It is trisomy 21 and it is non-disjunction, and it occurs during the first meiotic division. In fact 50-60% of all conceptions terminate in spontaneous abortion, and 50% of those have major chromosomal defects. Trisomy 21 will  yield a live birth. The problem is that the egg is arrested in the diplotene stage of meiosis, sort of like being on pause. So asking the chromosomes to split perfectly after being on pause for say 35 years, well then the genetic problems really escalate.

I've checked it out and cant find that specific answer, but i've found that out of 10 people diagnosed with cancer, only ONE will survive for a max of 5 years.\n\nIts the most Lethal worldwide, claiming over 3 million people a year.\n\nRead more about it in the source link ---->

The following quote is from \n\nhttp://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=3607844&query_hl=6&itool=pubmed_docsum\n\n"prophase lasted 4.8 hr; metaphase, 0.2 hr; anaphase, 0.06 hr and telophase, 3.3 hr, while the interphase lasted 5.4 hr. In accordance with this, the duration of the whole mitotic process was 8.4 hr."

Yes, but there is an increased risk of their child also having Down Syndrome. Sometimes very mentally retarded people are sterile though, so if this is a question pertaining to a certian someone you know, they'd need to get a check up to find out for SURE.

Trisomy is a form of aneuploidy where an organism has one extra chromosome in their genone (2n + 1). So a person with trisomy will have 47 chromosome (because a normal human has 46). A common example of trisomy is Down's Syndrome.\n\nThe n in 2n stands for the number of chromosomes in a haploid cell (a gamete, or 'sex cell') of that organism. So for humans it is 23 because a full set of chromosomes (2n) in a human is 46. It's more important to remember the 2n value of a species rather than the n value, which can easily be derived if you know 2n.\n\nMendel introduced the Law of Segregation and the Law of Independent Assortment using pea plants. Any half decent biology book can explain exactly what he did and how he derived these laws.\n\nCrossing over overs during metaphase of meiosis I (or metaphase I). More precisely, but probably not importantly, it actually occurs during prometaphase which is a phase between prophase and metaphase which was derived specifically to differentiate the process of crossing over from everything else which happens in metaphase. The teaching of prometaphase is inconsistent in courses so I would just stick with metaphase I for that answer.\n\nNondisjuction is when two chromosomes stay together instead of splitting up during anaphase, which results in the production of a cell with one extra chromosome and a cell with one less chromosome. This is the primary cause of Down's Syndrome which is related to maternal age, and other types of genetic diseases.\n\nMonosomy is the opposite to trisomy, that is, an organism has a genone with one less chromosome (2n - 1). It occurs just like trisomy. A human with monosomy will therefore have 45 chromosomes.

My guess is that they had first-trimester miscarriages.  It could just be coincidence.  It could also be that for whatever reason you have a relatively high number of defective sperm (no offense), or maybe your genetically defective sperm swim extra fast for some reason.  I'm just guessing here, but it seems to me that some individuals could be at a higher risk for nondisjunction events (when homologous chromosomes fail to separate) with results in trisomies and monosomies (the sperm has the wrong number of chromosomes, so the embryo has the wrong number of chromosomes).  Trisomy 21 causes Downs Syndrom, and I think there are one or two others that can result in full-term babies, but most of them self-abort in the first trimester.  If I'm right, it could also explain your fertility issues.  However, I want to make perfectly clear that this is just the speculation of a first-year bio major and shouldn't be taken as an authoritative answer!\n\nPS.  I think it's a really cool thing to have picked up on, and there's a very good reason your doctor didn't go into research. :)

We don't know and we will never know.  \n\nChromosomes are extremely fragile and will break down within a few days fo death at the very most. Since the last of the Neanderthals died over 30, 000 years ago it goes without saying that we don't have any Neanderthal chromosomes.\n\n>>>Secret Sauce, we have certainly extracted tiny FRAGMENTS of Neanderthals nuclear material. But they are just that, fragments a few hundred base pairs long. They are NOT, I repeat NOT, chromosomes. Chromosomes are far too fragile to survive.\n\nNote that your own article states that about 70, 000 base pairs have been recovered. To put that into perspective the shortest human chromosome has around 25 MILLION base pairs.\n\n70, 000 base pairs is not even close to being a complete chromosome even if it did all derive form a single chromosome, which it almost certainly did not.\n\nSo I repeat what I said  earlier: we don’t know and we will never know what the Neanderthal chromosome count was. Chromosomes are far to fragile to survive in a form that will ever allow a chromosomal count. The best we can hope for is a few tiny fragments of nuclear material that we will not be able to attribute to a specific number of chromosomes.
