Down Syndrome
What a difference an extra chromosome can make. Here we explore the misconceptions -- as well as the ups and downs -- of Down Syndrome, a congenital genetic disorder that is caused by the presence of an extra 21st chromosome. The affected person is mildly to moderately handicapped, short in stature, and has a flattened facial profile.

What is the role of a psw helping a child with down syndrome?
What is the role of a PSW helping a person with down syndrome
Do people with Down syndrome know that they have it?
yes they will be told by their parents when they are a little older, they function very well, and live and work in a productive manner, they have wonderful personalities because they always see the good in everyone and never the bad.
Does the inactivated X chromosome cause Down syndrome?
No, Down syndrome is caused by nondisjunction resulting in an extra chromosome in the 21st pair. An inactivated X chromosome (Barr body) is normal for all females. Females inherit two X chromosomes, and one is heavily methylated.
Can you develop Down syndrome later in your life?
I have a daughter with Downs and I have been told it is VERY PROBABLE...ask your pediatrician
There is research on that subject. It can be found in scholarly journals. The ones that I have read say that is is very possible and usually likely that a person with Downs will have a child that does not have Downs. Even two people with Downs are more likely to have a child with out it. Downs girls do get pregnant as easily as those without Downs. Downs teens feel all the same stuff the other teens do. Hormones, pleasure, ovulation. Their just not as equipped to control the baser instincts. That and not to mention the ugliness of molestations or sexual abuse - not all Downs kids are able to communicate effectively enough to tell when something bad is going on. There is also alot of debate about sterilizing Downs girls. Birth control is difficult or impossible to administer to those with profound Downs. Lots of really hard issues. My boyfriend has a Downs girl-13. She has had her period since she was 10. She still cannot change her own pad, and will leave bloody pads in my son's bathroom sink. It's pretty gross stuff for a 10 yr old and 13 yr old boy. Heck it's incredibly gross to me and I've had 4 kids!
What genectic disorder does Down syndrome involve?
Down Syndrome is when there is an extra chromosome in someones DNA. More exactly it is when the 21st chromosome has an extra one.
Trisomy 21 Down syndrome xxy kleinfelter syndrome and xo turner syndrome are all caused by?
Nondisjunction
-Trisomy 21(Down Syndrome) means there are 3 chromosomes on the 21st pair of chromosomes.
-Kleinfelters (XXY) means there is an extra chromosome on the 23rd pair(where the sex chromosomes lie).
-Turner Syndrome(XO) On the 23rd pair, there is no Y or second X chromosome. The female can survive with this.
When was Down syndrome first identified?
According to Columbia Encyclopedia, the symptoms of Down syndrome were "first described in 1866 by an English physician, J. Langdon Down."
Down syndrome - albeit without this particularly moniker - has been known for many hundreds, if not thousands, of years. It was usually called Mongolism in recent centuries in the UK.
Dr. John Langdon Down was the one who did much research on the subject, and the symptoms described by him have been renamed "Down syndrome."

Does Down syndrome affect you physically?
Yes it does, it affects the facial structures. In addition those who have down syndrome will have short necks, short arms, short legs, short toes, short fingers, and their joints show hyper flexibility.
Can a person with Down syndrome have normal kids?
That depends. Men with Down syndrome have been shown to be sterile, while women with Down syndrome are capable of carrying a child, with 50% likelihood that the child will be born with Down syndrome.
This is a particularly hard question to answer because of what you consider abuse. Abuse from a parent is when they take a belt, strap of any sort or an object to hit you with, or punching, kicking, scratching or slapping your face repeadedly. Taking priviledges away from you, telling you to live by the rules of the house or get out is NOT abuse. If you are failing school and they are making you study more and not allowing you out with friends IS NOT ABUSE. If you are doing drugs (not accusing you here) or drink too much (Not accusing you here either) then they have the right to lay down their laws of the house. Just because you are their child doesn't mean you shouldn't be expected to do chores around the house, follow their house rules and deal with it. This is not a free ride and a learning ground for you so you can become independent when you move out. If you give your parents respect then they should be giving it back. If you are truly being mentally abused (being called stupid, not allowed to attend school, making you look foolish all the time that's mental abuse.) If you are being kicked, punched, hit with a belt, or an object, repeadedly slapped in the face, scratched, etc., this is physical abuse. Spankings on the old butt (without an object and just an open hand) IS NOT ABUSE! If you are minor and abused you can report this to the police or Child Welfare and you will be taken out of the home. If you aren't telling the truth and you are just angry about having to follow house rules then you are in for a rude awakening. When Child Welfare comes into the picture not only can your parent be charged, but you will end up in foster care! Good luck Marcy
Ballots are usually organized from federal to local, so down ballots are just more localized contests that therefore appear lower on the ballot.
If a pregnant woman takes Procardia can this cause her to bear a baby with Down syndrome?
Down syndrome is a genetic defect and is the result of an extra chromosome at the time of conception. The use of Procardia (or any other drug) does not cause Down syndrome.
Why is an NSAID not recommended for someone who has Down syndrome?
The Huerta study looked at data on 228,660 patients collected in the United Kingdom from 1997 through 2000, Findings are that:
- Indocin tripled the risk of heart failure related hospitalization.
- Naproxin doubled the risk of heart failure related hospitalization.
- Ibuprofen (brand names include Advil and Motrin) increased the risk of heart failure related hospitalization by 43%.
As Down Syndrome patients are already an at risk group for cardiac arrest it is thought that the wise course is to avoid treatment with a drug that increases that risk. Gastrointestinal problems are also common to DS patients as well as considered a side effect of NSAIDS.
- The majority of Down syndrome cases are not hereditary. Only in cases of Translocation Down syndrome is this then possible. These inherited cases then occur because one of the parents is a carrier. A carrier will have 45 chromosomes instead of 46 but they will have all the genetic material of a person with 46 chromosomes. Remember that in Translocation Down syndrome the extra chromosome 21 material is located on a different chromosome. A carrier will have the extra material but will have only one chromosome 21. The carrier will not exhibit any of the symptoms of Down syndrome because they have the correct amount of genetic material. However, a carrier will have an increased chance of having a child with Down syndrome. If the carrier is the mother, the chances are approximately one in five of having a child with Translocation Down syndrome, but if the carrier is the father, the odds are 1 in between 20 and 50. In cases where the carrier has no unattached chromosome 21, all the carriers' children will have Down syndrome.
- The ability to have children varies among people with Down syndrome (generally they have a reduced rate of fertility). Down syndrome is also known as trisomy 21 and happens when you have three chromosomes instead of two on the 21st 'pair.' This happens when there is an error in cell division and instead of 46 chromosomes dividing into two new cells with 23 each, one of the new cells will have 24 (and therefore the extra '21' chromosome). So it's not really a hereditary thing -- the chances of giving birth to a child with Down syndrome increases after the age of 35 or so, and in general the odds are 1 in 800 of having a child with Down syndrome.
- It is mostly caused by an accident of gene formation. A small percent is hereditary.
- It is a genetic abnormality, but not inherited, per se.
How does Down syndrome occur with no history of Down syndrome in the family history?
It's either a mutation with the gene, or either the mother or father donates an extra chromosome.
2nd Answer:
True, and Down Syndrome is not a genetic disease and has nothing to do with family history.
By the way, the kind of chromosomal mistake that causes Down Syndrome occurs in many people, but on different chromosomes. Mostly, your body is so tolerant of this kind of mistake that you never see any results.
Does Michelle stafford kid have down syndrome?
Yes unfortunately the little Natalia has down syndrome, a frequent disease among children conceived after 40's or using eggs of an over 40's woman.
Which process could result in the type of cell mutation that causes Down syndrome?
Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).
