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.

Asked by Wiki User

A new test has been developed, called FASTER (First and Second Trimester Evaluation Risk), with which Down syndrome will be able to be detected during the first trimester of the pregnancy - about 11 weeks after conception - with 87% accuracy.

Where can you find information about someone who has both Down syndrome as well as Klinefelter's syndrome?

User Avatar

Asked by Wiki User

Causes of Klinefelter Syndrome

The additional sex chromosomes in men with Klinefelter syndrome results from nondisjunction during meiosis and may have a paternal (50 to 60 percent) or maternal (40 to 50 percent) origin. This contrasts with Down syndrome, which is caused predominantly by maternal nondisjunction and inheritance of the extra chromosome 21 from the mother.

How do you receive down syndrome?

User Avatar

Asked by Wiki User

The cause of downs syndrome is a process called disjunction.In this process the two copies of chromosomes 21 fail to separate during the formation of egg, resulting in the formation of egg having two copies of chromosome 21.. when this egg gets fertilzed, the resulting baby ends up havng three copies of chromosome 21 in each cell... however the cause for this disjunction is not known...

Where did down syndrome come from?

User Avatar

Asked by Wiki User

Downs syndrome is a genetic abnormality caused by an extra chromosome, in simple terms - as a healthy individual you inherit 22 chromosomes from your mother and 22 from your father, so that's 44 altogether, 1 chromosome from each of your parents will combine to form 22 sets, in a person with Downs syndrome there is an extra abnormally shaped set of chromosomes. So in short a person with Downs syndrome has 23 chromosomes instead of 22.

Does the man age determine downs syndrome?

No, not the father. But older mothers have a higher rate of bearing a child with Down syndrome.

Because some doesn't want to keep it if it has it. It is not like raising a ordinary child but this one will have special needs.

Can downsydrome be detected before birth?

User Avatar

Asked by Wiki User

Down syndrome in a baby can be identified with amniocentesis during pregnancy or at birth. See more in related link.

Answer

Amniocentesis is a procedure performed on pregnant women to determine possible risk factors with their developing fetus. A long needle is inserted through the abdomen into the uterus, being guided by an ultrasound, that extracts amniotic fluid. This amniotic fluid is then further tested to determine certain risks such as Down syndrome. Although amniocentesis does have it benefits of obtaining this kind of knowledge, it also poses threats to the fetus such as a .8% chance of miscarriage, clubfeet, trauma to the mother, preterm labor and an infection of the uterus.

According to an article published in a Canadian journal, a study in Canada showed that amniocentesis performed between weeks 11 and 13, resulted in 29 out of 4,374 women gave birth to children with clubfeet. Because of this risk, doctors generally try to avoid performing amniocentesis before week 15 of pregnancy.

A safer diagnosis of Down syndrome would be through blood screenings. The mother's blood must be drawn then the sample will be sent to a lab for further testing and possible diagnosis. The first screening is generally done between weeks 11 and 13. A second screening is done between week 15 and 20 of the pregnancy. According to the March of Dimes, karyotyping done through prenatal blood screenings cannot diagnose syndrome of the fetus but they can show whether or not the risk is high or low. Although karyoptying is not as accurate as amniocentesis, it is less invasive and poses no harm to the mother or the fetus.

Because Down Syndrome causes certain physical changes that we notice more than the person underneath. Down children all resemble each other because of the effects of the disorder, but they do not all look the same.

If you have some sort of mental retardation does that mean you have Down syndrome?

User Avatar

Asked by Wiki User

No. Down's is only one of millions of reasons to become retarded. While it used to be thought that only children with Down's were the only ones who were mentally retarded, it is now known that Down syndrome is only one of the hundreds of known causes of a child being mentally retarded.

It's even been documented that one-third of the children who are mentally retarded have no known cause.

Two other major known causes are Fragile X and Fetal Alcohol Syndrome Disorder. Like Down syndrome, Fragile X Syndrome is a chromosome abnormality.

However, FASD is not a chromosome abnormality. FASD is the only preventable -- 100% preventable -- cause of mental retardation. It is also the only one that is 100% untreatable. It's actually been estimated that FASD affects 40,000 infants each year. That is more than Spina Bifida, Down syndrome and Muscular Dystrophy combined.

Lots of research is being done endlessly -- with parental education being the most important.

How were people with Down syndrome treated back in the day?

User Avatar

Asked by Wiki User

It depends where in the world they were. It ranges from living a dejected/shunned life to complete cure. Some places it was not tolerated, in others cured.

There are certain ancient practices which allow for easy treatment. It is said that most of the autistic cases are past life trauma. People knowledged and proper practitioners were able to assist those in need during the earlier days.

That true knowledge is mostly lost and fewer know it today. Hence modern medicine.

The reasons for autism consist a wide area. It can be for myriad reasons. Trauma is a prominent one. Dejection is another.

Treating autism in childhood is the best option. As the individual grows, patterns:- mental and physical get set and become harder to resolve. At that stage more serious medication will be needed. During childhood however, many a time it can be accomplished using no such or bare minimal medication.

In the earlier days people only had what was on hand. This day of information was not available to them. So they paid more attention to their surroundings and did what they could, if they could gather a solution they did. If they could not they let live.

Also, in earlier years experienced autism was one-forth of what it is today.

No, Down syndrome is not contagious. It is a genetic/chromosomal difference - some may equate it to a birth defect, others to a birth enhancement
