What is the cause of too much iron in someone with Down syndrome?
One of the suppositions as to why iron might be harmful is based on the fact that people with Down syndrome have an excess amount of superoxide dismutase (SOD) in their cells, due to the extra 21st chromosome.

One doesn't "get" Down's Syndrome, it is a genetic anomaly. Predominantly, the older the mother, the more likely her child will develop Downs. Such children have similar features, such as ears too low, and tend to be clumsy and intellectually challanged. They also tend to be outwardly happy, and ver…y loving. (MORE)
Downs syndrome is in medical terms called Trisomy 21 as it is caused by a genetic defect in the 21st set of chromosome, usually you have 44 chromosomes - 22 from your mother and 22 from your father and a set of sex chromosomes (these are your male/female genes), if you have Down Syndrome you have an… extra chromosome on the 21st set of genes so instead of 1 from each parent you have 1 from you dad, 1 from your mum and a mutated gene.

47 There are 47 chromosomes in someone with Down syndrome; the 21st pair has an extra chromosome. Most people have 46 chromosomes. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes on their 21st pair.
Having an extra copy of chromosome 21. You are supposed to have 2; when you have 3 (trisomy 21), Down's Syndrome is the result.
During meiosis homologous chromosomes are separated and only one copy of each chromosome goes into the gamete. If they aren't separated correctly, both copies may go into the gamete. After fertilisation, the embryo will contain 3 copies of that chromosome. If this occurs with chromosome 21, it will …result in Down Syndrome. (MORE)
Trisomy 21. An individual has 3 copies of the 21st chromosome instead of the normal 2.
\n. \nPatau syndrome is a very rare syndrome caused by a problem in the chromosomes, the structures in the body's cells that contain DNA. The specific chromosomal problem in Patau syndrome is that the cells have three copies of chromosome 13, as opposed to the usual two copies in most people. Becau…se there are three copies of chromosome 13, the condition is also called trisomy 13. The cause of Patau syndrome is similar to Down syndrome. Like Patau syndrome, Down syndrome is caused by having an extra copy of a certain chromosome. Individuals with Down syndrome usually have an extra copy of chromosome 21. Thus, Down syndrome is commonly called trisomy 21. Perhaps not surprisingly, the cause of the trisomy in both Patau and Down syndromes is similar. A phenomenon called nondisjunction is responsible for most cases of trisomy 13 and 21. Nondisjunction is an error that can occur during cell division (specifically the cell division process called meiosis). Rather than splitting evenly, cells that have undergone nondisjunction typically split unevently into two cells; one cell receives one extra copy of a chromosome, while the other is deficient in the chromosome. A major risk factor for nondisjunction is advanced maternal age. The chance of nondisjunction increases significantly once mothers are 35 years old and greater. As you'd expect, the risk of Patau and Down syndromes increases considerably with advanced maternal age.\n. \nTo view photos of children Living with Trisomy 13 - Patau Syndrome http://www.livingwithtrisomy13.org (MORE)
Down's sydrome is caused by trisomy 21, when there are three 21st chromosomes instead of the normal two.
Mostly people with Down Syndrome have heart problems. But they could have problems with anyuthing because everyones diffrent.
No, Down syndrome is a genetic disorder , and occurs because of the presence of an extra chromosome, not due to smoking. The chances of a women giving birth to a Down syndrome baby increases with age.
Not sure if that is a known side effect, but I have been on Foltrin for about 2 months now for anemia, and it is giving me killer headaches. I stopped taking it and going to my doctor tomorrow.
No. However smoking during pregnancy can cause a number of other pregnancy complications. Women who smoke during pregnancy are at higher risk for ectopic pregnancy, miscarriage, preterm labor, placental abruption, and stillbirth. Babies born to mothers who smoked during pregnancy have greater risk o…f withdrawal symptoms, low birth weight, prematurity, lung issues, cleft lip and palate, and neurological issues due to lack of oxygen.

Down Syndrome (aka trisomy 21) is caused when an extra chromosone number 21 is present. Normally, each cell in your body has two copies of each of the 44 regular chromosomes, one X and another X (in women) or a Y (in men). When sperm and eggs are formed these pairs line up and then are divided into… two sets of 23 chromosomes, one of each. In the most common form of Down Syndrome the pairs of chromosone 21 do not seperate making a sperm or egg with two and another with none. If the sperm or egg with two participates in ferilization the result is a cell with 3 chromosome number 21's (2 from one parent and 1 from the other). This type tends to happen more often as women get older. It is not nearly as strongly related to the age of the father. In a less common form one of the parents has a chromosome 21 that is duplicated and stuck to itself and so twice as large (a Robertsonian translocation). The person with this defect may be an apparently normal carrier but produce children (and grand children) with Down's. (MORE)
You cannot do anything to cause your child to have Down Syndrome, drinking,smoking etc in pregnancy does not cause this. Down is caused by a genetic oops where there is an extra chromosome. It is present from the time of conception. You cannot catch Down syndrome.

Down's Syndrome is caused due to the presence of an extra 21st chromosome, resulting in 3 sets of 21st chromosome instead of just 2. This is because during Anaphase II of Meiosis II non-disjunction occurs and instead of one 21st chromosome going into each gamete, both go into one of the gametes and …none goes into the other. When a normal gamete fuses with the gamete with an extra21st chromosome, it forms a zygote with 3 sets of 21st chromosome instead of 2 and that is known as Down's Syndrome. (MORE)
The cause of Down syndrome is one of three types of abnormal cell division involving chromosome 21. All three abnormalities result in extra genetic material from chromosome 21, which is responsible for the characteristic features and developmental problems of Down syndrome. The three genetic variati…ons that can cause Down syndrome include: . Trisomy 21. More than 90 percent of cases of Down syndrome are caused by trisomy 21. A child with trisomy 21 has three copies of chromosome 21 - instead of the usual two copies - in all of his or her cells. This form of Down syndrome is caused by abnormal cell division during the development of the sperm cell or the egg cell. . Mosaic Down syndrome. In this rare form of Down syndrome, children have some cells with an extra copy of chromosome 21. This mosaic of normal and abnormal cells is caused by abnormal cell division after fertilization. . Translocation Down syndrome. Down syndrome can also occur when part of chromosome 21 becomes attached (translocated) onto another chromosome, before or at conception. Children with translocation Down syndrome have the usual two copies of chromosome 21, but they also have additional material from chromosome 21 stuck to the translocated chromosome. This form of Down syndrome is uncommon. There are no known behavioral or environmental factors that cause Down syndrome. (MORE)
you can tell because of their face and actions. their face might have slight differences that a normal face would. for example the eyes would be closer together and their face would be very flat. their posture would also tell.
no it's not caused by smoking or drinking it is caused by an extra Chromosone well an extra 21 chromosone . your suppose to have 23 pairs chromosones 23 from your dad 23 from your mom But down syndrome babies get 2 4 from one parent and 23 from another parent!!!!
Haemochromatosis (see Wikipedia), liver diseases,... Mostly genetic, with certain racial proclivities, but most anaemias are actually iron-loading. Most males have too much iron in their blood, which is a factor conducive to heart attack. Probably, in robust times, bleeding wasn't always such a bad …idea. It is still done for those with haemochromatosis. The problem is that iron is stored in the body, and difficult to eliminate. Especially the more easily absorbed heme iron from diets rich in meat. Cooking acidic foods in iron pans can result in hyperferraemia (excess iron). Multi vitamin/mineral tablets for men are now made, containing no iron. One should never take iron tablets without a serum blood test; it is no more a 'wonder food' than say magnesium or calcium. There are good plant sources, and whilst soils may have too much or too little, supplementation should not normally be necessary. (MORE)

I have a 4-year-old son with Down syndrome. "Special needs" is just a way of saying that the person with the disability will need extra attention in every aspect of their lives. For example, early intervention in babies and young children with "special needs" is always good. It helps them get sta…rted in learning and/or experiencing life. Kids with Down syndrome learn slower than typically advanced people. Yes, they need help with learning, but that does not mean that they do not learn at all. =] There is no list of "special needs," but rather that everything requires extra attention and help. (MORE)
uh... no not at all its a sort of mutation with the gene. the chromosones split up and the red ang green segmet of chromatids switch 1 chromatid
A person with Down Syndrome may find they have a short attention span, poor eye sight and a need for a routine. Also, typically the life span of a person with Down Syndrome is cut short at an average of 49 years.
People with Down syndrome have an extra copy of chromosome 21 in every cell. Down syndrome most often occurs when chromosomes fail to separate properly during meiosis, when sex cells form. Hope this helps!!
No. Down syndrome is caused when a person inherits three copies of chromosome 21 instead of two.
Down Syndrome is a genetically-transmitted disease cause by the presence of part or all of an extra 21st chromosome. We can't blame this one on the drugs. However, drug use (incoluding alcohol) while pregnant could complicate the issue with developmental problems. I always remind people that if t…hey use drugs during late-stage pregnancy, the child will be born with an addiction. Whether or not its later life is affected, the baby will have to withdraw from the drug during the first few days of life. Hell of a way to start your presence on the planet, wouldn't you say? (MORE)
Downs syndrome is caused by a genetic mutation called trisomy. Trisomy is when an extra chromosome is present on one set of chromosomes, so instead of the 46 chromosomes of a normal human there are 47. Trisomy can often result in miscarriage as the body cannot cope well with extra chromosomes. Downs… syndrome is when there is an extra chromosome 21. Other genetic defects which are caused by trisomy are Edwards syndrome and Patau syndrome. (MORE)

Natural light produces vitamins D and C. Vitamin D in light is known to improve brain functioning in persons with down syndrome.
the disease would be caused by the presence of all or part of an extra 21st chromosome.
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
Mistakes in meiosis may cause Down syndrome. The error happens whenthe chromosomes segregate into the gametes. The egg or sperm mayhave too many or too few chromosomes. Down syndrome has an extrachromosome in the 21st pair.
Down syndrome is caused by an additional copy of chromosome 21. There is not a specific "gene" that causes it, the additional copy of the chromosome leads to other changes and processes that result in the condition. It is not dominant or recessive.
No. Someone with Down's syndrome could also happen to have epilepsy, but if they do it isn't always to do with the fact that they have Down's Syndrome.

There are three possible causes: 1) The human genepool is beginning to stagnate, which could end in the extinction of our species. 2) Women wait until later in life to get pregnant, which makes birth defects more likely. 3) Increased drug and alcohol consumption (need I say more?)
The causes and risks factors are maternal age. Have babies at early age as the risks increases with age. About 1:2000 live births in age 20 to 1:300 at age 35 to 1:40 at age 45..
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. .

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. (MORE)
There are many causes for Down Syndrome. One of the cause is: Nondisjunction : The body's cells contains nucleus which has 23 pairs of chromosomes; the nucleus is storage for genetic material (genes). The occurence of Nondisjunction is mainly caused by an error in cell division and an embryo ends u…p with three copies of chromosome 21 instead of two. In conception the 21st chromosome in a sperm or egg can have an abnormal cell division and as the embryo grows the additional chromosome maybe copied to the rest of the body's cells. Nondisjunction mainly causes Down syndrome type called Trisomy 21. The risk of nondisjunction in women increases as age passes. (MORE)
