What Chromosome Is Affected By Down Syndrome
How do I make a punnutt square for Down Syndrome. Yes, it's a chromosome defect, but it can also be inherited. answer asap. Thanks!
Down syndrome is a genetic condition in which there is an extra chromosome present. Symptoms may range from mild to severe. Children with Down syndrome share a common physical appearance including a flattened nose, small ears, a small mouth, upward slanting eyes, and a single crease in the ...Read more
Not mutation,number : Down syndrome is an abnormality of chromosome numbers, not a trait or mutation in the gene code. During conception only one of chromosome of each pair is given by both parents to the fertile egg.If a parent adds their 2 nbr 21chm to the other parents nbr 21, 3 end up in the egg ; the excess 21 causes the all the problems.Rare forms are causes by a extra piece of a 21, but that's another issue. ...Read moreGet help from a doctor now ›
What would be a good way to cure down syndrome? What would be a way to remove the extra chromosome from every cell in the body? I need a good idea. Thanks :)
It : It is true that there is no such treatment today that would allow to remove an extra chromosome from every single cell in the body. However, for someone who is looking for ideas, there are several to explore. One idea would be to use antisense oligonucleotides to reduce expression of certain genes in the additional chromosome. This approach has been gaining momentum lately and there are already two or more antisense oligonucleotide-based drugs that have been approved by fda. An example of genes that could be targeted with antisense in down's syndrome could be the gene responsible for the amyloid production. It is known that patients with down's syndrome develop significant amyloid deposits early in their lives. These deposits (they are also found in alzheimer's disease brains) impact overall function and quality of life of these patients. One could expect that reducing amyloid deposits related to the extra chromosome could improve their quality of life. There are many sources of information on antisense oligonucleotide technology and wikipedia is one of them. ...Read moreGet help from a doctor now ›
Why do Down syndrome patient have their eyes slanted upward, is it caused by the chromosome 21, i need an explanation on why their face look different?
In the genes: All of our features are determined by our genes. The appearance of your eyes, nose, mouth, hair color, skin color, among other features are all inherited. When there is a defect in the gene coding, changes can occur. Facial features can change with in utero exposure such as alcohol (fas syndrome). For downs, the extra 21 causes low ears, slanted eyes, simian crease as well as organ problems. ...Read moreGet help from a doctor now ›
What are the chances my child will be born with chromosomal abnormalities? I was told my unborn child has echogenic bowels, that i tested higher for the risk of Down syndrome and as a carrier of the cystic fibrosis trait
There : There are several ultrasound findings that can suggest down sysndrome, and echogenic bowel is one of them. There could be other explanations for that finding, though. It sound like you will need some testing to find out what's going on. The two tests used most commonly are amniocentesis and chorionic villous sampling. Each has its own risks and benefits, so you should discuss them with your obstetrician. I would suggest that you do this sooner than later, and regardless of whether the outcome might lead you to terminate the pregnancy. ...Read moreGet help from a doctor now ›
Confusing question: Every cell of the nervous system has the ds chromosome pattern so the point of your question is confusing their brain acquires & processes information in a qualitatively different way. They acquire words/language & developmental milestones later. If you have a more specific question, start over & define it clearly. ...Read moreGet help from a doctor now ›
