Is Down syndrome dominant or recessive?

Is Down syndrome dominant or recessive?

Neither: Down syndrome happens when an extra 21 chromosome is present in all the cells of the body. It happens before conception when the donor egg fails to shed one of its 21 chromosomes in the formation of the egg & the male 21 joins the female pair & creates an embryo with 3 number 21's. ...Read more

I was wondering is Down syndrome dominant or recessive?

I was wondering is Down syndrome dominant or recessive?

No autosomal: Down syndrome happens when an extra 21 chromosome is present in all the cells of the body. It happens before conception when the donor egg fails to shed one of its 21 chromosomes in the formation of the egg ; the male 21 joins the female pair ; creates an embryo with 3 number 21's. It has nothing to do with traits or mutations in the gene code. ...Read more

I am doing a presentation for my class on down syndrome and I need to know why it isn't dominant or recessive. P.S. I need a simplified answer

I am doing a presentation for my class on down syndrome and I need to know why it isn't dominant or recessive. P.S. I need a simplified answer

Seek info here: Lots of HT doctors have answered this for others - here's a start. Just dig a bit further, but it's a good reply.

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

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 more

Is gestational diabetes a dominant or recessive trait?

Is gestational diabetes a dominant or recessive trait?

Complex disease: Gestational diabetes (gdm), like type 2 diabetes, are related metabolic conditions with strong inherited genetic tendencies --- but multiple genes are involved in their expression (appearance in any person). So gdm is neither a dominant nor recessive trait. Whether a person gets gdm is also strongly impacted by age, weight, exercise levels, dietary factors, which are not genetically determined. ...Read more

Is having aortic valve regurgitation a dominant or recessive trait?

Is having aortic valve regurgitation a dominant or recessive trait?

Usually acquired: Aortic regurgitation is usually an acquired disease. Some forms of congenital vascular disorders are associated with aortic valve problems such as Marfan's Syndrome and this can involve the aortic valve. This is rare. Marfan's is inherited in an autosomal dominant pattern. Even more rarely it can also occur as a spontaneous mutation in someone who has no family history. ...Read more

What do you suggest if my grandmother and my mother both have tested positive for celiac disease. Is it a dominant or recessive trait?

What do you suggest if my grandmother and my mother both have tested positive for celiac disease. Is it a dominant or recessive trait?

Genetic: You may carry the gene for celiac- It is not a dominant or recessive gene. It is a gene that is associate to a chromosome that has been identified. In order to get the condition, you need to have the gene and an environmental trigger. You can be tested to see if you have the gene. The DR8 gene profile is seen in a large part of the population and may explain why celiac is being seen often. ...Read more

What is the difference between an autosomal dominant and autosomal recessive trait?

What is the difference between an autosomal dominant and autosomal recessive trait?

Input required: In dominant disorders, the dominant member of the gene pair controls how the gene activities are expressed, so the other gene can carry the same or normal information. In recessive disorders, the normal gene compensates for the bad information in the other gene, allowing a person to function normally unless both genes carry the bad information. ...Read more

How many ways can Down syndrome develop?

Extra 21 chromosome: The majority of Down syndrome develops when the fertilized egg gets an extra number 21 chromosome from the mother. When that cell divides and forms an embryo, every one of the cells in the baby's body have that extra 21 chromosome. There are rare cases where a baby inherits an extra part of the 21 chromosome from one of it's parents. The extra genes on the 21 chromosome cause the down syndrome. ...Read more

How can Down syndrome effect your health?

Every cell affected: Down syndrome is caused by having an extra copy of chromosome 21. Typically, this is caused by having three full copies of chromosome 21, also known as trisomy 21. Every cell in the body has an abnormal number of chromosomes, so it's easy to imagine that multiple organ systems would be affected. A valuable resource for Down syndrome health supervision is available from the aap. Www. Aap. Org. ...Read more

Do you think an adult could have mosaic down syndrome?

Do you think an adult could have mosaic down syndrome?

Accounts for 1% DS: Mosaicism is encountered in ds patients & I have followed one in the past. By definition, some tissues are composed of cells with normal information & other tissues have the abnormal, but the mix could vary greatly in the percentage of either. Functional outcome depends on that blend & whether the abnormally derived tissues compose critical structures like brain, blood, reproductive organs, etc. ...Read more
