What's the relationship between trisomy 21 and down syndrome?

What's the relationship between trisomy 21 and down syndrome?

Name game: Dr.Langdon Down worked at a home for the retarded in Britain in the 1800's.He was credited for the first published description of the syndrome that would carry his name. After the human chromosomes were identified and numbered in the 1950's, DS was studied and trisomy 21 was identified in most. Later studies show an extra piece of a specific area of the 21 is all that is needed to have DS. ...Read more

Is Down syndrome sex linked/recessive/or dominant?

Is Down syndrome sex linked/recessive/or dominant?

None of the above: 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

Is Down Syndrome a sex linked chromosomal disease?

Is Down Syndrome a sex linked chromosomal disease?

No: Down syndrome is an abnormality of chromosome numbers, not a mutation on a sex chromosome. During conception only one of chromosome of each pair is given by both parents to the fertile egg.If a parent adds their 2 # 21 chm to the other parents # 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 more

Why is Down syndrome more maternally inherited?

Why is Down syndrome more maternally inherited?

It isn't...: Maternally inherited, unless the mother has down's syndrome. Inherited means it's passed from generation to generation. When down's occurs, the egg has two copies of chromosome 21 instead of the usual one copy, so when the egg is fertilized, it ends up with three copies instead of the usual two. This is a new event, not an inheritance. The risk of down's syndrome increases with maternal age. ...Read more

Is XXY klinefelter's syndrome related at all to marfan's syndrome?

Is XXY klinefelter's syndrome related at all to marfan's syndrome?

No: The two syndromes have some similar features, but they are different syndromes that are unrelated. Klinefelter syndrome is caused by ahaving at least one extra x chromosome in a person who has a y chromosome (normal male=46 xy, klinefelter=47xxy). Typical marfan syndrome is caused by a mutation in fbn1, coding for fibrillin-1. ...Read more

How will having goodpasture syndrome affect me down the road?

How will having goodpasture syndrome affect me down the road?

Depends on the case: Assuming it is cured, recurrence is always possible. Need to be attached to your nephrologist for long years for follow up. However, if not cured you expect dialysis if kidneys fail. Either case you need to keep an eye on lungs, cough and shortness of breath, since disease may affect them too. ...Read more

Can shaken baby syndrome reflect underlying emotional problems in the parents?

Can shaken baby syndrome reflect underlying emotional problems in the parents?

Anger management: The degree of shaking necessary to damage a baby is quite severe and must occur repeatedly to be really damaging. Most new parents can be angry with the baby, but will easily diffuse the anger and avoid injury to the child. Normal play and enthusiastic handling of the baby will not produce brain damage. ...Read more

What is down syndrome?

What is down syndrome?

Chromosome defect: Ds is one of the more common chromosome(c) defects that can survive pregnancy (many others miscarry).Eggs are supposed to have a single 21c & combine with the 21 from dads normal sperm.Here a pair of moms 21c +dad's 21 creates a baby with the extra 21c in all tissues.This extra material confuses the creation of body parts causing ds..Various prenatal tests can pick up signs early on. ...Read more

Can you tell me how can the chromosomal conditions , trisomy x, xyy syndrome and turner syndrome differ?

Can you tell me how can the chromosomal conditions , trisomy x, xyy syndrome and turner syndrome differ?

Good online sites: Xxx and xyy have relatively little impact on those who have them and are usually incidental findings -- this is actually true despite the hoopla over xyy. I have three physician colleagues who have turner's xo and do fine. http://ghr.nlm.nih.gov/ is really good (thanks uncle sam). ...Read more

Are my parents the reason I have aspergers? Is asperger's syndrome inherited from your parents?

Are my parents the reason I have aspergers? Is asperger's syndrome inherited from your parents?

Partially perhaps: Scientists have long suspected that there are genetic and environmental components to asperger syndrome.A specific gene for asperger syndrome, however, has never been identified. Instead, the most recent research indicates that there are most likely a common group of genes whose variations or deletions make an individual vulnerable to developing asd. Environmental factors undoubtedly also play a role. ...Read more
