Is Down syndrome inherited?

Is Down syndrome inherited?

Not usually: The only way to inherit down syndrome is if one parent has down syndrome and passes 2 copies of chromosome 21. Few people with ds reproduce, so that is not usually a factor. ...Read more

How is Down syndrome inherited?

How is Down syndrome inherited?

Rarely: Downs syndrome is usually related to a trisomy defect that develops during the initial cleavage of the cells during primary fetal development. A form can occur as a translocation that may be carried by a parent. An assumption is that the 21 chromosome may be damaged by maternal age or by some environmental factor that then results in downs syndrome. Most cases are just by chance. ...Read more

Could scoliosis slow down growth?

Could scoliosis slow down growth?

Sometimes: If you mean ultimate height achieved, the answer is possibly. The more severe scoliosis reduces height because of contraction by degree of curvature ( curvature vs straight line). ...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

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

Short leg syndrome | short leg proportional to other. Is it genetics?

Short leg syndrome | short leg proportional to other. Is it genetics?

Almost always not: Even if an entire leg is bigger, or half of the body or facial structures, we do not het know what courses them. Be sure to exclude unilateral congenital dislocation the hip. If the foot is bigger, there is a wonderful organization which matches mirror images of feet. If child A has a size 8 right foot and a size 7 left foot, they find child B with a size 8 left foot and a size 7 right foot. ...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

Can sleep positions affect height? Does sleeping w/ 1 leg bent in fetal position or legs straight (feel bit pulling behind knees) add height in adults

Can sleep positions affect height? Does sleeping w/ 1 leg bent in fetal position or legs straight (feel bit pulling behind knees) add height in adults

Not really: Any comfortable sleeping position may be used, and none of the positions add height more than any other position. All the comfortable positions will add the same slight amount of height, because weight is taken off the spine during sleep (the vertical downward force of gravity is not acting vertically upon a person's spine, during typical sleep in a bed). The effect goes away, when one stands up. ...Read more

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 fragile x syndrome the same degree of retardation as down syndrome?

Is fragile x syndrome the same degree of retardation as down syndrome?

Variable: They are both "genetic" conditions but they are different in the spectrum of issues they present-. People with fragile x may have subtle cognitive impairments all depending on how affected the fmr1 gene is. People with downs have an extra chromosome and kids have delayed cognition as well as physical growth and frequently heart problems.. They both may exhibit autistic traits, more so fagile x. ...Read more

How can Down syndrome effect your health?

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

Can you please define Down syndrome inheritance pattern ?

There is none: You do not inherit ds from your parents in the traditional dominant or recessive fashion. During formation of the egg, only one of a pair of the 23 separate chromosomes is present so the sperm bringing 23 will reestablish the 46. Ds occurs when an extra 21 (or piece of a 21) is present in the egg after conception. This is a chromosome number change, not an inherited trait. ...Read more

Do Down syndrome babies grow at a smaller rate in womb?

Do Down syndrome babies grow at a smaller rate in womb?

No: They tend to grow at a pretty normal rate prior to birth. Deficiencies in linear growth will eventually occcur in the average ds kid as they grow older. However, some maintain a relatively normal rate of growth, dependingg on other factors affecting their health. ...Read more

Can gilbert's disease slow down metabolism of meds?

Can gilbert's disease slow down metabolism of meds?

No.: Gilbert's "disease" is a genetic anomaly in which there is a reduced ability to clear bilirubin from the body. This occasionally produces a visible excess of bilirubin in the body during times of increased bilirubin production. This does not affect the clearance of medications. ...Read more
