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

Down's syndrome: Delayed maturation of brain & body, result in small chin, oblique eye fissures with skin folds on inner corners of the eyes, flat nasal bridge, poor muscle tone, protruding tongue, flat face, short neck, lax joints, larger space between big toe & second toe, short fingers, short stature & bowed legs, obesity as they grow older. ...Read more

What are the symptoms and treatments of down syndrome?

Long story!: The problem is duplication of genetic material (chromosome 21) in every cell of the body. There are facial features, heart problems, reduced muscle tone, and spinal, gi, ent, thyroid and blood-related issues as well. The biggest issue is mental deficiency. Ongoing surveillance and intervention by your pediatrician are important. So is developmental and school-based help. ...Read more

See NIH website: See: www. Nchi. Nlm. Nih. Gov/pubmedhealth/pmh0001992/ for a full review.
Down syndrome results when a kid is born with too much chromosome material in his/her cells which confuses the system & results in anomalies & poor development. It cannot be fixed, but outcome can be improved with attention to associated problems. ...Read more

What are the fetal sign and symptoms of down syndrome?

What are the fetal sign and symptoms of down syndrome?

Maternal serum: Screening at 10-14 weeks + fetal ultrasound (fus) at 11-14 weeks + maternal "quad" screen at 16 weeks detects ~ 95% of fetuses with Down syndrome with <5% false-positive rate. Increased size of the fluid-filled space at the nape of the neck & abnormalities of blood flow in the heart are signs on early fus. Diagnostic testing is chorionic villus sampling at 10-12 weeks or amnio at 15-18 weeks. ...Read more

How to know if the baby is Down syndrome or mosaic down without blood test?

How to know if the baby is Down syndrome or mosaic down without blood test?

Why do you ask?: You're going to need labs to determine this. Please forgive my frankness. Having a child with possible Down's is an extremely serious business and anyone who would trivialize this by saying, "Let's skip the labs that will establish the diagnosis" is doing both the child and the family a grave disservice. ...Read more

Is there a type of mosaic Down syndrome that doesn't require the mutation to come from either parent to have a downs child?

Yes: A mosaic Down syndrome child can come from a normal egg and normal sperm, produced by normal parents. The fertilized egg would start out normal with 46 chromosomes. It can divide into 2 normal cells, which themselves divide again. If on one of the early divisions, one cell ends up with an extra #21 chromosome and survives to continue dividing, the child will be mosaic with some trisomy 21 cells. ...Read more

Multiple symptoms: Down syndrome can have multiple congenital heart disease which includes atrial septal defect, hypoplastic left ventricle, tetrology of fallot, transposition of great vessels and ventricular septal defect. Some defects can have very few or no sign and symtoms while other may have bluish tinted nails or lips or fast or trouble or others may tire easily when feedind, or to be very sleepy. ...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

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 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

What causes down syndrome?

DNA defects: Chromosome 21 seems to be the cause. Two most common types are trisomy 21 where ther is an entire extra chromosome in each cell. The other is translocation where only an extra piece of the chromosome is found. It can be an isolated defect or an inherited defect. Rare exotic forms include polyploidy and haploid forms and chimeras. Sorry you asked? ...Read more

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 treated?

Down syndrome: Down's syndrome may be detected before birth (prenatally) or after birth (postnatally). It cannot be cured but treatment and support can help someone with Down's syndrome to lead an active life. A number of advice and support groups are available for people with Down's syndrome and their families and carers. ...Read more

Why does Down syndrome happen?

Mistake in chromosom: During the formation of normal eggs or sperm the chromosome (c) pairs are supposed to split leaving one of each in the egg/sperm. At conception the joining of egg/sperm brings together the pair & as tissue grows it has the proper number in each cell. With ds the egg has a pair of 21c and at conception a triple 21 is created. All cells derived after will have an extra 21 & become a ds child. ...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

How can you inherit down syndrome?

Depends on parents: An unaffected mother or father could have a balanced (normal) set of chromasome material where a piece of one 21 chromasome is stuck on another. If the egg or sperm had the normal 21 and an extra 21piece hidden on another chromasome, they could pass it to the baby. It only takes an extra piece of 21 to cause ds. It is important to study ds to verify type, as translocation ds can recur each pregnany. ...Read more

Down syndrome is autosomal dominat?

Down syndrome is autosomal dominat?

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
