Can two parents with down syndrome give birth to a normal child? Please explain

Wouldn't happen: Although DS girls enter puberty and become fertile the male rarely if ever achieves this status. DS females have offspring after conception by normal males, usually from abuse or incest. These are roughly half normal and half DS. Males with DS rarely if ever achieve a fertile status and because of this outcome would be unknown if ever conceived.

At 37, I had two miscarriages for my second child. Does it mean if I get pregnant again my child will have down syndrome?

At 37, I had two miscarriages for my second child. Does it mean if I get pregnant again my child will have down syndrome?

Risk is elevated: As a mother's age increases, the risk of having a child with Down syndrome increases. You can address this with you OBGYN. If you become pregnant, there is a new blood test for Down syndrome which is non invasive compared to amniocentesis.

Why is there a 50% chance of a woman with Down syndrome producing a normal baby?

Why is there a 50% chance of a woman with Down syndrome producing a normal baby?

Laws of genetics: When a woman with Down's Syndrome forms gametes (unfertilized eggs), all the chromosomes except #21 will split evenly. Since Down's Syndrome means three copies of chromosome 21 (by dehfinition), the chromosome cannot split "evenly" - half will have 1 copy (normal); the other half will have 2 copies (Down's syndrome carrier). These will pair with 1 copy (usually) of Chromosome 21 from the father.

My sister has a two yrs old Down syndrome boy. What is the chance that a second baby is also affected? Is there chance to reduce the risk?

My sister has a two yrs old Down syndrome boy. What is the chance that a second baby is also affected? Is there chance to reduce the risk?

Depends: Traditional ds (>85%) have an extra 21 chromosome & recurrence risk runs 1% for young mothers but 1% + the age factor as a women ages. There are uncommon forms of ds due to transfer of pieces between chromosome where the mom or dad could be an asymptomatic carrier. The % of those varies with the defect & it would be best to consult a geneticist. If regular ds, the numbers above apply.

Could you tell me what happens when two Down syndrome people have a baby?

Could you tell me what happens when two Down syndrome people have a baby?

Seldom happens: Most down syndrome males are functionally sterile. Rare mosaic individuals have potential for fertility but data is not available for comprehensive review. Ds women enter puberty & childbearing at the usual time & can give birth. Data suggests less than 1/2 their offspring will be ds due to miscarriage of some ds embryos. Most are born prematurely and by c-section.

Need help docs! My baby is 13 months old don't have any teeth he is Down syndrome is that normal?

Perfectly normal: Eruption patterns vary widely from child to child, and it is not uncommon for some children to start the process later than others. There is nothing you can do to speed up the process.

Is fetal movement of baby with any 'problem/defect' like down syndrome, the same as a normal growing fetus?

Is fetal movement of baby with any 'problem/defect' like down syndrome, the same as a normal growing fetus?

Depends on the: Degree of low muscle tone (hypotonia) that is present in a fetus with down syndrome ; the size (smallness for gestational age) of the fetus. Some mothers of infants with ds say they felt less fetal movement than from their non-ds fetuses; others say their fetus with ds was a good " kicker." there is a range of hypotonia in infants with ds, just as there is a range of cognitive ability.

Tips for mentally stimulating a child with down syndrome?

Tips for mentally stimulating a child with down syndrome?

Early Intervention: Programs for infants with DS accelerate attainment of motor, communication, self-help/adaptive & cognitive skills through OT, PT, cognitive, behavioral & Speech/Language Therapy from 0-3, then Early Childhood Special Education beginning at age 3 + individual therapies, if possible. Ask teachers & therapists what skills your child has mastered, what he's ready to do next & how to motivate him.

How can you find out for sure if your child has down syndrome?

Why are women 35 years old and older more prone to getting a Down syndrome child?

Why are women 35 years old and older more prone to getting a Down syndrome child?

Egg injury: A newborn girl is born with all the eggs she will ever have, and their quality reflects exposures to toxic agents throughout life. Men get more of a pass on this because they make millions of sperm and the healthiest sperm swim faster and do the fertilizing. We know that over 35, the chances of DS begin to rise, reaching 1/5 by age 55.

If there is no sign of Down syndrome in my family, what are the chances I will have a child with downs?

If there is no sign of Down syndrome in my family, what are the chances I will have a child with downs?

Getting higher: These risks are basically related to age. As you pass 40 it hits 1% and by 45=2% and after 50 as much as 5%.You must add that to the 4% baseline every pregnancy faces. There are screening tests that help yu know ahead of time that a problem is coming.

What are some of the causes for a child to be born with down syndrome?

What are some of the causes for a child to be born with down syndrome?

Several possible: The features of down syndrome are dependent on the addition of one extra segment of a 21 chromosome which is more likely as women age. You can get this several ways. The traditional DS (~95%) has 3 copies of a 21 chromosome. About 4% have the specific extra 21 piece stuck on a regular chromosome (trans-location).About 1% have a mosaic of some normal and some 21 trisomy in variable amounts.

What percentage of people have an abortion when they know their child will have down syndrome?

What percentage of people have an abortion when they know their child will have down syndrome?

Difficult # to find: The biggest influence on the decline of down syndrome births in the last 4 decades has been the introduction of oral contraceptives & or decision to undergo permanent sterilization. Many centers do not keep or record the reasons for the procedure. Some centers consider invasive sampling such as amniocentesis only if couples are likely to terminate even if screening tests were suggestive of ds.

If I have some of the physical signs of Down syndrome like a simian crease but don't have down syndrome, am I more likely to have a child with downs?

If I have some of the physical signs of Down syndrome like a simian crease but don't have down syndrome, am I more likely to have a child with downs?

No: Some of the features seen in down syndrome persons are also seen in other hereditary disorders, and some features are seen in normal people. A normal person can have a single horizontal palmar crease (simian crease), but his simian crease is just a trait he has, and has nothing to do with down syndrome. A normal person with a simian crease is not more likely to have a down syndrome baby.
