Question 1

what is down syndrome?

Accepted Answer

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.

Question 2

what causes down syndrome?

Accepted Answer

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?

Question 3

is down syndrome inherited?

Accepted Answer

Down Syndrome: Down syndrome is a genetic condition caused by an extra copy of a specific chromosome. Not sure what you mean by inherited.

Question 4

how is down syndrome treated?

Accepted Answer

Medical/education: Children with Downs Syndrome have special medical and educational needs that should be determined in each individual.  Doctors and Psychologists or educational specialists can determine what the needs are and how best to meet them.

Question 5

why is my baby down syndrome?

Accepted Answer

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.In ds the pair of moms 21c +dad's 21 creates a baby with the three 21c in all tissues.This extra material confuses the creation of body parts causing ds..Various prenatal tests can pick up signs early on.

Question 6

why does down syndrome happen?

Accepted Answer

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.

Question 7

how can you inherit down syndrome?

Accepted Answer

Yes: A woman with Down syndrome (trisomy 21) may be able to get pregnant, but men with Down syndrome are almost always sterile, due to problems with sperm production.  That means about half of the babies born to women with Down syndrome will inherit an extra chromosome #21 and be Down syndrome babies.  Said another way, if you inherited down syndrome, your mother must have had down syndrome.

Question 8

how do you diagnose down syndrome?

Accepted Answer

Karyoytype.: Dna analysis or karyotype is diagnostic of Down syndrome both prenatally and postnatally.

Question 9

down syndrome is autosomal dominat?

Accepted Answer

No: No. It is chromosomal. Down syndrome is not usually passed from one generation to the next. So it is not dominant or recessive.

Question 10

how does a person get down syndrome?

Accepted Answer

Dividing Chromasomes: We all have 22 pairs of regular chromosomes (chms) plus an xx or xy of the sex chms. The pairs split during egg or sperm formation so each has 22 chms + an x or y.  If the 21 chromosome doesn't split right & brings a pair to the egg(or sperm) the fertilized egg will have an extra 21 so the infant will have 47 total. All subsequent cells have 47, giving rise to a ds kid.
