What are the causes of people to be born with down syndrome?

What are the causes of people to be born with down syndrome?

Extra chromosome 21: A woman's chances of giving birth to a child with down syndrome increase with age because older eggs have a greater risk of improper chromosome division. By age 35, a woman's risk of conceiving a child with down syndrome is 1 in 400. By age 45, the risk is 1 in 35. However, most children with down syndrome are actually born to women under age 35 because younger women have far more babies. ...Read more

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. ...Read more

Chromosome influence: The size and shape of the skull and facial features of down syndrome patients is heavily influenced by the effect of the extra chromosome present in every cell of the body.The same goes for eyes, hands, feet, all of which require a lot of decoding during formation to produce the structures.Other chromosome defects produce some common features to those born with a specified extra chromosome. ...Read more

The typical ds diagnosis can be ruled out, but the test does not exclude other problems that can give an infant an unusual look, or might be a problem in the future. The pcp can monitor the situation over time & look for other issues if there appears to be a need for additional study. ...Read more

What causes down syndrome?

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
