An individual with Down syndrome has one extra chromosome beyond 2N. Down syndrome is designated trisomy 21 or 47,XX+21.
down syndrome
There's many different genetic disorders such as: Down Syndrom Canavan Disease Muenke Syndrome Bloom Syndrome etc
Additional chromosome
No, there are not. Someone might, but not normally.
Nothing really leads to Down Syndrome, it is just an extra chromosome in the 21st pair. (otherwise known as Trisomy 21)
is down syndrome acquired genetic disease

The genetic developmental defect is spelled "Down Syndrome" or sometimes "Down's Syndrome."
No, Down's syndrome is only a human genetic disorder. Those with the disorder have an extra chromosome. Raccoons do not get this particular genetic disorder.
Having a sibling with Down syndrome does not directly increase the chances of giving birth to a child with Down syndrome. The risk is influenced by maternal age, not family history. If both parents are carriers of the genetic translocation for Down syndrome, the risk may be higher.
A karyotype of an individual's white blood cells can be used to diagnose chromosomal abnormalities such as Down syndrome, Turner syndrome, and Klinefelter syndrome. It can also detect genetic disorders caused by aneuploidy or large structural chromosomal changes.
Two genetic disorders are Turner's syndrome and cystic fibrosis.
Angelman syndrome is a genetic disorder, as is Down syndrome. But they are not the same. Angelman Syndrome involves a deletion of Chromosome 15, whereas people with Down syndrome have an extra copy of Chromosome 21.
Down syndrome is a genetic disorder, a person with this disorder has it for life, it does not go away.
Additional chromosome
No, because people with Down syndrome can't have children.
