Is Down syndrome congenital or genetic?

Down syndrome, also called Down’s syndrome, trisomy 21, or (formerly) mongolism, congenital disorder caused by the presence in the human genome of extra genetic material from chromosome 21.

Can folic acid prevent Down syndrome?

Can two parents with Down syndrome have a normal baby?

Parents with one baby with regular trisomy 21 are usually told that the chance of having another baby with Down’s syndrome is 1 in 100. Very few families are known who have more than one child with Down’s syndrome, so the real chance is probably less than this.

Why parents that do not have Down syndrome can have a child with Down syndrome?

Is autism a genetic disorder?

Genetics. Several different genes appear to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome. For other children, genetic changes (mutations) may increase the risk of autism spectrum disorder.

How does Down syndrome impact the family?

The experience and knowledge gained by having a sibling with Down syndrome also seems to make children more accepting and appreciative of differences. They tend to be more aware of the difficulties others might be going through, and often surprise parents and others with their wisdom, insight and empathy.
