| No Downs Syndrome is NOT something that runs in families. I spoke with a genetic councilor a week ago because the genetic testing my hubby said. This is something along the lines she said.
The cause of Down syndrome is a genetic problem related to chromosome 21. While Down syndrome is genetic in that it involves an extra chromosome 21, it is not usually hereditary in the conventional sense. That is, Down syndrome is not inherited; it does not "run in families." Down syndrome is usually the result of a random event that occurs during the formation of reproductive cells (eggs and sperm). |
