If an older sibling has Down syndrome will a newborn baby also be born with syndrome?

Having a sibling with Down syndrome does not necessarily mean that a newborn baby will also have the condition. Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. It is a random occurrence and is not directly inherited from parents or siblings.

Therefore, the chances of a newborn baby having Down syndrome are not increased solely because an older sibling has the condition. The risk of having a child with Down syndrome is generally low and is influenced by various factors such as maternal age, family history, and specific genetic markers.

If you have concerns or questions regarding the possibility of Down syndrome in a newborn baby, it is essential to consult with a genetic counselor or healthcare professional who can provide accurate information and guidance based on your specific family circumstances and medical history.
