What causes these conditions?

Most of the time these are genetic conditions. Usually babies are born with them when they inherit a gene that has a change in it from both parents. This change stops the gene from working properly. These conditions are not caused by anything that happened during pregnancy. There may be no signs of these conditions at birth. It’s important to remember that many treatable conditions can’t be seen by looking at your baby.

What if testing shows m​y baby has one of these conditions?

The specialists will work with you to suggest treatment and make a care plan for your baby if tests show that your baby has one of these conditions. Your healthcare team is there to provide the best care and support possible to you and your baby.
