Diagnosis- You can tell if your baby has a cleft palate if there is an opening on the roof of their mouth and/or lip.
There is no single known cause, rather there are multiple possible contributing factors. About %15 of cases are likely a side effect of some other birth defect, other cases are likely mutations. It's not known for sure if it can be inherited. It's possible that certain medications and/or harmful substances can contribute to this defect.
1 in 600 US babies are born with some sort of cleft.
