Here you can see if Pallister Hall Syndrome can be hereditary. Do you have any genetic components? Does any member of your family have Pallister Hall Syndrome or may be more predisposed to developing the condition?
In most cases, yes. Pallister-Hall Syndrome is a mutation of the GLI3 gene that is commonly passed down from parent to child. However, it is possible for the gene to mutate on its own, although this is very rare.
