My daughter has Nf plexiform type. she is being married in three months and I am so worried. she wants children and i am concerned that the disorder will exaserbate in her body. the fetus will be able to be checked for NF and she can decide whether ti terminate the pregnancy but it is she that I so worry about. she is my fourth child and NF is a mutation and not found in our family tree. Please help with information. thank you
