I have never heard of this dysfunction until you mentioned it. But looking on the net, I have found very little about it. I'm sorry. I know how frustrating that can be. My 8 yr old son has a very rare chromosome abnormality and to this day I can find very little about it on line. It's more or less a learn as you go process. I did find an article about your son's condition and I will share the link with you. I don't know how much help it will offer you. But as someone mentioned previously surgery is recommended to correct the problem. However, I am uncertain as to whether or not they will perform the procedure on a new born.

You may want to check with the pediatric gastrointestinal specialist at UVA. The doctors there are wonderful and have seen my son regarding feeding problems as well(he has dysphagia and due to constant aspiration had to have a feeding tube placed). They may be able to help you find the information you seek and refer you to a speicalist in your state. Thier number is 1-800-251-3627. If you do call just as for the Pediatric GI clinic. I wish you and your son the best.
