Re: R117H mutation?
DS is double delta f508, so I can't help you with the mutation, other than I know of people with children with that mutation and another, who seem to have milder symptoms.
I would be concerned with the bright bowel on the u/s. I would hope that they are monitoring you, continuing to monitor you and that you have access to a high level NICU when your child is born, should he/she need surgery right away. DS was born with a bowel obstruction caused by meconium illeus -- apparently it didn't show up on the u/s. He was lifeflighted the next day to a hospital several hours away for emergency surgery.
I do know of people who have opted to have their unborn child tested for CF before birth, but I believe there are risks involved. Otherwise, you could probably have your husband tested by ambry or quest for a more extensive panel and/or have your newborn tested right away.
Sorry I'm not much help.
