My daughter, age 26, has the same two mutations. I also do not know much. The R560T, I think, is pretty uncommon. My niece, age 33, was just diagnosed w/ mild CF. She has the R560T and T5 and only has sinus problems. My daughter was diagnosed at 3 months of age as a failure to thrive baby. The digestive problems were the first to surface. All in all, she is doing okay and works 3-4 days per week as an accountant. She's married and very active physically, going to the gym almost every day. My best to you and your child.Kerry
