Thank you for your response. Our son has no symptoms. The salt test is 59 and 60, the pancreas functional. Unfortunately Kalydeco in Slovakia is not yet approved. Well, we hope. Kalydeco would be very helpful. In what condition is your daughter's breathing? I hope your daughter will do it. Could we stay in touch (viber, mail or Facebook)? Finally, we found someone with the mutation d110h, we are very excited. Well thank you.
