Allie, your knowledge is wonderful. Neither of our families had a history of CF as far as we knew before our girls. My husbands family had done some searching for a niece that was born with a skin condition (she wasn't supposed to live to age 5, she is now in her 30's & married) that they (physicians) decided was genetic. We know that his father's side is French, his mother was English from Liverpool. When you mentioned your thoughts that G542X was from southern Europe I immediately thought of my family. I am Mexican, with my paternal great-grandmother being full Spanish but we don't know where from and my fathers side of the family being traced to the Basque region of Spain. To a village on the edge of the Pyrennes near Pamplona. I have often wondered where the gene could have come from. In the beginning when Anna was diagnosed (at age 3) we were told it was a predominantly caucasion disease. No one else from my family has ever been tested to see if they are carriers, so we don't know which side it's on.
Thanks for your info.
