I am also confused about different types of CF. I just posted a (long) question about my father, who died of CF. He was not diagnosed until he was in his 30's, had 2 kids (I'm 25 and brother is 21), and lived to be 38 (he passed away in 1990) . Now I'm in shock because my 40-something uncle (dad's brother) has JUST been diagnosed as well. He also had kids, 3 of them (age 21, 18, 16). I don't know anything about this rare form of CF, and have posted seeking answers. Please check out my post "Rare CF, without male sterility... need info". It's here in the Families Forum. I'm terrified that this means my brother and I could be very susceptible to CF also(sp?). My father never had clubbed fingers, but he had all of the other symptoms, such as being tired, infections (he had a piece of his lung removed at one time), not being able to keep his weight up, coughing, and later having to use portable oxygen at all times. Does anyone know anything about this CF that comes later in life?pyriah@comcast.net I'm going home but I will be back in 2 weeks. Thanks everyone so much.
