My wife is pregnant, and we have both tested as positive CF carriers. (Cystic Fibrosis).According to the March of Dimes, 1 in 31 people in the US are symptomless carriers of the CF gene, and the only way for a kid to actually get CF is if both parents are CF carriers. In that case, there's a 25% chance (1:2 x 1:2. Call your HS science teacher an apologize; that stuff about Mendel and peas DID turn out to be useful in your future life.) a child will show CF symptoms, and a 50% chance he'll be a symptomless carrier.
We are going to see a geneticist early next week, wondering what to expect. Kind of a downer as opposed to the lighthearted humor that attracted me to the weblog, Hoping for some insight from parents that might have gone through it, how they coped, etc.
[Diagnostic trivia: before the development of genetic testing, a baby with CF was usually diagnosed by a "Sweat Test"; CF causes extra-salty sweat. Now, though, pre-pregnancy/early pregnancy blood testing is recommended for both parents, and in-utero test are also available as early as 11 weeks [for CVS] and 16 weeks [for amnio], to help parents-to-be to get ready and educated.
Anyway, if anyone out there has CF, or has a child with CF, or is a carrier and can share experiences and/or resources you found useful, definitely chime in.
