Sitting here in tears and need advice
The w1282x is the most common CF gene in Israel, and it's common in general among the Jewish population. Allie's Ry had a DF508 and a w1282x. Since you're looking for info, I will tell you that w1282x is a Class I mutation. But as Amy said, this really means next to nothing. Don't worry about it.
Besides, this means you're cooler. If I had a double DF508 I'd have been bummed about being normal. I'm lucky enough to have a weirdass splice mutation 1898+1G>A (also a Class I, if that makes you feel any better).
This is something I found online. <i>Class I mutations, such as W1282X, produce an early stop codon, unstable mRNA, and absence of CFTR protein.</i> So there you go. The w1282x mutation produces an early stop codon and the writing of the gene stops before it's supposed to. It's also called a nonsense mutation.

This is more specific information about the mutation itself:
