Here's a website that allows you to input your mutation and it will give you statistics regarding that particular mutation:

I hope that helps answer any questions you have.

You may actually be part of the data base; I think most of us are.
At some point your CF Center probably gave you a form to sign which allowed them to share some of your data anonymously (without using you name) with other organizations. That is where the genetic data base complied at CFTR2.org comes from.
