No real advice... I don't know anything about that mutation...but I'm glad to see he is now going to move forward with testing for everyone....what about you? Is the doctor willing to test you as well?
I did find this much on the cf gene data base -- it doesn't tell you much, but at least it is listed... please post on the Ask Ambry post in the family section ...Steve should be able to tell you something

The above link has a link to published papers sighting that gene... looks like it is well known for an being either/both an Asian gene and/or a gene that typically causes CBAVD
