Thanks for the article. It was useful. It seems to me when discussions get moved, they are just buried in old discussions, so I'm not sure this will not get any replies other than that of the moderator. But, I appreciate the article you did send. It is very useful, and along with some other internet research, indicates that it is possible to test positive for the mutation without having overt disease. Given my consistently high WBC counts, I'm going to *guess* that the mutation has already had some effect, but will have to wait for a bone marrow biopsy to be certain. And, my allele burden is significantly above the cut off typically given for "mutation in healthy individuals" ...although my testing was done in purified granulocytes, while the articles report testing in whole blood, so I'm not certain if the numbers can be meaningfully compared. Ugh! I have just enough information to be worry over the holidays, without enough information to have any sort of a plan.
