The problem is my brain can't understand genetics The four variants found are Exon 3 instead of Exon 7. And 3 are 'documented polymorphisms' whatever that means. The last one is not yet documented but is considered unlikely to matter due to its position 'outside the protein coding region' whatever that means.. I had made my mind up that I was not going back the the neuro without proof as he was so rude, and I am not sure that this is proof. It is just a curiousity but not re to CMS ?? I guess it would be rather interesting to get my second cousin tested and see if she carries the same 'variant' but I am still not sure if this is a wild goose chase or not. My symptoms are so mild now as the albuterol has worked so well. But 20% of people respond to placebo anyway ... so ??? I am not sure if I am delusional for looking at these results and seeing an oddity or not!
