As I am recently diagnosed, reading the posts is quite an education. It will help with my first hematology appointment later this week. (Yes I am an American so for me it is hemo- not heamo-)
But... can someone tell me what JAK2+ means? My primary care physician told me I have the JAK2 gene. I have also read that here is a mutation of JAK2. Also that not all ET patients have JAK2. So my question is: Does JAK2+ mean the gene is present or does it mean the mutated gene is present?
