I find your post informative because I was diagnosed with MGUS in 2019. It’s a blood disorder that at present looks like it’s progressing into Non Hodgkin’s Lymphoma or worse Waldenstrom Macroglobulemia. A number of the issues with. JAK 2 are present in my bloodwork too. My B cells are mutated causing a drop in my red blood cells and platelets too. I’ve been anemic for over 3 years, longer than when they found I had MGUS. In researching JAK 2, I realized that the 5 blood clots between November 2021 and March 2022 may be triggered by undetected JAK 2. The first clot was the worst, it ended up in my right lung as a very serious Pulmonary Embolism. Number 3 blood clot tried to block my stent in the left atrial chamber and almost killed me. I have bloodwork scheduled for November, think I ask my Oncologist to add a JAK 2 test as well besides my cancer screening. Thanks for giving information I can and will use. Becky1024
