I think mastocytosis is caused by the a KIT mutation. It's fairly easy to differentiate from ET, which is usually caused by JAK2 or CALR, mutation.

Thank you for your reply. I do have the JAK2 gene mutation and both my PCP and hematologist/oncologist have only mentioned ET as my diagnosis. Except for the JAK2 mutation and high platelet counts, my other tests have all been normal and I have no outward symptoms.

Unless things start to go poorly, I'm trusting my doctors' diagnosis at this point. Your post is reassuring and I appreciate the info you are sharing.
