I was diagnosed with essential thrombocythemia in 2020. Although my platelets have been elevated since I can remember, and my father passed away due to what seems to have been high-risk myelofibrosis at age 62, it took a while to convince my hematologists to test whether the mutation I have is inherited. The results are in and my mutation, MPL R102C, is germline, it is inherited. So now my diagnosis was changed from essential thrombocythemia to hereditary thrombocytosis.
I received the whole "as there is no clone, HT strictly does not enter into the chronic blood cancer category," and I held my ground and mentioned that the mutation I have has the same effects on my body as any sporadic mutation that results in ET would have: increased number of platelets, dysfunctional platelets, risk for clotting and bleeding, risk for transformation in MF, etc. So while this diagnosis means that, sadly, there is no treatment for me other than aspirin, the effects HT has are the same as ET. And that I do not want to fall through the chairs because at the moment there is no treatment for HT and that not much is known about the mutation I have.
My hematologist is OK and well informed, so I am lucky in that way. I just want to make sure I push as much as I can for better research and better knowledge about hereditary thrombocytosis (HT).
