Hi @pennyhedgecoth and welcome to the Blood Cancers & Disorders group. I'm glad you found us. It is such a challenge to be a caregiver at this time and not be able to accompany your husband to his appointments. I hope you are able to ask your questions through the portal.
I'm going to take a minute to spell out several of the acronyms, although I suspect most people in this group know they all, but just in case:
BMB = Bone marrow biopsy
MPN = Myeloproliferative neoplasms
PV = Polycythemia vera
HCT + hematocrit
From what I've read ASXL1 mutations often co-occur with JAK2 V617F. I'm tagging fellow members @mjpm2406@helen2209 and @stevehurlburt, who know more than I do and may be able to share their experiences.
Penny, what questions are you wanting to ask the oncologist?
