JAK2 Mutation - Effects and Questions

Posted by ettap @ettap, Mar 29, 2018

Have JAK2 mutation verified twice; one year apart and from different labs. As I understand, it may cause polycythemia vera, essential thrombocytosis, or leukemia. My hematologist has not provided any real info on this mutation so I've been researching via internet. I knew leukemia is cancer but was disappointed to find out today that the other 2 are blood cancers as well. I have been seeing a hematologist every 3 mos. about this since my 2nd blood clotting event in 09/2016. To date, all my blood factors have been in the normal range. Here are some of my questions: 1. Is it typical to verify this mutation well before it triggers one of these diseases? 2. I know early detection of cancer can be a real plus, but is there any research or experience that supports proactive steps that can be taken to deter the onset of any of these possibilities? 3. With polycythemia vera and essential thrombocytosis, is blood letting the primary treatment? If so, can the blood be donated? 4. Since none of my blood factors have ever been out of the normal range to date, no specific result of the JAK2 mutation has raised its ugly head. Is this normal? I'm not typically a worrier. In fact, I do really well with things like this once I know what I am dealing with. Information becomes my sword which allows me to take worry and nip it in the bud.

Since you mentioned ET and the VA in one sentence may I ask if you were ever stationed at Camp LeJeune. NC? If yes, we can have a conversation at the contaminated water at that military base and the fact that the toxins in that water cause MPN and MDS blood cancers as well as other cancers.

I’ve heard of Camp Lejeune and how ET and other blood cancers have been traced to it. Has the military acknowledged this and are they compensating individuals ? On the MPNRF site, it also mentioned electrical wiring as being suspect in the cause of ET and other MPN’s. Wonder how many other electricians have MPN.

I was told i had Central Vestibular Vertigo by the best ENT in South Carolina, I got a look at my CBC and told my Doctor (PCP) I have some type of cancer and it turned out to be ET, I'm a master electrician, not a Doctor. That's the VA for you.

We may be on to something. I have blamed it on my COPD, however I don't need daytime oxygen. But I sound like both of you and go to bed by 6:00, just to rest. It is nice to know that it could be not in our head. I hate being lazy. lol

After reading that so many JAK2 people experience being weak or tired, and have balance issues, now I wonder if I can attribute my similar symptoms to the disorder. I tell people that my balance issue can be described as having been on a cheap drunk without having the pleasure. And I now tire easily. So now I’ll discuss this with my hematologist next week.

Hi Barbie......I have jak2.....myeloproliferative neoplasm, I believe it is similar to pv. Chronic fatigue most of the time, poor balance and occasional nausea. When I feel weak I try to rest often and for at least two hours at a time. I usually go to bed by 6 o'clock just to relax and watch tv

I'm happy to share my experience. #1. No, do not need to give blood. The Hydrea is toxic enough to kill the excess platelets. #2. I have experimented over the years to cut back a little from the prescribed dosage simply to minimize the amount of toxicity I'm consuming. My Docs have not liked this kind of fooling around with the dosage. So I've been steady at 6 days a week, no Sundays for about a year. No side effects from the Hydrea after the initial first month twenty years ago. #3. I still have no symptoms of this strange blood disorder called ET, regardless what my count is on any given day. I go every 3 months for a cbc. It puzzles me that at 72, I still feel the same with a count of 480 as I did at age 40 when I was diagnosed with a count of 800. #4. My two Docs (first one retired) have dangled the ultimate fear over me since the diagnosis, but so far my ET has not morphed into leukemia. Having no symptoms and in disbelief, I went to the Scottsdale Mayo Clinic for a second opinion at some point in the 1990s. Same diagnosis. Very disappointing because I was really convinced that nothing was wrong with me. Thanks for sharing the NIH info. I always like to run across updated information on PV,ET, and other blood disorders. You may never progress to anything more advanced. Best wishes.

My JAK2 Mutation was discovered 11 years ago, quite by accident. I never had any symptoms. (My hematologist told me that for many, the only symptom is death, by a blood split in the brain, heart, or lung!). My original platelet count was close to a million! I’ve been taking Hydrea daily ever since, with no side effects from the drug. However, over the last couple years, my count has fluctuated between 450 to 800. My dosage is adjusted and rechecked again in 4-6 weeks. It’s possible the Hydrea might be losing its effectiveness. I worry that another drug cost or copay might be astronomical! If only a cure could be found. I’m 76 now, and other than arthritis, am in very good health.

Even though you take hydrea six days, do you still
have symptoms of PV? If so, what are your symptoms and how do you handle them?

I am Jak2 and this was diagnosed after 2 mild strokes in which I experienced numbness in my left hand, inside my left cheek and tingling of my left foot. Both strokes occurred in the sa.e week. My platelet count was very high and my BP shot up well over 250. I am 75 and otherwise very healthy. I am on aspirin, hydrea, and bp meds and doing fine but am extremely tired most of the time. How do you all handle the fatique?

I am tired some in the morning but otherwise once I get going I’m ok. I wonder if it is your BP meds making you tired? How’s your diet? Do you take any supplements?

Is anyone in this group from Maine???

Hi Barbie 75....I also have jak2 and take 500mg Hyderabad six days a week. I still have extreme fatigue so I just take the time to put my feet up and rest my body or get right into bed. This seems to work. Mornings are the best part of my day but by noon I feel weak. Good luck
