ALLELE BURDEN FREQUENCIES IN MPNS IN AUSTRALIA?

Post by MPN-MATE Admin »

Evening all... :D

I trust all are keeping Safe & Well, during what really are extraordinary times / events globally, through the advent of CV–19...

Shortly, I will be Posting about another attempt at a Fundraiser (FR), however, more about that later...

Today, I would like to ask any one out there, if they have ever heard, or know of anyone here in Oz, who has had a Test performed to discover their 'Driver' mutation's 'ALLELE BURDEN'?

One of our MATES members has recently asked me about this, and I am reaching out through a few avenues at the present. However, if any of you are know or are aware of someone in Australia, who performs these Tests, please do respond and let me know at your earliest convenience...

Best wishes & thank you... 8-)

No sorry I don’t know but will be very interested. This is something I keep meaning to bring up with my haem. Merry x

UPDATE COMING...
Afternoon everyone,

The following is an UPDATE to my seeking answers about MPN Patients being enabled to obtain and order "Allele Burden Frequency (ABF)" Testing for all MPN Driver mutations.

Allan, (one of our MATES members), started me off to discover these responses, and hopefully soon, we here in Australia will also be able to obtain these results, which can often reveal some prognostic values concerning having an MPN.

To date, in Australia, one can obtain a Test for the JAK2 'Driver' mutation, which is available presently at the Royal Prince Alfred, (where I believe the Testing can be - Bulk-Billed or a $75.00 Rebate is available via Medicare.

Further, I have been reliably informed through the Peter MAC CAncer Foundation, that most Australian states at least have one hospital w/ a molecular cytogenics department, who should also be equipped to provide such technical requests.

However, if an MPN Patient in Australia has one of the other 'Driver' mutations, I.e. CALR or MPL

The ONLY way at present to gain the equivalent information for ABF is by requesting a 'Next Generation Sequence (NGS)' gene panel, which is somewhat more expensive at circa $500.00

It is this writer's understanding that the writing below alludes to seeking greater Equity for all MPN patients, irrespective of which 'Driver' mutation they may have.

As I may have mentioned previously, knowing what a patient's ABF is can be a valuable prognostic tool, and in many cases might also provide cause for the removal of some anxiety, where MPN patients are generally concerned. There are many instances where people who might have been diagnosed w/ either ET or PV become most anxious and wondering what longevity they might now have. However, if there medical teams can show them that their particular MPN is mainly indolent then perhaps they might be able to rest a tad more easily, in my view...

Please everyone, do encourage your medical teams here in Australia, to add to the comments section, when it soon becomes available for the 'Expansion of Genetic Testing for MPNs'

Thank you, stay safe & well...

Steven


1532 - Expansion of genetic testing for myeloproliferative neoplasms under MBS item 73325

Page last updated: 21 September 2020

Application Detail:

Description of Medical Service

Molecular testing for the diagnosis of polycythaemia vera (PV), essential thrombocythaemia (ET) and primary myelofibrosis (PMF) can establish the presence or absence of specific mutations known to occur in patients with these disorders. MBS item 73325 currently provides for Janus kinase (JAK2) and myeloproliferative leukaemia (MPL) gene testing in patients with PV or ET. The proposed medical service being requested is the expansion of MBS item 73325 to allow testing for calreticulin (CALR) mutations in patients with PV or ET, and testing for JAK2, MPL and CALR genes in patients with primary myelofibrosis (PMF).

Description of Medical Condition

Myeloproliferative neoplasms (MPNs) are a group of disorders in which bone marrow stem cells grow and reproduce abnormally. PV, ET and PMF are MPN's.

Thanks for spending so much time in looking into this, Steve.
It's good to hear that allele burden testing is available in Australia, albeit with a sizable out of pocket expense for those of us who are JAK2 negative. Hopefully the latest application to MSAC to make it more affordable will meet with success.
Do you know when and how the application will be made available for comment?
Cheers
Allan

Evening again Allan... :D

My current understanding is simply to keep one's ear to the ground, and check back to the MSAC website from time to time, and as updates become further available etc...

It would be quite a coup if the NGS testing of CALR & MPL becomes as affordable, (via Medicare), as the current JAK2 ABF, currently performed at the RPA and hopefully soon by quite a few others...

At least we seem to be making some forward progress for a change... :D

Best regards

Hi Steve - this is an interesting topic and i have ABF on my list to discuss with Cecily Forsyth when I see her on the 12.11.20. I will keep you posted.

Hey Mark... :-)

(My most Profuse apologies Mark... I believe that this happened simply because I had just been chatting w/ Allan, & mistakenly thought this was his Post - Sorry again... ;-)


Yes, I actually believe that there is substantially more to completely understanding this ABF Topic...

By the way, I did write to Dr Cecily Forsyth, who did kindly respond just recently, and I have since replied to her again... She may not reply further, as she is a very busy individual, and I am grateful that she actually responded at all... 8-)

She had some very interesting thoughts, and also provided me w/ a Paper by a Japanese academic, (scientist?), I cannot recall just at the present which, possibly both... :-)) Link below for your interest:

https://doi.org/10.1182/blood-2013-07-515676

In any event, it was more focused on measuring ABFs after undergoing an ASCT, (as no doubt Cecily will allude to in due course).

However, I also continued to cross-reference that article w/ quite a few others, and sadly... the dates are a tad older. In more than a few cases they were not aware of CALR at all at the time of their composing etc.

One might argue that really doesn't matter anyways, because ALL Three (3) known mutations act upon the JAK-STAT Pathway, and that is generally seen as the more crucial import...

However, and again, if it can be used to aid knowledge in the success or otherwise of Post ASCT, then why not as a "Benchmark" upon diagnosis?

They are my thoughts, for whatever they might be worth...

Best of luck and I hope your consult goes very well, I am sure it will Allan.

Please do let me know...

Best

Steve
