I learned a new phrase today “genetic counsellor”. Apparently, at least in Canada, such things exist. I have been recommended to have the HFE gene test to see if I have hereditary haemochromatosis (HH). This for completion. Back in 1994 I visited this high haemoglobin “space” and was bled regularly at St Thomas’. Retrospect suggests that I may have had an ongoing health condition which was missed back then.

They took an armful each time. 

This HFE mutation would provide a benign explanation for my raised haem and ferritin levels. My ferritin levels have been increasing with time over the last four years. I don’t really have many of the symptoms associated with the genetic disease. It is linked with the less benign polycythaemia. Which would require a wider more substantive gene panel test, so-called molecular oncology. The authorisation for this testing is probably reserved for specialists. Iron overload is not without consequences. It can “cause” cancer or be correlated with it. Medical literature often blurs correlation with cause.

The problem with all this new-fangled gene testing is that it can open a can of worms

Needless to say, the genetics are complex.

I would be a mutant of sorts…

The next stages are Iron MRI and/or liver biopsy. The latter does not sound like much fun!!

Liver disease is possible maybe even likely, but I am largely asymptomatic. My enzyme work was ok.

The next stage of inquiry would be to look for myeloproliferative neoplasms which are rare, not lottery winning rare, but rare enough. Search of JAK 2 and other related things starts increasing the price. JAK 2 can mutate.

—————

“Mutations in JAK2 have been implicated in polycythemia vera, essential thrombocythemia, and myelofibrosis as well as other myeloproliferative disorders. This mutation (V617F), a change of valine to phenylalanine at the 617 position, appears to render hematopoietic cells more sensitive to growth factors such as erythropoietin and thrombopoietin, because the receptors for these growth factors require JAK2 for signal transduction. JAK2 mutation, when demonstrable, is one of the methods of diagnosing polycythemia vera.”

The thing is looking closely at most people my age the chances are that you will find something which has gone wrong.

The French sites suggest that some kind of follow up is warranted because of my Iron status.

Not sure what if anything the GP will recommend….

The osteoporosis situation seems simpler to treat with some pills, supplements and vitamins. But could have an Iron cause.

Given that the haemoglobin situation has been ongoing for, perhaps, thirty years it seems unlikely that any new unpleasant things have suddenly taken hold. But the ferritin level has doubled since 2021.

There is part of me that thinks that I just let this all drop…The osteoporosis might have enabled the fracture of my femoral neck six years ago. I have perhaps been living with it since. Simple answer is to not fall over.

A few more pills is no big deal however…

hereditary haemochromatosis – regularly being bled.

Not HH – Iron MRI / Liver biopsy —

Liver disease – it depends on what – treatments in absence of virus are usually diet and no booze.

Something fancy and esoteric – myeloproliferative neoplasms – massive complex can of worms

The French sites suggest that some kind of follow up is warranted because of my Iron status.

What is inside the can…?
