Guest guest Posted May 7, 2005 Report Share Posted May 7, 2005 After a lot of delays, today I got my first blood test result, for mitochondrial mutations. Considering that only 15% of people with Multiple Symmetrical Lipomatosis (MSL aka Madelungs) have any identified mutation at all, and that many such mutations are only identified by muscle biopsy, I guess I'm fortunate that mine was found by blood test alone. The famously " infallible " Athena Diagnostics tested 3 month old blood (how stored???) collected in tube types appropriate for a different (erroneously ordered) test, thereby violating their own protocols in two ways. According to them, I unequivocably have an mtDNA mutation at location " tRNA Lys A8344G " , which is the most common (80%) of the four mutations associated with MERRF. To my understanding and research, this mutation, because it was found in blood, could not have arisen spontaneously in me, and furthermore must have come from my mother. She died when I was five, reportedly of cancer (lymphoma). I doubt that ther six-year illness was completely misdiagnosed, but she apparently either harbored MERRF or was symptomatic but undiagnosed (not surprisingly, of course, in the early 1950's). She had only one child (me, a male) and no sisters (one of her brothers was quite healthy until rather old, but I don't know about the other). My two kids (one boy and one girl) cannot inherit this, and thus this local familial " strain " has died out. My maternal grandmother was spry in her 80's, so I doubt she was symptomatic, but her sisters may have had children and any of her siblings may have had MERRF, no way to know now. QUESTIONS: Any opinions on the above, i.e. have I understood maternal inheritance correctly? And what about the spontaneity? Also, any views on whether I should insist on a re-test? I expect this result will help with my disability application, that's now in its last round of appeal. I'm oddly buoyed, for that reason, but also troubled because now I can't hope that all my symptoms are just the result of something else that's easily cured. Ha, as if I really had any hope of that. :-) Nonetheless, this long ongoing journey has created in me a certain heightened awareness, about a lot of related important issues of life. And I suspect most all of you well understand what I mean. Sort of like a bit of " early " (age 55) wisdom, or at least, perspective, with a lot more compassion and understanding of suffering in all its many forms. Steve D.

Guest guest Posted May 7, 2005 Report Share Posted May 7, 2005 Steve I am glad you are finally getting the answers you are searching for and hope it really helps with the disability appel. I know what you mean about the joy and sadness that you feel. I think most of us go through that. I understand mtDNA transmission as you do. Good luck with the disability and give yourself time to absorb and deal with the diagnosis. laurie > After a lot of delays, today I got my first blood test result, for > mitochondrial mutations.

Guest guest Posted May 7, 2005 Report Share Posted May 7, 2005 Steve, Aha. So now you have an " address " to send your complaints. That's the way I always think of my mutation..location, location, location. I do hope this diagnosis aids your disability application. It certainly should. Labels are very helpful in such situations, even if they have mixed emotional implications for us patients. It should also help you get better medical care i.e. a doctor who pays attention. One can hope anyway. Even though the screening was done on mtDNA from " old " blood, I would think that would not necessarily invalidate the results, since mtDNA does not deteriorate in that length of time---at least that is what I understand. DNA is pretty hardy. I don't know what of kind of track record Athena has on mtDNA analysis, but identifying a known mutation should be straightforward. Hard to see how they could mess that one up. You're absolutely right about personal illness/suffering and how it raises our awareness of suffering in general. Too bad compassion has to be so hard won, but that's the only way most of us learn it, I'm afraid. Whenever I meet a very compassionate person, I always wonder what hard things have happened in their life.
