Guest guest Posted October 11, 2004 Report Share Posted October 11, 2004 I guess I'm not sure what you mean by " read " the muscle biopsy. I don't have " ragged red fibers " and my mitochondria don't look abnormal, yet I have a severe Complex I defect from lab testing of the fresh muscle biopsy. You might want to ask if they are doing " ox phos " (oxidative phosphorylation) chain testing on your muscle biopsy. I had a muscle biopsy with local, and they tried but failed a spinal tap right afterwards. Take care, RH > Dear RH, > Sorry for the delay in seeing this post.

Guest guest Posted October 11, 2004 Report Share Posted October 11, 2004 Dear RH, By using the word " read, " regarding my upcoming biopsy, I mean " interpret. " My first showed a vacuole, a ragged red fiber, and deficiencies in Complexes I, III and IV, and of citrate synthase. I presume that's what you meant by the ox phos cycle. At that time, in 1999, they could not nail a particular kind of mito, although Dr. Hirano said he thought I have a mito encephalomyopathy. Having just read Dr. Cohen's answers about mito on the Sept. MDA chat, I believe that he feels there are many more mito mutations than originally thought when he entered the field. It is my understanding that those of us here on the mito lists who have been dx'd with mito, have never been given a specific dx, like MELAS or MERFF or NARP, etc. With those who have, the specific dx seems to come only after a close relative has died of mito. When several of the men on these lists have been dx'd with mito in early middle age--and one has died--their mito profiles and progressions seem to me to be more similar than those dx'd in childhood, or for women dx'd. This is just my impression. I have a hunch that some mito is more gender-specific. Take care! S. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted October 11, 2004 Report Share Posted October 11, 2004 I had fresh muscle biopsy testing in 2002, and they identified a complete absence of Complex I activity. I'm not sure why they are repeating the test for you if they did find deficiencies in several complexes. Maybe looking for other issues, like fatty acid metabolism? I don't plan to have another muscle biopsy, and I think they even kept some of the muscle " just in case " they come up with some new testing. My diagnosis is " mitochondrial encephalomyopathy, MELAS-phenotype, unknown genotype " , which means my presentation is MELAS, but I don't have any of the few known MELAS genetic markers. I have a paternal uncle with very similar symptoms - his onset was age 70, I got sick at age 25. Interesting article on the subject of not knowing a specific defect: =============================================== A novel mitochondrial tRNAPhe mutation causes MERRF syndrome. Mancuso M; Filosto M; Mootha V K; Rocchi A; Pistolesi S; Murri L; DiMauro S; Siciliano G Department of Neurology, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA Neurology (2004 Jun 8), 62(11), 2119-21. Journal code: 0401060. ISSN:1526-632X. Journal; Article; (JOURNAL ARTICLE) written in English. PubMed ID 15184630 AN 2004284474 In-process for MEDLINE (Copyright 2004 U.S. National Library of Medicine on SciFinder ®) Abstract A woman with typical features of myoclonic epilepsy with ragged red fibers (MERRF) had a novel heteroplasmic mutation (G611A) in the mitochondrial DNA tRNA phenylalanine gene. The mutation was heteroplasmic (91%) in muscle but undetectable in accessible tissues from the patient and her maternal relatives. Single-fiber PCR analysis showed that the proportion of mutant genomes was higher in cytochrome c oxidase (COX)-negative ragged red fibers (RRFs) than in COX-positive non-RRFs. This report shows that typical MERRF syndrome is not always associated with tRNA lysine mutations. =============================================== I was told that whether or not I have MELAS exactly, I would be treated the same way, based on my symptoms and what the lab tests showed. The basic thought is: 1) Check out systems with problems (for me, eyes, muscles, digestive). 2) Get a baseline for systems without problems yet (for me, heart, ears) 3) Treat by going down the list of the " mito cocktail " . Starts with CoQ10, and there are about 15 on Dr. Shoffner's list. And, it does seem that men are worse affected than women, although it is proven that women are " stronger " than men when it comes to illness, probably to make sure people have kids. If we were just dealing with mtDNA, it would be easier to figure out the genetic distributions, but there are nDNA defects as well (mine is probably nDNA based on the family pattern). Maybe we just all have " lactate-pyruvate imbalance " LOL. Just heard a discussion on changing " impotence " to " erectile dysfunction " for marketing purposes, we need to get a better term to market mito.

Guest guest Posted October 11, 2004 Report Share Posted October 11, 2004 The names such as MELAS, etc. are only names for a cluster of symptoms. Unless a specific known mutation is found, it is just used for convenience. My opinion is that it is more important to know what isn't working properly instead of having a " name " for it. Even those with the same mutation or defect can have very different symptoms (even in the same family) laurie > From: BDS31@... > Reply-To: > Date: Mon, 11 Oct 2004 14:51:27 -0400 > To: > Subject: Re: Re: 2nd muscle bx: to be read at Columbia-Presbyterian, > NYC > > Dear RH, > By using the word " read, " regarding my upcoming biopsy, I mean > " interpret.

Guest guest Posted October 11, 2004 Report Share Posted October 11, 2004 I agree 100%, Laurie. First, it is important to know which metabolic pathways are impaired (and thus causing the symptoms) and then the next most useful piece of information is the specific mutation that is causing the impaired pathways. Unfortunately, mutation identification is rare for most mito patients right now. We will just have to wait until technology catches up, meaning more mutations are identified and mutation screening becomes less expensive and more available to more patients. I feel very fortunate to have the mutation for one of my defects identified, but I expect I'll be waiting a very long time for the mito transport defect mutation to be found, given the infancy of mito transport science.
