Guest guest Posted August 27, 2006 Report Share Posted August 27, 2006 Hi Rich, Do Sciona tests make sense after learning more about Yasko? These were in heart panel. Well it looks site doesn't sell separate panels now. Kathy Sciona tests for MTHFR A1298C (I'm A/C) and CBS C699T (CC). Is this one of the right CBS tests? Does this combination mean there are ammonia issues? would BH4 be good for my case? Where do you get BH4? Has anyone tried it? I don't eat high amounts of protein. Have been having gas from spirulina, no problems other vegs. On my old amino acid test phenanyl... and tyrosine both look mid range, tyrosine a little lower. Thank you. Sorry I am very behind on posts. Kathy .......We may be able to infer to some degree what the genetic variations are in a person without having to characterize them, at least in a rough way. For example, if we could just separate those who have CBS upregulations or MTHFR A1298C SNPs from the rest, without expensive testing, that would help a lot. I'm actually working along those lines, a. It may turn out to be possible. Rich Joanee and Rich >Considering next the methylation-cycle-related enzymes, we don't have the complete results on these yet, but we do know that you were born with an MTHFR A1298C (+/+). This means that at a minimum, you would have had a tendency toward low levels of _tetrahydrobiopterin _ (BH4), which would have hindered your ability to synthesize serotonin and dopamine. /(I found this information on Yasko's DVD, she mentions that persons with MTHFR A1298C (+/+) need to supplement BH4. Dr. Gordon wants to wait for Yasko's test results to confirm this as BH4 is very expensive. This also brings up the question of just how much supplementation to do at this point in time. Yasko has a very long list of " step 1 " supplements and strongly advises patients to spend sufficient time on step one prior to adding all the elements of " step 2 " which is methylation. Of course, she is used to treating children. I have already incorporated many of the " step 2 and 3 " supplements over the course of time, like glutathione and I am not sure how to proceed. I will attach a list of what I am taking and would apprecriate imput from you and the group on what to modify.) > > ***I will of course defer to Dr. Yasko's advice on this, but it > would seem to me that going ahead with BH4 would be a good idea.

Guest guest Posted August 28, 2006 Report Share Posted August 28, 2006 Hi, Kathy. Well, those are two of the SNPs that are on the Yasko panel, so these results will tell us a little, but not the whole story. You are heterozygous for MTHFR A1298C. Dr. Yasko would say that you would have a tendency to be somewhat low in BH4. Since you are female, if you also have aluminum toxicity, that would tend to block the other enzyme for making BH4, and then you would be even lower in it. Your phenylalanine to tyrosine ratio doesn't sound very high, and that would say that you don't have a big shortage of BH4. BH4 might help you to some degree, but it doesn't sound like a major problem for you. I understand it is quite expensive, and must come from Japan or Switzerland. I suggest that you check on autismanswer.com about sources and experience with it.I'll put my list of questions below, and maybe we can make some other guesses based on your responses. You don't have the main CBS SNP that Dr. Yasko looks at (CBS C699T). We don't know if you have one of the others, such as the CBS C1080T, which she believes is also an upregulator, so at this point I can't say if you would have a tendency toward excess ammonia or not. I think that's about all I can say from these results. Rich > > > > Hi Rich, Do Sciona tests make sense after learning more about Yasko?

Guest guest Posted August 29, 2006 Report Share Posted August 29, 2006 Hi Rich and Kathy, I just wanted to mention something Dr. Amy wrote on the autismanswer forum wrt phenylalanine. " For instance Hippuric being high on an OAT test could indicate a bacterial issue or elevated phenylalanine as a result of decreased BH4, the excess phenylalanine can lead to higher levels of hippuric acid. " So perhaps this means that one could have normal phenylalanine since it is being converted to hippuric acid. This article http://www.pnas.org/cgi/content/full/96/5/1811 says: " Adding PAL to the diet could be one of these ways. PAL degrades phenylalanine to ammonia and transcinnamic acid. The latter is a harmless product that is degraded further to benzoic acid, which in turn is converted to rapidly excreted hippuric acid " Do you know what your hippuric acid is Kathy ? Re: MTHFR and CBS and BH4 Hi, Kathy. Well, those are two of the SNPs that are on the Yasko panel, so these results will tell us a little, but not the whole story. You are heterozygous for MTHFR A1298C. Dr. Yasko would say that you would have a tendency to be somewhat low in BH4.

Guest guest Posted August 31, 2006 Report Share Posted August 31, 2006 Thanks for answering Rich and , I thought I had high aluminum, but it's not one of my high ones. On 24 hour metals tests my creatinine is 26 of range of 35-225 and on regular tests it's right at the low end. I don't have a hippuric acid test. Is OAT an organic acid test? I thought that was similar to Great Smokies cellular energy but doesn't mention that acid. Anyway people could check heavy metals tests for creatinine levels.
