MEBO Metabolic Malodor Survey (international) for Dr Hazen click here
click to Read more/less

survey for ANYONE who identifies with METABOLIC MALODOR

begun : Oct20
end : no ending for now

Regular readers will know that Dr Stan Hazen et al at Cleveland Clinic are developing a TMA-blocker pill, as they proposed in a 2011 paper that TMAO is a factor in CVD. Recently Dr Hazen and colleagues contacted MEBO as they have always thought they could also help with TMAU. This survey is to give them an idea of the 'state of the community'. It is a "version 1". They may not even look (though they have access permission), but it could be useful to give them an overview of the community

MEBO had a zoom call with Dr Hazen and his team in October. Another zoom call is planned when they have time

This is a GOOGLE FORMS survey

could PTC124 help with primary trimethylaminuria due to a nonsense mutation ?

As mentioned in the post about the Australian trimethylaminuria research proposal, one of the two proposed experimental treatments for trimethylaminuria is using the drug PTC124 (to be marketed as Ataluren), in cases where the person has primary trimethylaminuria due to a nonsense mutation of the FMO3 enzyme. Nonsense mutations instruct the developing protein (in this case FMO3 protein) to prematurely stop, and in effect abort the development. Nonsense mutations are also known as 'stop codons'. PCT124 (along with some antibiotics which have already been shown to have the same effect, but have side effects) has been claimed to overrule If it was of benefit, it would only be expected to work in a trimethylaminuria sufferer who had primary trimethylaminuria due to a nonsense mutationany nonsense mutation premature stop, and so allow whatever protein that was developing (in trimethylaminuria ; FMO3 enzyme) to fully develop. It must be presumed they expect more protein to develop only to a certain degree (i.e. they don't expect function to become 100%, but perhaps increase the level by 5% or more).

At the moment PTC124 is not available, except for research purposes (so if anyone knew any trimethylaminuria experts, they would be able to use it in research). It is being used in trials for muscular dystrophy and soon in cystic fibrosis. It seems it could get FDA approval in 2010 or shortly thereafter, assuming all goes well in the final trials. In mice and in a small group of human trialists, there seems to be no side effects except apart from upset stomach in a few. The toxicology data looks very promising. It is taken orally as a powder, for instance in water or fruit juice. If it was of benefit, it would only be expected to work in a trimethylaminuria sufferer who had primary trimethylaminuria due to a nonsense mutation. Offhand, it's not known how many have this type of mutation in FMO3. In some other illnesses (it's expected it could work in all genetic disorders due to nonsense mutations), the % due to a nonsense mutation can be anything from 5% to 70%. Perhaps someone could find out how many FMO3 mutations are regarded as being due to nonsense mutations.

At the moment the final phase of the muscular dystrophy trial is underway, and now Dr Christodoulou proposes to trial it for trimethylaminuria too, as other researchers are free to do so as well. It's remarkable that a drug may soon be available that can improve enzyme function in genetic cases.

More posts will follow about PCT124. in the meantime, here are some links about it:
