Trimethylamine in humans : communicatory role ?



New paper on TMA in humans.
Seems to be a speculative paper looking at past papers to hypothesize that trimethylamine may have some sort of role in humans, possibly a communicatory role. Probably a negative role

Mitchell and Smith :
The paper is of special interest as the 2 authors have a long history in TMAU research, and could be called TMAU pioneers. Mitchell wrote a lot of early TMAU papers from the 1980's onwards, and Smith is a Professor (retired) who did research in the 90's. Neither of them has been involved in TMAU papers for maybe a decade.

My interp of the paper :
There seems to be no new research done. They have looked at past papers and seem to imply there may be a communicatory role for TMA humans, probably a negative role I guess (i.e. implies ill health).

They make a point of saying how TMA is detectable to the human nose at very low levels (at least, as recorded in 1 or 2 anecdotal papers). Probably one of the volatiles with a lowest detectable odor.

Overall it is a mildly interesting hypothesis but seems speculative and I don't feel it added anything new that might help TMAU people at the moment.

Update Aug 17 :
Genos is back with it's EXOME test

Note :
Exome/Genome testing may be better option than single gene testing.

See this post : link

Note : Genos Exome Testing.

Exome testing is almost the same price now as single gene testing. Also Genos is consumer friendly, which standard DNA labs are not.

So the blog offer to test solely for FMO3 is almost obsolete, and so no longer offered.


Does Genos fully sequence FMO3 gene ?

At the moment it is not clear, but hoped this will become clear over the next few months

Note : possible 'wild west' way of testing FMO3
Use an ancestry dna site and rummage through the raw data
