Fecal Body Odor Reference Table

I will use this post as my 'quick reference table' of my opinion on what cause what seems to be the main complaint on the forums, which is termed as 'Fecal Body Odor'. I will keep updating this post.

Note, others don't agree with me. My own view is that since I do not think the spectrum of systemic body odor is currently defined, any opinion can't be proven/disproven yet. Think of it as understanding the universe.


my opinion
Fecal Body Odorcaused by the sulfides and amines which are FMO3 'substrates' 
FMO3an enzyme that oxidizes or reduces many sulfides and amines
TMAU ?means only trimethylamine causes the smell. But I am sceptical those with FMO3 weakness only smell of TMA
How did TMAU diagnosis come about ?In 1970 some consultants in Denver were told a patient smelt of fish sometimes and tested them only for TMA. Since then no-one has tested for other volatiles

FMO3 DNA testing
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
