Prof Colin Dolphin post about potential TMAU therapies

Prof Colin Dolphin is an English academic who has had a long-term interest in FMO3 enzyme and TMAU. I believe he was one of the team who documented the FMO3 gene coding sequence in the late 1990's

Occasionally Dr Dolphin writes posts on the tmau.org.uk forum for TMAU people. Indeed he has been given his own thread there : Questions for Dr Dolphin

Recently he posted an in-depth post about potential therapies for TMAU and the obstacles.

Dr Dolphin's tmau.org.uk post about potential TMAU therapies : link

My non-expert interpretation of  the post :

The post suggests 3 potential TMAU therapies and their obstacles :

1. Using bacteria that can oxidize TMA in the gut to TMA-oxide
Obstacle : these bacteria tend to be aerobic (need oxygen) and do not tend to survive well in oxygen-deprived areas (such as the gut)

2. Genetically modifying gut-friendly bacteria with enzymes that oxidize TMA to TMA-oxide
This would seem more possible, but the TMA-oxide may be quickly 'reduced' back to TMA by other gut bacteria enzymes. So it would be a cycle of TMA-TMAO-back to TMA.

3. A drug that blocks the production of TMA from choline/carnitine etc.      
Again seems possible but may involve taking many drugs and not really practical ?

Dr Dolphin mentions a final idea where the aim would be to eliminate TMA-producing bacteria in the gut (?). He also mentions how he applied for a grant to check the gut flora of TMAU population against normal people but the application was unsuccessful.

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
