Denver TMAU Test Lab survey click here

USA survey for anyone who wants to improve Denver TMAU test

begun : Dec22
end : no ending for now

A trainee genetic counselor is working at the Denver TMAU test lab. Probably as part of her training. As a project she wishes feedback on any aspect of the Denver TMAU test and process. You can fill in the survey and/or email her (email address is in survey). It's meant for USA people, but perhaps others can give their view too (as we have so few opportunities).

quote from her rareconnect post

"Hello all! I wanted to make you aware of a research study being conducted to better understand the experience and needs of individuals with trimethylaminuria with a goal of being able to create improved patient and healthcare provider education materials. Any participation is completely voluntary and all responses remain confidential. Feel free to use the contact information within the link with any questions or share the survey with others with TMAU."

Latest FMO3 research paper : Japanese FMO3 Inter-individual variation

This is the latest FMO research paper published on pubmed, from a group of Japanese researchers at Laboratory of Drug Metabolism and Pharmacokinetics, Showa Pharmaceutical University, Tokyo, Japan. There doesn't seem to be any significant finding, other than Japanese livers seem to vary for FMO3 as much as Caucasians ? The researchers probably reearched under the perspective of FMO3 being a 'drug metabolizing enzyme', and it is likely a small % of their work. They seem to be drug metabolism researchers (pharmacokinetics) and so will FMO3 is likely a low priority to them.

FMO3 enzyme is regarded as the enzyme saturated in the case of trimethylaminuria. It is part of the group of 'xenobiotic metabolizing enzymes' which are also the main 'drug metabolizing enzymes', although FMO is still largely perceived as unimportant by medical researchers (in comparison to the other enzymes in the group). There have been around a dozen pubmed entries on FMO3 this year

Inter-individual variation in flavin-containing monooxygenase 3 in livers from Japanese: correlation with hepatic transcription factors.

Nagashima S, Shimizu M, Yano H, Murayama N, Kumai T, Kobayashi S, Guengerich FP, Yamazaki H.

Laboratory of Drug Metabolism and Pharmacokinetics, Showa Pharmaceutical University, Tokyo, Japan.

Human flavin-containing monooxygenase 3 (FMO3)-mediated microsomal oxygenation activity, levels of FMO3 protein and FMO3 mRNA and modifications were investigated in Japanese livers genotyped for the FMO3 gene. Significant correlations were observed for benzydamine N-oxygenation or methyl p-tolyl sulfide S-oxygenation activity (in the range of approximately 20- to approximately 40-fold) and FMO3 levels determined immunochemically in liver microsomes (r(2)=0.73-0.75, p less than 0.0001, n="16)." p="0.0010," n="16)," p="0.0017," n="37)."
