Denver TMAU Test Lab survey click here
click to Read more/less

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."

Table of FMO3 variants provided by Dr John Cashman

Table of FMO3 variants provided by Dr John Cashman 

Dr John Cashman kindly provided some of his research papers for us to view at the Washington meetup. We have chosen to look at the table of FMO3 variants in one of these papers.

As seen in Prof Elizabeth Shephard's slideshow, the FMO3 protein consists of 532 amino acids. Whilst building these amino acids, in theory it means there could be 532 points where mutations could occur that would affect the construction of the final FMO3 protein.

In this table, Dr Cashman has listed some of the common amino acid numbers where mutations occur. Some are severe mutations, other have less or no effect, although some can reduce activity if in combination with another (such as 158 - 258)

Notice that one change to amino acid 158 is about 40% common in ethnic groups.

2.5% have a combo of 158 - 308 which is said to be present in 2.5% of the population. However, this is only regarded as likely to cause a mild deficiency in FMO3 function if both the mutations are on the same chromosome (i.e. from the same parent) .

The paper also lists some drugs that commonly use FMO3 function and the affect a deficiency may have on them.
