DNA testing at 23andme.com

We have mentioned before that 23andme.com genetic testing service is an inexpensive way of getting your genome tested, including for the FMO3 enzyme associated with genetic trimethylaminuria (usually around $199). Sometimes they do special offers where it is even cheaper. Currently they are offering their DNA test for $99 plus shipping, as long as a $9 a month subscription to their online service is also taken for a year (check details).

23andme.com is owned by the wife of one of the Google founders. They use SNP chips for testing.

Many genetic disorders are listed and easy to find out if you are a carrier or have the disorder. However, trimethylaminuria is not one of those listed, and you have to delve into the 'raw data' and interpret it, which to most non-experts would be nigh impossible. Currently there are 56 SNPs for FMO3 listed in the raw data, and we hope to get an expert to help us compile a table so that people can generally interpret their FMO3 DNA result using 23andme.com.

We will keep you updated and post a table here when possible.

Those wishing not to know their risk to other diseases such as cancers or Alzheimer disease should not tick the box shown when they first go to their results page.

The sample is taken via a saliva sample sent by mail. Some States do not allow consumer genetic testing (NY State ?). The only way around this is to get the kit sent to an address in another State.
