"GSTT1 Present" - what are the implications?


Senior Member
If it's present - good for you!

GSTT1 - If it’s absent, you’re missing one of the genes that produce glutathione. This is worse than simply having a mutation. Approximately 15% of the population has this. You may have trouble with xenobiotics (environmental toxins), mercury, etc. Treatment would be to avoid toxins and do methylation treatment and/or other measures to raise glutathione.

From the SNPs Interpretation Guide - see my signature link for this and other useful methylation documents, videos and links.
