Hi Dr. Manning,
We live in the States and have a teenaged son who has sporadically had a fecal/moth ball type of odor. I would say that it didn't start until he was about seven. We have tried just about everything to find out its cause (GI docs, tonsils removed, etc...) This past winter I found TMAU on the internet. We took him off most choline and the smell disappeared. We then went thru Monell Chemical Senses institute and Dr. George Preti and gave him a choline challenge. That brought about no odor at all and the test was negative. So, we reintroduced choline and the smell is back. I have read about TMAU2 and am wondering if this could be what he has. Dr. Preti says he has never heard of this. Any suggestions???
Thanks so much,
