Can trimethylaminuria occur at any time?

Yes: some people have a milder case. you should get a complete evaluation by a clinical geneticist for this autosomal recessive disorder. There may be other causes of the symptoms. trimethylamine is produced by bacteria in the intestine during the digestion of proteins from eggs, liver, legumes (such as soybeans and peas), other foods. you must see: http://ghr.nlm.nih.gov/condition/trimethylaminuria
