Ellie James, 44, has the rare condition known as Trimethylaminuria (TMAU), which prevents the body from breaking down materials found in certain foods. [9], Most cases of trimethylaminuria appear to be inherited in an autosomal recessive pattern, which means two copies of the gene in each cell are altered. Diagnosis and management of trimethylaminuria (FMO3 deficiency) in children. Paula Thomas, 45, from Bristol, has trimethylaminuria (TMAU), which prevents the body from breaking down materials found in certain foods. When secondary trimethylaminuria develops as a result of large oral doses of L-carnitine, choline or lecithin, the symptoms disappear as the dosage is lowered. Mol. If the enzyme is missing or its activity is reduced because of a mutation in the FMO3 gene, trimethylamine is not broken down and instead builds up in the body. This is a relatively rare disorder but the incidence of heterozygous carriers in the white British population has been suggested to be as high as 1.0%. TTY: (866) 411-1010 Primary Trimethylaminuria.
