Trimethylaminuria is a disorder in which the volatile, fish-smelling compound, trimethylamine TMA accumulates and is excreted in the urine, but is also found in the sweat and breath of these patients. Because many patients have associated body odours or halitosis, trimethylaminuria sufferers can meet serious difficulties in a social context, leading to other problems such as isolation and depression. Primary trimethylaminuria sufferers have an inherited enzyme deficiency where TMA is not efficiently converted to the non-odorous TMAO in the liver. Secondary causes of trimethylaminuria have been described, sometimes accompanied by genetic variations. Diagnosis of trimethylaminuria requires the measurement of TMA and TMAO in urine, which should be collected after a high substrate meal in milder or intermittent cases, most simply, a marine-fish meal. The symptoms of trimethylaminuria can be improved by changes in the diet to avoid precursors, in particular TMAO which is found in high concentrations in marine fish. Treatment with antibiotics to control bacteria in the gut, or activated charcoal to sequester TMA, may also be beneficial.
Trimethylaminuria (‘fish odour syndrome’)
Important It is possible that the main title of the report Trimethylaminuria is not the name you expected. Trimethylaminuria is a rare disorder in which the body’s metabolic processes fail to alter the chemical trimethylamine. Trimethylamine is notable for its unpleasant smell. It is the chemical that gives rotten fish a bad smell. When the normal metabolic process fails, trimethylamine accumulates in the body, and its odor is detected in the person’s sweat, urine and breath.
Handbook of Hydrocarbon and Lipid Microbiology pp Cite as. The origins and metabolic transformation of trimethylamine TMA in the human body are summarized, and its role in pathological conditions described. The principal pathological conditions are 1 trimethylaminuria, an inherited metabolic condition preventing conversion of malodorous dietary TMA to trimethylamine-N-oxide TMAO , 2 dimethylaminuria, a metabolic deficiency resulting in TMA production as a result of the incomplete metabolism of dietary TMA-compounds; and 3 bacterial vaginosis, characterized by excessive TMA production, principally from the microbial reduction of TMAO.
Methylotrophic bacteria oxidize one-carbon compounds, such as the methylamines, as sources of energy for growth, and assimilate some of the carbon for cell biosynthesis. They are ubiquitous in nature and have themselves been implicated as opportunistic pathogens. It is proposed that methylamine-rich niches in the human body may provide significant habitats for such bacteria, and that they may have a role both in pathology and in body odor control.

Study record managers: refer to the Data Element Definitions if submitting registration or results information. Many yet uncharacterized medical conditions including inborn and acquired errors of metabolism or skewed microbiome could be responsible for unpredictable and uncontrollable episodes of body odor and halitosis. These conditions have dramatic impact on the quality of life and socioeconomic outcomes of sufferers.
Yet clinics and specialized malodor centers do not provide tests for diagnosing malodor other than trimethylaminuria TMAU. Self-reported odor problems are often dismissed if are not organoleptically evaluated by trained odor judges that are not readily available during malodor flare-ups.

Alternative titles; symbols. Another inborn error of metabolism accompanied by fish-like body odor results from deficiency of dimethylglycine dehydrogenase see Trimethylaminuria results from the abnormal presence of large amounts of volatile and malodorous trimethylamine within the body. This chemical, a tertiary aliphatic amine, is excreted in the urine, sweat ichthyohidrosis , and breath, which take on the offensive odor of decaying fish Mitchell, Individuals with trimethylaminuria excrete relatively large amounts of amino-trimethylamine TMA in their urine, sweat, and breath, and exhibit a fishy body odor characteristic of the malodorous free amine, leading to the designation fish-odor syndrome.
TMA is a product of intestinal bacterial action. The substrates from which it is derived are choline, which, bound to lecithin, is present most abundantly in egg yolk, liver, kidney, legumes, soy beans, and peas, as well as from trimethylamine-N-oxide, a normal constituent of saltwater fishes. Humbert et al.

Methylotrophic Bacteria in Trimethylaminuria and Bacterial Vaginosis
Living with an odor condition has not been easy. For years I lived a life of a hermit, afraid of the way people would treat me if I stepped outside of my front door. Tomorrow is another day. I will be fine. So we ate breakfast at a restaurant this morning before leaving on our trip. A few minutes later as we were seated, I see one of the waitresses go outside and walk around to the window we were facing and she stood there staring at me.
CrossRef citations to date. 7. Altmetric bacterial TMA production is believed to contribute to the symptoms of trimethylaminuria (TMAU; fish-odor syndrome).
Go back. Overview Organisations People Publications Outcomes. Abstract Funding details. A lack of active FM03 means affected individuals cannot convert odorous trimethylamine TMA , produced from breakdown of dietary choline by gut bacteria, to the non-odorous N-oxide. Social isolation, ridicule and limited employment prospects are experienced by those with TMAU, which translates to a low quality of life; high levels of depression, suicide and divorce occur in this population.
We will carry out preclinical animal studies to test a therapeutic for TMAU.

Lead Sponsor: Mebo Research, Inc. Collaborator: uBiome Aurametrix. The purpose of this study is to identify microbial signatures associated with remission and recurrence of idiopathic malodor and PATM conditions. Human odorprints, mostly owing to the microbiome, have proven their value as biomarkers of health and environmental exposures.
In recent years, microbial networks responsible for localized malodors such as halitosis or axillary odor have been mapped by using next generation sequencing approaches.

Trimethylaminuria TMAU or Fish odor syndrome is an autosomal recessive disease that is characterized by pungent body odor with subsequent psychosocial complications. There are limited studies of the sequence variants causing TMAU in the literature with most studies describing only one or two patients and lacking genotype-phenotype correlations. We have used the newly established clinical test in our institution to attempt to characterize the genotype sequence variants including mutations and polymorphisms of classical TMAU patients and to establish a genotype-phenotype biochemical and clinical association.
The questionnaire results confirmed most of the previously reported epidemiological findings of TMAU and also indicated that TMAU patients use multiple intervention measures in attempt to control their symptoms with dietary control being most effective. Despite the complexity of intervention, most patients did not have any medical follow up and there was underutilization of specialist care. Some of the latter were double heterozygous for the EK and EG polymorphisms which could explain a mild phenotype while others had only the EK variant which raised the question of undetected mutations.
These results indicate that further experiments are needed to further delineate the full mutational spectrum of the FMO3 gene.
