There is no known cure or treatment for the disorder.

The metabolic and clinical manifestations of TMAU are generally regarded as benign, as there is no associated organ dysfunction. This

designation, and the fact that the condition is often unrecognised by doctors, can have important ramifications including missed or delayed diagnosis.

Affected individuals experience shame and embarrassment, fail to maintain relationships, avoid contact with people who comment on their condition, and are obsessive about masking the odour with hygiene products and even smoking. The malodorous aspect can have serious and destructive effects on schooling, personal life, career and relationships, resulting in social isolation, low self-esteem, depression, paranoid behaviour, and suicide. Delayed diagnosis, body odour and the lack of cure may lead to psychosocial issues. When the condition is suspected or known to occur in a family, genetic testing can be helpful in identifying the specific individuals who have or carry the disorder.

Ways of reducing the fishy odor may include:

- Avoiding foods such as egg yolks, legumes, red meats, fish, beans and other foods that contain choline, carnitine, nitrogen, sulfur and lecithin

- Taking low doses of antibiotics such as neomycin and metronidazole in order to reduce the amount of bacteria in the gut

- Using slightly acidic detergent with a pH between 5.5 and 6.5

Additionally, at least one study has suggested that daily intake of the supplements activated charcoal and copper chlorophyllin may improve the quality of life of individuals afflicted with TMAU by helping their bodies to oxidize and convert TMA to the odorless "N"-oxide (TMAO) metabolite. Study participants experienced subjective reduction in odor as well as objective reduction in TMA and increase in TMAO concentration measured in their urine. The study found that:

- 85% of test participants experienced complete loss of detectable "fishy" odor

- 10% experienced some reduction in detectable odor

- 5% did not experience any detectable odor reduction

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. The parents of an individual with an autosomal recessive disorder are both carriers of one copy of the altered gene. Carriers may have mild symptoms of trimethylaminuria or experience temporary episodes of fish-like body odor.

Mutations in the "FMO3" gene, which is found on the long arm of chromosome 1, cause trimethylaminuria. The "FMO3" gene makes an enzyme that breaks down nitrogen-containing compounds from the diet, including trimethylamine. These compounds are produced by bacteria in the intestine as they digest proteins from eggs, meat, soy, and other foods. Normally, the "FMO3" enzyme converts fishy-smelling trimethylamine into trimethylamine "N"-oxide which has no odor. 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. As the compound is released in a person's sweat, urine, and breath, it causes the strong odor characteristic of trimethylaminuria. Researchers believe that stress and diet also play a role in triggering symptoms.

There are more than 40 known mutations associated with TMAU. Loss-of-function mutations, nonsense mutations, and missense mutations are three of the most common. Nonsense and missense mutations cause the most severe phenotypes.

Although "FMO3" mutations account for most known cases of trimethylaminuria, some cases are caused by other factors. A fish-like body odor could result from an excess of certain proteins in the diet or from an increase in bacteria in the digestive system. A few cases of the disorder have been identified in adults with liver damage caused by hepatitis.

In 2007 the evolution of the "FMO3" gene was studied, including the evolution of some mutations associated with TMAU.

2,4 Dienoyl-CoA reductase deficiency is an inborn error of metabolism resulting in defective fatty acid oxidation caused by a deficiency of the enzyme 2,4 Dienoyl-CoA reductase. Lysine degradation is also affected in this disorder leading to hyperlysinemia. The disorder is inherited in an autosomal recessive manner, meaning an individual must inherit mutations in "NADK2," located at 5p13.2 from both of their parents. NADK2 encodes the mitochondrial NAD kinase. A defect in this enzyme leads to deficient mitochondrial nicotinamide adenine dinucleotide phosphate levels. 2,4 Dienoyl-CoA reductase, but also lysine degradation are performed by NADP-dependent oxidoreductases explaining how NADK2 deficiency can lead to multiple enzyme defects.

2,4-Dienoyl-CoA reductase deficiency was initially described in 1990 based on a single case of a black female who presented with persistent hypotonia. Laboratory investigations revealed elevated lysine, low levels of carnitine and an abnormal acylcarnitine profile in urine and blood. The abnormal acylcarnitine species was eventually identified as 2-trans,4-cis-decadienoylcarnitine, an intermediate of linoleic acid metabolism. The index case died of respiratory failure at four months of age. Postmortem enzyme analysis on liver and muscle samples revealed decreased 2,4-dienoyl-CoA reductase activity when compared to normal controls. A second case with failure to thrive, developmental delay, lactic acidosis and severe encephalopathy was reported in 2014.

2,4-Dienoyl-CoA reductase deficiency was included as a secondary condition in the American College of Medical Genetics Recommended Uniform Panel for newborn screening. Its status as a secondary condition means there was not enough evidence of benefit to include it as a primary target, but it may be detected during the screening process or as part of a differential diagnosis when detecting conditions included as primary target. Despite its inclusion in newborn screening programs in several states for a number of years, no cases have been identified via neonatal screening.

Type 1 tyrosinemia, also known as hepatorenal tyrosinemia or tyrosinosis, is the most severe form of tyrosinemia, a buildup of too much of the amino acid tyrosine in the blood and tissues due to an inability to metabolize it. It is caused by a deficiency of the enzyme fumarylacetoacetate hydrolase.

Most patients with hyper IgE syndrome are treated with long-term antibiotic therapy to prevent staphylococcal infections. Good skin care is also important in patients with hyper IgE syndrome. High-dose intravenous gamma-globulin has also been suggested for the treatment of severe eczema in patients with HIES and atopic dermatitis.

The primary treatment for type 1 tyrosinemia is nitisinone (Orfadin) and restriction of tyrosine in the diet. Nitisinone inhibits the conversion of 4-OH phenylpyruvate to homogentisic acid by 4-Hydroxyphenylpyruvate dioxygenase, the second step in tyrosine degradation. By inhibiting this enzyme, the accumulation of the fumarylacetoacetate is prevented. Previously, liver transplantation was the primary treatment option and is still used in patients in whom nitisinone fails.

Netherton syndrome is a severe, autosomal recessive form of ichthyosis associated with mutations in the "SPINK5" gene. It is named after Earl W. Netherton (1910–1985), an American dermatologist who discovered it in 1958.

There is no known cure at the moment but there are several things that can be done to relieve the symptoms. Moisturising products are very helpful to minimize the scaling/cracking, and anti-infective treatments are useful when appropriate because the skin is very susceptible to infection. Extra protein in the diet during childhood is also beneficial, to replace that which is lost through the previously mentioned "leaky" skin.

Steroid and retinoid products have been proven ineffective against Netherton syndrome, and may in fact make things worse for the affected individual.

Intravenous immunoglobulin has become established as the treatment of choice in Netherton's syndrome. This therapy reduces infection; enables improvement and even resolution of the skin and hair abnormalities, and dramatically improves quality of life of the patients; although exactly how it achieves this is not known. Given this; it is possible that the reason Netherton's usually is not very severe at or shortly after birth is due to a protective effect of maternal antibodies; which cross the placenta but wane by four to six months.

Although the pathogenesis of HHS remains unknown, it is strongly suspected that the clinical sequelae of HHS arise from the accelerated telomere shortening present in HHS patients.

Abnormal neutrophil chemotaxis due to decreased production of interferon gamma by T lymphocytes is thought to cause the disease.

Both autosomal dominant and recessive inheritance have been described:

Autosomal dominant:

- "STAT3" may present as HIES with characteristic facial, dental, and skeletal abnormalities that has been called Job's Syndrome. A common mnemonic used to remember the symptoms is FATED: coarse or leonine facies, cold staph abscesses, retained primary teeth, increased IgE, and dermatologic problems [eczema]. The disease was linked to mutations in the "STAT3" gene after cytokine profiles indicated alterations in the STAT3 pathway.

Autosomal recessive:

- "DOCK8 -" DOCK8 Immunodeficiency Syndrome (DIDS) presents primarily with immune effects including HEIS. Eczema is prominent, food and environmental allergies are common, and asthma and anaphylaxis has been variably reported.

- "PGM3", a Congenital Disorder of Glycosylation, may present as HIES with neurocognitive impairment and hypomyelination. See PGM3 deficiency.

- "SPINK5" may present as HIES with skin and hair effects such as trichorrhexis invaginata (bamboo hair). See Netherton Syndrome (NTS).

- "TYK2" may present as HIES, although more often only with immunodeficiency.

Primary hyperoxaluria is a rare condition (autosomal recessive), resulting in increased excretion of oxalate (up to 600mg a day from normal 50mg a day), with oxalate stones being common.

As many as 90% of Americans and 92% of teenagers use antiperspirants or deodorants. In 2014, the global market for deodorants was estimated at 13.00 billion USD with a compound annual growth rate of 5.62% between 2015 and 2020.

Treatment is supportive.

- The aplastic anemia and immunodeficiency can be treated by bone marrow transplantation.

- Supportive treatment for gastrointestinal complications and infections.

- Genetic counselling.

There are three main types of primary hyperoxaluria, each associated with specific metabolic defects. Type 1 is the most common and rapidly progressing form, accounting for about 80% of all cases. Type 2 and 3 account for about approximately 10% each of the population.

Mutations in these genes cause a decreased production or activity of the proteins they make, which stops the normal breakdown of glyoxylate.

Body odor may be reduced or prevented or even aggravated by using deodorants, antiperspirants, disinfectants, underarm liners, triclosan, special soaps or foams with antiseptic plant extracts such as ribwort and liquorice, chlorophyllin ointments and sprays topically, and chlorophyllin supplements internally. Although body odor is commonly associated with hygiene practices, its presentation can be affected by changes in diet as well as the other factors.

The complement system is part of the innate as well as the adaptive immune system; it is a group of circulating proteins that can bind pathogens and form a membrane attack complex. Complement deficiencies are the result of a lack of any of these proteins. They may predispose to infections but also to autoimmune conditions.

A survey of 10,000 American households revealed that the prevalence of diagnosed primary immunodeficiency approaches 1 in 1200. This figure does not take into account people with mild immune system defects who have not received a formal diagnosis.

Milder forms of primary immunodeficiency, such as selective immunoglobulin A deficiency, are fairly common, with random groups of people (such as otherwise healthy blood donors) having a rate of 1:600. Other disorders are distinctly more uncommon, with incidences between 1:100,000 and 1:2,000,000 being reported.

Primary erythromelalgia may be classified as either familial or sporadic, with the familial form inherited in an autosomal dominant manner. Both of these may be further classified as either juvenile or adult onset. The juvenile onset form occurs prior to age 20 and frequently prior to age 10. While the genetic cause of the juvenile and sporadic adult onset forms is often known, this is not the case for the adult onset familial form.

In rural areas of southern China, outbreaks of erythromelalgia have occurred during winter and spring at 3-5 year intervals among secondary school students. This epidemic form of erythromelalgia has been viewed as a different form of non-inherited primary erythromelalgia and affects mainly teenage girls in middle schools.

Autosomal recessive polycystic kidney disease (ARPKD) is the recessive form of polycystic kidney disease. It is associated with a group of congenital fibrocystic syndromes. Mutations in the "PKHD1" (chromosomal locus 6p12.2) cause ARPKD.

The consumption of two species of related fungi, "Clitocybe acromelalga" from Japan, and "Clitocybe amoenolens" from France, has led to several cases of mushroom-induced erythromelalgia which lasted from 8 days to 5 months.

Ruminal tympany, also known as bloat, is a disease of ruminant animals, characterized by an excessive volume of gas in the rumen. Ruminal tympany may be primary, known as frothy bloat, or secondary, known as free-gas bloat.

In the rumen, food eaten by the ruminant is fermented by microbes. This fermentation process continually produces gas, the majority of which is expelled from the rumen by eructation (burping). Ruminal tympany occurs when this gas becomes trapped in the rumen.

In frothy bloat (primary ruminal tympany), the gas produced by fermentation is trapped within the fermenting material in the rumen, causing a build up of foam which cannot be released by burping. In cattle, the disease may be triggered after an animal eats a large amount of easily fermenting plants, such the legumes alfalfa, red clover, or white clover. Some legumes, such as sainfoin, birdsfoot trefoil and cicer milkvetch are not associated with cause bloat in cattle. In feedlot cattle, a diet containing a high proportion of cereal grain can lead to primary ruminal tympany. The main signs in cattle are distension of the left side of the abdomen, dyspnea (difficulty breathing) and severe distress. If gas continues to accumulate, the right side of the abdomen may also become distended, with death occurring in cattle within 3–4 hours after symptoms begin.

In free-gas bloat (secondary ruminal tympany), gas builds up in the rumen and cannot escape, due to blockage of the esophagus.

Treatment:

1-Removal of gases through Trochor or canula

2-Use Stomach tube and remove the ruminal digesta

3-medi oral (anti foaming agent) 10ml+250ml warm water and drench to the animal

if antifoaming agent not available you can use Vegetable oil 400-500ml per large animal

4-use rexa bicarb

5-Nux vomica

6-Anti histamine is used to avoid lameness*

A ciliopathy is a genetic disorder of the cellular cilia or the cilia anchoring structures, the basal bodies, or of ciliary function.

Although ciliopathies are usually considered to involve proteins that localize to motile and/or immotile (primary) cilia or centrosomes, it is possible for ciliopathies to be associated with proteins such as XPNPEP3, which localizes to mitochondria but is believed to affect ciliary function through proteolytic cleavage of ciliary proteins.

Significant advances in understanding the importance of cilia were made beginning in the mid-1990s. However, the physiological role that this organelle plays in most tissues remains elusive. Additional studies of how ciliary dysfunction can lead to such severe disease and developmental pathologies is a subject of current research.

Although primary polydipsia is usually categorised as psychogenic, there are some rare non-psychogenic causes. An example is polydipsia found in patients with autoimmune chronic hepatitis with severely elevated globulin levels. Evidence for the thirst being non-psychogenic is gained from the fact that it disappears after treatment of the underlying disease.

Psychogenic polydipsia is found in patients with mental illnesses, most commonly schizophrenia, but also anxiety disorders and rarely affective disorders, anorexia nervosa and personality disorders. PPD occurs in between 6% and 20% of psychiatric inpatients. It may also be found in people with developmental disorders, such as those with autism. While psychogenic polydipsia is usually not seen outside the population of those with serious mental disorders, it may occasionally be found among others in the absence of psychosis, although there is no existent research to document this other than anecdotal observations. Such persons typically prefer to possess bottled water that is ice-cold, consume water and other fluids at excessive levels. However, a preference for ice-cold water is also seen in diabetes insipidus.

Ultrasonography is the primary method to evaluate autosomal recessive polycystic kidney disease, particularly in the perinatal and neonatal.
