Only symptomatic treatment for the management of disturbances can be indicated for affected individuals. The genetic origin of this disease would indicate gene therapy holds the most promise for future development of a cure. But at this time no specific treatments for Flynn–Aird syndrome exist.

P. Flynn and Robert B. Aird observed this neuroectodermal syndrome after studying one family whose members suffered a number of neurological symptoms that were consistent from generation to generation. A number of the symptoms overlapped with several known neurological diseases such as Werner syndrome, Refsum syndrome, and Cockayne syndrome, which could be indicative of similar causative origins. However, these syndromes are recessively inherited as opposed to the dominant inheritance seen in the family studied by P. Flynn and Robert B. Aird. About 15% of family members exhibited full-blown symptoms characteristic of the disease while others showed some symptoms that overlapped with the general clinical manifestation of the syndrome.

The cause of Primrose syndrome is currently unknown. This condition is extremely rare and seems to spontaneously occur, regardless of family history.

In the case studied by Dalai et al. in 2010, it was found that an abnormally high amount of calcitonin, a hormone secreted by the thyroid gland to stabilize blood calcium levels, was present in the blood serum. This suggests that the thyroid gland is releasing an abnormal amount of calcitonin, resulting in the disruption of calcium level homeostasis. No molecular cause was found, but an expanded microarray analysis of the patient found a 225.5 kb deletion on chromosome 11p between rs12275693 and rs1442927. Whether or not this deletion is related to the syndrome or is a harmless mutation is unknown. The deletion was not present in the patient's mother's DNA sample, but the father's DNA was unavailable.

Rud syndrome is a poorly characterized disorder, probably of X-linked recessive inheritance, named after Einar Rud who described 2 patients with the case in 1927 and 1929. It was argued that all reported cases of Rud syndrome are genetically heterogeneous and significantly differ from the original case reports of Rud and that the designation Rud syndrome should be eliminated and that the patients with such diagnosis should be reassigned to other syndromes, such as Refsum disease and Sjögren-Larsson syndrome.Some consider Rud syndrome and Sjögren-Larsson syndrome the same entity and that Rud syndrome doesn't exist.

In 1929, the Danish physician Einar Rud described a 22-year-old Danish male had ichthyosis, hypogonadism, short stature, epilepsy, anemia, and polyneuritis. In 1929, he described a 29-year-old female with ichthyosis, hypogonadism, partial gigantism, and diabetes mellitus.

EAST syndrome is an autosomal recessive disorder; therefore, it cannot necessarily be prevented. Presence of the four symptoms (epilepsy, ataxia, sensorineural deafness, and salt-wasting renal tubulopathy) and detection of a mutation in the KCNJ10 gene would indicate the presence of this disorder.

There is not yet one method to help EAST syndrome as a whole, but hopefully with continued research, there could be one day.

There is no known direct treatment. Current treatment efforts focus on managing the complications of Wolfram syndrome, such as diabetes mellitus and diabetes insipidus.

Research for designing therapeutic trials is ongoing via the Washington University Wolfram Study Group, supported by The Ellie White Foundation for Rare Genetic Disorders and The Jack and J.T. Snow Scientific Research Foundation for Wolfram research.

As fat cannot be stored under the skin it is important to have a healthy diet without excess fat. Often due to failure to thrive or lack of subcutaneous fat there may have been encouragement to add supplements or fat to the diet however this will not result in any increase in fat under the skin and can easily result in it going into tissues such as the liver or kidney where it is not desired. In people with moderate / severe lipodystrophy a low fat diet would be recommended but in those where the lipodystrophy has not progressed (for example in younger children) a healthy relatively low fat diet may be sufficient. The fat and muscle reduction is not the result of dietary insufficiency and cannot be treated with dietary measures. Apart from diet the other thing that is important is exercise which should be encouraged and will make insulin work more effectively.

In those who have not developed diabetes it is recommended fasting insulin, triglycerides, glucose and HbA1c should be measured annually to monitor insulin resistance and blood glucose.

In those with diabetes it is suggested using Metformin in doses of at least 2g/day as it decreases insulin resistance and improves insulin sensitivity, following appropriate clinical consultation.

The thin skin means if there is trauma there should be rapid attention to any wounds to avoid infection and help primary healing as there can be problems with skin ulcers.

Treatment is symptomatic, often addressing indicators associated with peripheral pulmonary artery stenosis. Laryngotracheal calcification resulting in dyspnea and forceful breathing can be treated with bronchodilators including the short and long-acting β2-agonists, and various anticholinergics. Prognosis is good, yet life expectancy depends on the severity and extent of diffuse pulmonary and arterial calcification.

The common symptoms in all reported cases of primrose syndrome include ossified pinnae, learning disabilities or mental retardation, hearing problems, movement disorders (ataxia, paralysis, and parkinsonism among others (likely due, in part, to calcification of the basal ganglia), a torus palatinus (a neoplasm on the mouth's hard palate), muscle atrophy, and distorted facial features. Other symptoms usually occur, different in each case, but it is unknown whether or not these symptoms are caused by the same disease.

Some males have had undescended testes but in all cases, whether or not this was corrected, they have hypogonadism (reduced function of the testes) and many may be infertile due to inadequate testicular development. In females normal periods have been observed.

Low testosterone will require testosterone replacement. In peri-pubertal males, adequate testosterone replacement is required for its anabolic affects such as growth and also the induction of puberty with high doses. This needs to be coordinated with growth hormone replacement (if given) to avoid early closure of the epitheses (ends of the bones) which would reduce height.

A cure for Werner syndrome has not yet been discovered. It is often treated by managing the associated diseases and relieving symptoms to improve quality of life. The skin ulcers that accompany WS can be treated in several ways, depending on the severity. Topical treatments can be used for minor ulcers, but are not effective in preventing new ulcers from occurring. In the most severe cases, surgery may be required to implant a skin graft or amputate a limb if necessary. Diseases commonly associated with Werner Syndrome such as diabetes and cancer are treated in generally the same ways as they would be for a non-Werner Syndrome individual. A change in diet & exercise can help prevent and control arteriosclerosis, and regular cancer screenings can allow for early detection of cancer.

There is recent evidence that suggests that the cytokine-suppressive anti-inflammatory drug, SB203580, may be a possible therapeutic option for patients with Werner's Syndrome. This drug targets the p38 signaling pathway, which may become activated as a result of genomic instability and stalled replication forks that are characteristic mutations in WS. This activation of p38 may play a role in the onset of premature cell aging, skin aging, cataracts, and graying of the hair. The p38 pathway has also been implicated in the anti-inflammatory response that causes atherosclerosis, diabetes, and osteoporosis, all of which are associated with Werner's Syndrome. This drug has shown to revert the aged characteristics of young WS cells to those seen in normal, young cells and improve the lifespan of WS cells "in vitro". SB203580 is still in the clinical trial stages, and the same results have not yet been seen "in vivo".

In 2010, vitamin C supplementation was found to reverse the premature aging and several tissue dysfunctions in a genetically modified mouse model of the disease. Vitamin C supplementation also appeared to normalize several age-related molecular markers such as the increased levels of the transcription factor NF-κB. In addition, it decreases activity of genes activated in human Werner syndrome and increases gene activity involved in tissue repair. Supplementation of vitamin C is suspected to be beneficial in the treatment of human Werner syndrome, although there was no evidence of anti-aging activity in nonmutant mice. In general, treatments are available for only the symptoms or complications and not for the disease itself.

There is no known cure to BVVL however a Dutch group have reported the first promising attempt at treatment of the disorder with high doses of riboflavin. This Riboflavin protocol seems to be beneficial in almost all cases. Specialist medical advice is of course essential to ensure the protocol is understood and followed correctly.

Patients will almost certainly require additional symptomatic treatment and supportive care. This must be specifically customized to the needs of the individual but could include mobility aids, hearing aids or cochlear implants, vision aids, gastrostomy feeding and assisted ventilation, while steroids may or may not help patients.

The first report of BVVL syndrome in Japanese literature was of a woman that had BVVL and showed improvement after such treatments. The patient was a sixty-year-old woman who had symptoms such as sensorineural deafness, weakness, and atrophy since she was 15 years old. Around the age of 49 the patient was officially diagnosed with BVVL, incubated, and then attached to a respirator to improve her CO2 narcosis. After the treatments, the patient still required respiratory assistance during sleep; however, the patient no longer needed assistance by a respirator during the daytime.

The clinical course of BVVL can vary from one patient to another. There have been cases with progressive deterioration, deterioration followed by periods of stabilization, and deterioration with abrupt periods of increasing severity.

The syndrome has previously been considered to have a high mortality rate but the initial response of most patients to the Riboflavin protocol are very encouraging and seem to indicate a significantly improved life expectancy could be achievable. There are three documented cases of BVVL where the patient died within the first five years of the disease. On the contrary, most patients have survived more than 10 years after the onset of their first symptom, and several cases have survived 20–30 years after the onset of their first symptom.

Families with multiple cases of BVVL and, more generally, multiple cases of infantile progressive bulbar palsy can show variability in age of disease onset and survival. Dipti and Childs described such a situation in which a family had five children that had Infantile PBP. In this family, three siblings showed sensorineural deafness and other symptoms of BVVL at an older age. The other two siblings showed symptoms of Fazio-Londe disease and died before the age of two.

Various strategies have been proposed to prevent the development of metabolic syndrome. These include increased physical activity (such as walking 30 minutes every day), and a healthy, reduced calorie diet. Many studies support the value of a healthy lifestyle as above. However, one study stated these potentially beneficial measures are effective in only a minority of people, primarily due to a lack of compliance with lifestyle and diet changes. The International Obesity Taskforce states that interventions on a sociopolitical level are required to reduce development of the metabolic syndrome in populations.

The Caerphilly Heart Disease Study followed 2,375 male subjects over 20 years and suggested the daily intake of a pint (~568 ml) of milk or equivalent dairy products more than halved the risk of metabolic syndrome. Some subsequent studies support the authors' findings, while others dispute them. A systematic review of four randomized controlled trials found that a paleolithic nutritional pattern improved three of five measurable components of the metabolic syndrome in participants with at least one of the components.

EAST syndrome is a syndrome consisting of epilepsy, ataxia (a movement disorder), sensorineural deafness (deafness because of problems with the hearing nerve) and salt-wasting renal tubulopathy (salt loss caused by kidney problems). The tubulopathy (renal tubule abnormalities) in this condition predispose to hypokalemic (low potassium) metabolic alkalosis with normal blood pressure. Hypomagnesemia (low blood levels of magnesium) may also be present.

EAST syndrome is also called SeSAME syndrome, as a syndrome of seizures, sensorineural deafness, ataxia, intellectual disability (mental retardation), and electrolyte imbalances. It is an autosomal recessive genetic disorder caused by mutations in the KCNJ10 gene, as discovered by Bockenhauer and co-workers. The KCNJ10 gene encodes the K+ channel Kir.4 (allowing K+ to flow into a cell rather than out) and is present in the brain, ear, and kidney.

May–White syndrome is a rare familial progressive myoclonus epilepsy with lipomas, deafness, and ataxia. This syndrome is probably a familial form of mitochondrial encephalomyopathy.

Keutel syndrome (KS) is a rare autosomal recessive genetic disorder characterized by abnormal diffuse cartilage calcification, hypoplasia of the mid-face, peripheral pulmonary stenosis, hearing loss, short distal phalanges (tips) of the fingers and mild mental retardation. Individuals with KS often present with peripheral pulmonary stenosis, brachytelephalangism, sloping forehead, midface hypoplasia, and receding chin. It is associated with abnormalities in the gene coding for matrix gla protein (MGP). Being an autosomal recessive disorder, it may be inherited from two unaffected, abnormal MGP-carrying parents. Thus, people who inherit two affected MGP genes will likely inherit KS.

It was first identified in 1972 as a novel rare genetic disorder sharing similar symptoms with chondrodysplasia punctata. Multiple forms of chondrodysplasia punctata share symptoms consistent with KS including abnormal cartilage calcification, forceful respiration, brachytelephalangism, hypotonia, psychomotor delay, and conductive deafness, yet peripheral pulmonary stenosis remains unique to KS.

No chromosomal abnormalities are reported in affected individuals, suggesting that familial consanguinity relates to the autosomal recessive mode of inheritance. Also, despite largely abnormal calcification of regions including the larynx, tracheobronchial tree, nose, pinna (anatomy), and epiglottis, patients exhibit normal serum calcium and phosphate levels.

The first line treatment is change of lifestyle (e.g., Dietary Guidelines for Americans and physical activity). However, if in three to six months of efforts at remedying risk factors prove insufficient, then drug treatment is frequently required. Generally, the individual disorders that compose the metabolic syndrome are treated separately. Diuretics and ACE inhibitors may be used to treat hypertension. Cholesterol drugs may be used to lower LDL cholesterol and triglyceride levels, if they are elevated, and to raise HDL levels if they are low. Use of drugs that decrease insulin resistance, e.g., metformin and thiazolidinediones, is controversial; this treatment is not approved by the U.S. Food and Drug Administration. Weight loss medications may result in weight loss. As obesity is often recognized as the culprit behind many of the additional symptoms, with weight loss and lifestyle changes in diet, physical activity, the need for other medications may diminish.

A 2003 study indicated cardiovascular exercise was therapeutic in approximately 31% of cases. The most probable benefit was to triglyceride levels, with 43% showing improvement; but fasting plasma glucose and insulin resistance of 91% of test subjects did not improve.

Many other studies have supported the value of physical activity and dietary modifications to treat metabolic syndrome. Some natural compounds, like ursolic acid, have been suggested as a treatment for obesity/metabolic syndrome based on the results of extensive research involving animal models; it is argued, however, that there is still a lack of data regarding the use of ursolic acid in humans, as phase-II/III trials of that drug have not been carried so far.

Restricting the overall dietary carbohydrate intake is more effective in reducing the most common symptoms of metabolic syndrome than the more commonly prescribed reduction in dietary fat intake.

The combination preparation simvastatin/sitagliptin (marketed as Juvisync) was introduced in 2011 and the use of this drug was to lower LDL levels and as well as increase insulin levels. This drug could have been used to treat metabolic syndrome but was removed from the market by Merck in 2013 due to business reasons.

High-dose statins, recommended to reduce cardiovascular risk, have been associated with higher progression to diabetes, particularly in patients with metabolic syndrome. The biological mechanisms are not entirely understood, however, the plausible explanation may lie in competitive inhibition of glucose transport via the solute carrier (SLC) family of transporters (specifically "SLCO1B1"), important in statin pharmacokinetics.

Some studies on mice suggest that a Time Restricted Diet (TRD) could be helpful in reversing obesity and possibly metabolic syndrome

Dunnigan-type familial partial lipodystrophy, also known as FPLD Type II and abbreviated as (FPLD2), is a rare monogenic form of insulin resistance characterized by loss of subcutaneous fat from the extremities, trunk, and gluteal region. FPLD recapitulates the main metabolic attributes of the insulin resistance syndrome, including central obesity, hyperinsulinemia, glucose intolerance and diabetes usually type 2, dyslipidemia, hypertension, and early endpoints of atherosclerosis. It can also result in hepatic steatosis. FPLD results from mutations in LMNA gene, which is the gene that encodes nuclear lamins A and C.

The journal of child neurology published a paper in 2012, Buccal swab analysis of mitochondrial enzyme deficiency and DNA defects in a child with suspected myoclonic epilepsy and ragged red fibers (MERRF), discusses possible new methods to test for MERRF and other mitochondrial diseases, through a simple swabbing technique. This is a less invasive techniques which allows for an analysis of buccal mitochondrial DNA, and showed significant amounts of the common 5 kb and 7.4 kb mitochondrial DNA deletions, also detectable in blood. This study suggests that a buccal swab approach can be used to informatively examine mitochondrial dysfunction in children with seizures and may be applicable to screening mitochondrial disease with other clinical presentations.

Proceedings of the National Academy of Science of the United States of America published an article in 2007 which investigate the human mitochondrial tRNA (hmt-tRNA) mutations which are associated with mitochondrial myopathies. Since the current understanding of the precise molecular mechanisms of these mutations is limited, there is no efficient method to treat their associated mitochondrial diseases. All pathogenic mutants displayed pleiotropic phenotypes, with the exception of the G34A anticodon mutation, which solely affected aminoacylation.

Like many mitochondrial diseases, there is no cure for MERRF, no matter the means for diagnosis of the disease. The treatment is primarily symptomatic. High doses of Coenzyme Q10, B complex vitamins and L-Carnitine are the drugs that patients are treated with in order to account for the altered metabolic processed resulting in the disease. There is very little success with these treatments as therapies in hopes of improving mitochondrial function. The treatment only alleviates symptoms and these do not prevent the disease from progressing. Patients with concomitant disease, such as diabetes, deafness or cardiac disease, are treated in combination to manage symptoms.

The pathogenesis of this disease is unclear. Arteriosclerosis obliterans has been postulated as the cause, along with errors of the clotting and fibrinolytic pathways such as antiphospholipid syndrome.

Both conditions are treated with fibrate drugs, which act on the peroxisome proliferator-activated receptors (PPARs), specifically PPARα, to decrease free fatty acid production. Statin drugs, especially the synthetic statins (atorvastatin and rosuvastatin), can decrease LDL levels by increasing hepatic reuptake of LDL due to increased LDL-receptor expression.
