The World Anti-Doping Agency (WADA) is the main regulatory organization looking into the issue of the detection of gene doping. Both direct and indirect testing methods are being researched by the organization. Directly detecting the use of gene therapy usually requires the discovery of recombinant proteins or gene insertion vectors, while most indirect methods involve examining the athlete in an attempt to detect bodily changes or structural differences between endogenous and recombinant proteins.

Indirect methods are by nature more subjective, as it becomes very difficult to determine which anomalies are proof of gene doping, and which are simply natural, though unusual, biological properties. For example, Eero Mäntyranta, an Olympic cross country skier, had a mutation which made his body produce abnormally high amounts of red blood cells. It would be very difficult to determine whether or not Mäntyranta's red blood cell levels were due to an innate genetic advantage, or an artificial one.

Modulating the levels of proteins that affect psychology are also potential goals for gene doping; for example pain perception depends on endorphins and enkephalins, response to stress depends on BDNF, and an increase in synthesis of monamines could improve the mood of athletes. Preproenkephalin has been administered via gene therapy using a replication-deficient herpes simplex virus, which targets nerves, to mice with results good enough to justify a Phase I clinical trial in people with terminal cancer with uncontrolled pain. Adopting that approach for athletes would be problematic since the pain deadening would likely be permanent.

VEGF has been tested in clinical trials to increase blood flow and has been considered as a potential gene doping agent; however long term follow up of the clinical trial subjects showed poor results. The same is true of fibroblast growth factor. Glucagon-like peptide-1 increases the amount of glucose in the liver and has been administered via gene therapy to the livers of mouse models of diabetes and was shown to increase gluconeogenesis' for athletes this would make more energy available and reduce the buildup of lactic acid.

The standard treatment is chenodeoxycholic acid (CDCA) replacement therapy. Serum cholesterol levels are also followed. If hypercholesterolemia is not controlled with CDCA, an HMG-CoA reductase inhibitor ("statins" such as simvastatin) can also be used.

Currently, there is no cure for laminopathies and treatment is largely symptomatic and supportive. Physical therapy and/or corrective orthopedic surgery may be helpful for patients with muscular dystrophies. Cardiac problems that occur with some laminopathies may require a pacemaker. Treatment for neuropathies may include medication for seizures and spasticity.

The recent progress in uncovering the molecular mechanisms of toxic progerin formation in laminopathies leading to premature aging has opened up the potential for the development of targeted treatment. The farnesylation of prelamin A and its pathological form progerin is carried out by the enzyme farnesyl transferase. Farnesyl transferase inhibitors (FTIs) can be used effectively to reduce symptoms in two mouse model systems for progeria and to revert the abnormal nuclear morphology in progeroid cell cultures. Two oral FTIs, lonafarnib and tipifarnib, are already in use as anti-tumor medication in humans and may become avenues of treatment for children suffering from laminopathic progeria. Nitrogen-containing bisphosphate drugs used in the treatment of osteoporosis reduce farnesyldiphosphate production and thus prelamin A farnesylation. Testing of these drugs may prove them to be useful in treating progeria as well. The use of antisense oligonucleotides to inhibit progerin synthesis in affected cells is another avenue of current research into the development of anti-progerin drugs.

CGL patients have to maintain a strict diet for life, as their excess appetite will cause them to overeat. Carbohydrate intake should be restricted in these patients. To avoid chylomicronemia, CGL patients with hypertriglyceridemia need to have a diet very low in fat. CGL patients also need to avoid total proteins, trans fats, and eat high amounts of soluble fiber to avoid getting high levels of cholesterol in the blood.

Metformin is the main drug used for treatment, as it is normally used for patients with hyperglycemia. Metformin reduces appetite and improves symptoms of hepatic steatosis and polycystic ovary syndrome. Leptin can also be used to reverse insulin resistance and hepatic steatosis, to cause reduced food intake, and decrease blood glucose levels.

There is no cure and no standard course of treatment for Coffin–Lowry syndrome. Treatment is symptomatic and supportive, and may include occupational, physical and speech therapy and educational services.

Pancreatic exocrine insufficiency may be treated through pancreatic enzyme supplementation, while severe skeletal abnormalities may require surgical intervention. Neutropenia may be treated with granulocyte-colony stimulating factor (GCSF) to boost peripheral neutrophil counts. However, there is ongoing and unresolved concern that this drug could contribute to the development of leukemia. Signs of progressive marrow failure may warrant bone marrow transplantation (BMT). This has been used successfully to treat hematological aspects of disease. However, SDS patients have an elevated occurrence of BMT-related adverse events, including graft-versus-host disease (GVHD) and toxicity relating to the pre-transplant conditioning regimen. In the long run, study of the gene that is mutated in SDS should improve understanding of the molecular basis of disease. This, in turn, may lead to novel therapeutic strategies, including gene therapy and other gene- or protein-based approaches.

Treatments include discontinuation of protein intake, intravenous infusion of glucose and, as needed, infusion of supplemental arginine and the ammonia removal drugs, sodium phenylacetate and sodium benzoate.

Treatment of Wiskott–Aldrich syndrome is currently based on correcting symptoms. Aspirin and other nonsteroidal anti-inflammatory drugs should be avoided, since these may interfere with platelet function. A protective helmet can protect children from bleeding into the brain which could result from head injuries. For severely low platelet counts, patients may require platelet transfusions or removal of the spleen. For patients with frequent infections, intravenous immunoglobulins (IVIG) can be given to boost the immune system. Anemia from bleeding may require iron supplementation or blood transfusion.

As Wiskott–Aldrich syndrome is primarily a disorder of the blood-forming tissues, a hematopoietic stem cell transplant, accomplished through a umbilical cord blood or bone marrow transplant offers the only current hope of cure. This may be recommended for patients with HLA-identical donors, matched sibling donors, or even in cases of incomplete matches if the patient is age 5 or under.

Studies of correcting Wiskott–Aldrich syndrome with gene therapy using a lentivirus have begun.

Proof-of-principle for successful hematopoietic stem cell gene therapy has been provided for patients with Wiskott–Aldrich syndrome.

Currently, many investigators continue to develop optimized gene therapy vectors. In July 2013 the Italian San Raffaele Telethon Institute for Gene Therapy (HSR-TIGET) reported that three children with Wiskott–Aldrich syndrome showed significant improvement 20–30 months after being treated with a genetically modified lentivirus. In April 2015 results from a follow-up British and French trial where six children with Wiskott–Aldrich syndrome were treated with gene therapy were described as promising. Median follow-up time was 27 months.

Treatment can include amoxicillin-clavulanic acid, intravenous fluid administration and paracetamol oral for pain relief. Other treatment varies based on the condition and extent of uropathy.

The most commonly effective treatment is clonazepam, which leads to the increased efficacy of another inhibitory neurotransmitter, GABA. There are anecdotal reports of the use of Levetiracetam in genetic and acquired hyperekplexia. During attacks of hypertonia and apnea, the limbs and head may be flexed towards the trunk in order to dissipate the symptoms. This is named the Vigevano maneuver after the doctor who invented it.

Oral retinoids have proven effective in treating this disorder. Depending on the side effects they may improve the quality of life. Examples are etretinate, acitretin, isotretinoin

The treatment of genetic disorders is an ongoing battle with over 1800 gene therapy clinical trials having been completed, are ongoing, or have been approved worldwide. Despite this, most treatment options revolve around treating the symptoms of the disorders in an attempt to improve patient quality of life.

Gene therapy refers to a form of treatment where a healthy gene is introduced to a patient. This should alleviate the defect caused by a faulty gene or slow the progression of disease. A major obstacle has been the delivery of genes to the appropriate cell, tissue, and organ affected by the disorder. How does one introduce a gene into the potentially trillions of cells which carry the defective copy? This question has been the roadblock between understanding the genetic disorder and correcting the genetic disorder.

Treatments focuses on symptoms, with genetic counseling recommended.

Cheating at the Paralympic Games has caused scandals that have significantly changed the way in which the International Paralympic Committee (IPC) manages the events.

Testing for performance-enhancing drugs has become increasingly strict and more widespread throughout the Games, with powerlifting seeing the most positive results. Competitors without disabilities have also competed in some Paralympic Games, with the Spanish entry in the intellectually disabled basketball tournament at the 2000 Summer Paralympics being the most controversial.

States that agree to the Convention align their domestic rules with the World Anti-Doping Code, which is promulgated by the World Anti-Doping Agency. This includes facilitating doping controls and supporting national testing programmes; encouraging the establishment of "best practice" in the labelling, marketing, and distribution of products that might contain prohibited substances; withholding financial support from those who engage in or support doping; taking measures against manufacturing and trafficking; encouraging the establishment of codes of conduct for professions relating to sport and anti-doping; and funding education and research on drugs in sport.

One form of LCA, patients with LCA2 bearing a mutation in the RPE65 gene, has been successfully treated in clinical trials using gene therapy. The results of three early clinical trials were published in 2008 demonstrating the safety and efficacy of using adeno-associated virus to deliver gene therapy to restore vision in LCA patients. In all three clinical trials, patients recovered functional vision without apparent side-effects. These studies, which used adeno-associated virus, have spawned a number of new studies investigating gene therapy for human retinal disease.

The results of a phase 1 trial conducted by the University of Pennsylvania and Children’s Hospital of Philadelphia and published in 2009 showed sustained improvement in 12 subjects (ages 8 to 44) with RPE65-associated LCA after treatment with AAV2-hRPE65v2, a gene replacement therapy. Early intervention was associated with better results. In that study, patients were excluded based on the presence of particular antibodies to the vector AAV2 and treatment was only administered to one eye as a precaution. A 2010 study testing the effect of administration of AAV2-hRPE65v2 in both eyes in animals with antibodies present suggested that immune responses may not complicate use of the treatment in both eyes.

Eye Surgeon Dr. Al Maguire and gene therapy expert Dr. Jean Bennett developed the technique used by the Children's Hospital.

Dr. Sue Semple-Rowland at the University of Florida has recently restored sight in an avian model using gene therapy.

The International Convention against Doping in Sport is a multilateral UNESCO treaty by which states agree to adopt national measures to prevent and eliminate drug doping in sport.

Not all genetic disorders directly result in death, however there are no known cures for genetic disorders. Many genetic disorders affect stages of development such as Down syndrome. While others result in purely physical symptoms such as muscular dystrophy. Other disorders, such as Huntington's disease show no signs until adulthood. During the active time of a genetic disorder, patients mostly rely on maintaining or slowing the degradation of quality of life and maintain patient autonomy. This includes physical therapy, pain management, and may include a selection of alternative medicine programs.

Diagnosis

Originally NEMO deficiency syndrome was thought to be a combination of Ectodermal Dysplasia (ED) and a lack of immune function, but is now understood to be more complex disease. NEMO Deficiency Syndrome may manifest itself in the form of several different diseases dependent upon mutations of the IKBKG gene such as Incontinentia pigmenti or Ectodermal dysplasia.

The clinical presentation of NEMO deficiency is determined by three main symptoms:

1. Susceptibility to pyogenic infections in the form of severe local inflammation

2. Susceptibility to mycobacterial infection

3. Symptoms of Ectodermal Dysplasia

To determine whether or not patient has NEMO deficiency, an immunologic screen to test immune system response to antigen may be used although a genetic test is the only way to be certain as many individuals respond differently to the immunological tests.

Commonly Associated Diseases

NEMO deficiency syndrome may present itself as Incontinentia pigmenti or Ectodermal dysplasia depending on the type of genetic mutation present, such as if the mutation results in the complete loss of gene function or a point mutation.

Amorphic genetic mutations in the IKBKG gene, which result in the loss of gene function, typically present themselves as Incontinetia Pigmenti (IP). Because loss of NEMO function is lethal, only heterozygous females or males with XXY karyotype or mosaicism for this gene survive and exhibit symptoms of Incontinetia Pigmenti, such as skin lesions and abnormalities in hair, teeth, and nails. There are a variety of mutations that may cause the symptoms of IP, however, they all involve the deletion of exons on the IKBKG gene.

Hypomorphic genetic mutations in the IKBKG gene, resulting in a partial loss of gene function, cause the onset of Anhidrotic ectodermal dysplasia with Immunodeficiency (EDA-IP). The lack of NEMO results in a decreased levels of NF-κB transcription factor translocation and gene transcription, which in turn leads to a low level of immunoglobulin production. Because NF-κB translocation is unable to occur without proper NEMO function, the cell signaling response to immune mediators such as IL-1β, IL-18, and LPS are ineffective thus leading to a compromised immune response to various forms of bacterial infections.

Treatment

The aim of treatment is to prevent infections so children will usually be started on immunoglobulin treatment. Immunoglobulin is also known as IgG or antibody. It is a blood product and is given as replacement for people who are unable to make their own antibodies. It is the mainstay of treatment for patients affected by primary antibody deficiency. In addition to immunoglobulin treatment, children may need to take antibiotics or antifungal medicines to prevent infections or treat them promptly when they occur. Regular monitoring and check-ups will help to catch infections early. If an autoimmune response occurs, this can be treated with steroid and/or biologic medicines to damp down the immune system so relieving the symptoms.

In some severely affected patients, NEMO deficiency syndrome is treated using a bone marrow or blood stem cell transplant. The aim is to replace the faulty immune system with an immune system from a healthy donor.

Liver transplant has been used in the treatment of this condition.

Timed light exposure can be effective to help people match their circadian rhythms with the expected cycle at their destination; it requires strict adherence to timing. Light therapy is a popular method used by professional athletes to reduce jet lag. Special glasses, usually battery-driven, provide light to the eyes, thus inhibiting the production of melatonin in the brain. Timed correctly, the light may contribute to an advance or delay of the circadian phase to that which will be needed at the destination. The glasses may be used on the plane or even before users leave their departure city.

Timed melatonin administration may be effective in reducing jet lag symptoms. The benefit of using melatonin is likely to be greater for eastward flights than for westward ones because for most people it is easier to delay than to advance the circadian rhythm. There remain issues regarding the appropriate timing of melatonin use in addition to the legality of the substance in certain countries. How effective it may actually be is also questionable. For athletes, anti-doping agencies may prohibit or limit its use.

Timing of exercise and food consumption have also been suggested as remedies, though their applicability in humans and practicality for most travellers are not certain, and no firm guidelines exist. There are very little data supporting the use of diet to adjust to jet lag. While there are data supporting the use of exercise, the intensity of exercise that may be required is significant, and possibly difficult to maintain for non-athletes. These strategies may be used both before departure and after landing. Individuals may differ in their susceptibility to jet lag and in how quickly they can adjust to new sleep-wake schedules.

Short-acting sleep medications can be used to improve sleep quality and timing, and stimulating substances such as caffeine can be used to promote wakefulness, though research results on their success at adapting to jet lag are inconsistent.

For time changes of fewer than three hours, jet lag is unlikely to be a concern, and if travel is for short periods (three days or fewer) retaining a "home schedule" may be better for most people. Sleeping on the plane is only advised if it is within the destination's normal sleep time.

The physical abnormalities resulting from SCS are typically mild and only require a minor surgical procedure or no procedure at all. One of the common symptoms of SCS is the development of short (brachydactyly), webbed fingers and broad toes (syndactyly). These characteristics do not cause any problems to the function of the hands or feet, and thus, no medical procedure is required to fix the abnormalities, unless the patient requests it. Webbing of the fingers may affect the base of the fingers, resulting in delayed hand growth during childhood, but this contributes no functional impairments. Sometimes, individuals with SCS develop broad toes because the bones at the ends of the toes are duplicating themselves. This is especially seen in the big toe, but requires no surgical intervention because it doesn't negatively affect the overall function of the foot. Individuals with these toe abnormalities walk normally and can wear normal footwear.

In more severe cases, frequent surgeries and clinical monitoring are required throughout development. A child born with asymmetrical unilateral coronal synostosis should undergo cranioplasty within its first year of life in order to prevent increased intracranial pressure and to prevent progressive facial asymmetry. Cranioplasty is a surgical procedure to correct prematurely fused cranial bones. The surgery acts to reconstruct and reposition the bones and sutures in order to promote the most normal growth. Cranioplasty is necessary in order to continue to grow and is important for two main reasons. First of all, the skull needs to be able to accommodate the growing brain following childbirth, which it can't because the skull doesn't grow as fast as the brain as long as the sutures remain fused. This results in an increase in pressure surrounding the brain and inhibits the brain from growing, causing the individual to experience significant problems, and if left untreated can eventually lead to death. Secondly, cranioplasty may be required for appearance purposes. This is especially the case in individuals with asymmetrical unilateral coronal synostosis, which requires reconstructive surgery of the face and skull. If cranioplasty is not performed, especially in individuals with unilateral coronal synostosis, then facial asymmetry will get worse and worse over time, which is why cranioplasty should be performed as soon as possible.

Surgery may also be required in individuals with vision problems. Vision problems usually arise due to a lack of space in the eye orbit and skull because of the abnormal bone structure of the face. Decreased space may also lead to abnormal or missing tear ducts and nerve damage. Reconstructive surgery is usually required in order to increase cranial space, correct tear duct stenosis, and/or correct ptosis of the eyelids in order to prevent amblyopia (lazy eye).

Midfacial surgery may also be required during early childhood to correct respiratory problems, dental malocclusion, and swallowing difficulties. A cleft palate is also corrected with surgery, and may involve the use of tympanostomy tubes. If needed, an individual will undergo orthognathic treatment and/or orthodontic treatment after facial development is complete. Since hearing loss is frequently associated with SCS, it is recommended that audiology screening persist throughout childhood.

After cranial reconstructive surgery, a child may be required to wear a molding helmet or some other form of head protection until the cranial bones set into place. This typically takes about three months and depends on the child's age and the severity of the condition. Following recovery, individuals with SCS look and act completely normal, so no one would even be able to tell that they have SCS.

At the hospital, physicians follow standard protocol for managing seizures. Cluster seizures are generally controlled by benzodiazepines such as diazepam, midazolam, lorazepam or clonazepam. The use of oxygen is recommended in the United States, but in Europe it is only recommended in cases of prolonged epileptic status.
