Hypermanganesemia with dystonia is a rare genetic condition that causes problems with movement and muscle contractions. It is associated with an excess of manganese in the body. Hypermanganesemia with dystonia is caused by mutations in the SLC39A14 gene, which builds a protein that helps regulate the levels of manganese in the body.
Individuals with hypermanganesemia with dystonia may experience muscle contractions and neurological problems, such as dystonia, a condition characterized by involuntary muscle contractions. The frequency and severity of symptoms can vary from patient to patient.
Hypermanganesemia with dystonia is inherited in an autosomal recessive manner, which means that both parents must carry a mutated copy of the SLC39A14 gene for their child to be affected. Genetic testing can be used to confirm a diagnosis of hypermanganesemia with dystonia.
Additional resources for information, support, and advocacy on hypermanganesemia with dystonia include scientific articles and research papers available on PubMed, OMIM catalog which provides information about genes and genetic diseases, and the resources provided by advocacy centers like the Clayton Dabney Foundation and the Dystonia Medical Research Foundation.
Frequency
The frequency of hypermanganesemia with dystonia is not well established. It is considered a rare condition that is associated with excessive accumulation of manganese in the central nervous system.
Hypermanganesemia with dystonia can be caused by mutations in the SLC39A14 gene. Mutations in this gene result in impaired manganese transport, leading to the build-up of manganese in the brain.
Each patient with hypermanganesemia with dystonia may have mutations in different genes. Additional genes that have been associated with this condition include SLC30A10, SLC39A8, and SLC39A14.
The frequency of each specific genetic mutation in hypermanganesemia with dystonia is not well characterized. However, some studies have reported certain mutations to be more common than others. For example, the p.Thr12Met mutation in the SLC39A14 gene has been found in several patients with hypermanganesemia with dystonia.

Causes
The main cause of hypermanganesemia with dystonia is a genetic mutation. These mutations affect genes that are involved in the regulation of manganese levels in the body. When these genes are mutated, they can lead to an excess of manganese in the body, which can cause neurological problems and movement disorders.
One of the genes associated with hypermanganesemia is SLC39A14. Mutations in this gene can result in the accumulation of manganese in the liver and other tissues, leading to the symptoms of the condition. This gene is inherited in an autosomal recessive manner, meaning that both parents must carry a mutation in order for their child to develop the condition.
There are also some other genes that have been associated with hypermanganesemia. These include SLC30A10 and SLC39A8. Mutations in these genes can also lead to the accumulation of manganese in the body and the development of neurological problems and movement disorders.
Exposure to excess manganese in the environment can also cause hypermanganesemia. This is more commonly seen in occupational settings, where workers are exposed to high levels of manganese. In these cases, the condition is referred to as “manganese-induced parkinsonism”.
It is important to note that hypermanganesemia is a rare condition, and its exact causes are still being studied. Currently, there is no cure for hypermanganesemia, but there are treatments available to help manage the symptoms of the condition.

Learn more about the genes associated with Hypermanganesemia with dystonia
Hypermanganesemia with dystonia is a rare condition characterized by excess manganese in the body, which leads to neurological problems such as dystonia, abnormal muscle contractions, and movement disorders. This condition is also known as manganese-induced dystonia.
The genetic cause of hypermanganesemia with dystonia is associated with mutations in the SLC39A14 gene. This gene provides instructions for making a protein that is involved in the transport of manganese into cells. Mutations in the SLC39A14 gene impair the normal function of this protein, resulting in the accumulation of manganese in the body.
Hypermanganesemia with dystonia follows an autosomal recessive inheritance pattern, which means that individuals with two copies of the mutated gene (one inherited from each parent) are affected. In some cases, this condition can also be caused by abnormalities in other genes.
There are currently limited resources and scientific articles available specifically on hypermanganesemia with dystonia. However, there are scientific articles and resources available on related topics such as manganese toxicity, dystonia, and genetic testing for movement disorders.
For more information about hypermanganesemia with dystonia, you can refer to the following resources:

It is important to note that hypermanganesemia with dystonia is a rare condition, and more scientific research and resources are needed to better understand and support individuals affected by this condition.
Inheritance
The inheritance pattern of hypermanganesemia with dystonia is autosomal recessive. This means that both copies of the gene responsible for the condition must have mutations in order for the disease to occur. If a person has one mutated copy of the gene and one normal copy, they will be a carrier of the condition but will not have any symptoms.
The condition is caused by mutations in the SLC39A14 gene. This gene provides instructions for making a protein that is involved in the transport of manganese into cells. In hypermanganesemia with dystonia, mutations in this gene result in the buildup of excess manganese in the body, particularly in the brain and liver.
Hypermanganesemia with dystonia is a rare genetic condition, with only a few dozen cases reported in the scientific literature. It is estimated to occur in about 1 in every 1 million individuals. The condition was first described in 2002 by Clayton et al. in a publication in the journal Neurology.
Additional information about the genetics of hypermanganesemia with dystonia can be found in the OMIM catalog, which provides information on genetic diseases and associated genes. The OMIM entry for hypermanganesemia with dystonia is 613280.
Genetic testing can be done to confirm a diagnosis of hypermanganesemia with dystonia. This involves analyzing the SLC39A14 gene for mutations. Testing can be arranged through a genetics center or other healthcare provider that specializes in genetic conditions. It is important to note that not all mutations in the SLC39A14 gene will cause hypermanganesemia with dystonia, and some individuals with the condition may not have mutations in this gene.
For individuals with hypermanganesemia with dystonia and their families, support and advocacy resources are available. These resources can provide information about the condition, connect patients with other individuals and families affected by the condition, and offer support in managing the challenges associated with the disease.

Genetic Testing Information
Genetic testing can provide valuable information about the underlying causes of hypermanganesemia with dystonia. As this condition is rare, genetic testing is an important tool for diagnosis and can help guide treatment decisions.
There are several genes associated with hypermanganesemia. Mutations in the SLC39A14 gene are the most common cause of this condition. Other genes, such as SLC30A10 and SLC39A8, have also been implicated in rare cases.
To date, more than 20 mutations in the SLC39A14 gene have been identified in patients with hypermanganesemia. These mutations lead to a build-up of manganese in the body, affecting the central nervous system and causing movement problems.
Genetic testing can help identify these specific mutations in the SLC39A14 gene and other associated genes. It can also determine the inheritance pattern of the condition, which can be autosomal recessive or dominant depending on the specific gene involved.
There are several resources available for genetic testing and support. The Genetic and Rare Diseases Information Center (GARD) provides information on different genetic testing options and connects patients with relevant advocacy groups. GARD also offers articles and additional information about hypermanganesemia and related diseases.
The Online Mendelian Inheritance in Man (OMIM) catalog is another useful resource for genetic testing information. It provides a comprehensive database of genetic disorders, including hypermanganesemia, and lists the associated genes and their specific mutations.
