The MT-ND4L gene is a part of the catalog of human genes and genetic disorders. It also goes by the names NADH-ubiquinone oxidoreductase chain 4L and NADH dehydrogenase subunit 4L. This gene is related to the optic nerve and optic cells. According to OMIM, a registry of human genes and genetic conditions, mutations in the MT-ND4L gene are associated with Leber hereditary optic neuropathy, a genetic disorder that causes vision loss.

The MT-ND4L gene provides instructions for making a protein that is a part of NADH dehydrogenase, one of the enzyme complexes in mitochondria, the energy-producing structures within cells. Changes in this gene can lead to the deficiency in the activity of NADH dehydrogenase, which affects the mitochondria’s ability to generate energy. Deficiency in the function of this enzyme complex can result in mitochondrial diseases and neuropathy, among other conditions.

Various databases and scientific resources, such as PubMed and the SeattleSNPs, provide additional information on the MT-ND4L gene. These resources can be used for genetic testing, finding more information, and researching related articles and references on mitochondrial diseases and genetic changes in the MT-ND4L gene.

Genetic changes in the MT-ND4L gene can lead to various health conditions, particularly those related to mitochondrial dysfunction. Mitochondria are responsible for producing energy within cells. Mutations in the MT-ND4L gene can affect the function of the NADH-ubiquinone oxidoreductase complex, also known as Complex I, which is involved in the production of ATP.

One well-known condition associated with MT-ND4L gene mutations is Leber hereditary optic neuropathy (LHON). LHON is characterized by a sudden loss of central vision due to the death of cells in the optic nerve. Mutations in the MT-ND4L gene can impair Complex I function in the optic nerve, leading to this vision loss.

Further information on health conditions related to genetic changes in the MT-ND4L gene can be found through various resources such as PubMed, Seattle Children’s Hospital, and the Online Mendelian Inheritance in Man (OMIM) database. These resources provide additional scientific articles, genetic testing information, and other resources for diseases related to mitochondrial deficiency and Complex I dysfunction.

Pre-tax flexible spending accounts (FSAs) are often touted as the answer to high out-of-pocket medical costs, but many FSAs have “use it or lose it” rules. FSA holders lose $50 to $100 per year on average, CBS News reported, but since you’re allowed to contribute up to $2,650, you could risk losing thousands of dollars if you don’t spend your FSA money in time.

The OMIM database provides a catalog of gene names, genetic disorders, and associated genes. It also lists references to scientific articles and other sources of information on these conditions. Genetic testing can be performed to identify mutations in the MT-ND4L gene and to provide further information on the specific variant.

In addition to LHON, other health conditions associated with MT-ND4L gene mutations include optic atrophy, hereditary motor and sensory neuropathy, and other mitochondrial disorders. The exact impact of these genetic changes on health may vary depending on the specific mutation and other factors.

In conclusion, genetic changes in the MT-ND4L gene can result in various health conditions, particularly those related to mitochondrial dysfunction. Resources such as PubMed, Seattle Children’s Hospital, and the OMIM database can provide additional information on these conditions, including genetic testing options and scientific articles.

Leber hereditary optic neuropathy

Leber hereditary optic neuropathy (LHON) is a hereditary optic neuropathy caused by mutations in the MT-ND4L gene. It is also known by other names such as Leber optic atrophy, Leber’s disease, and Leber’s optic neuropathy.

LHON is a complex disease that leads to a deficiency in the NADH dehydrogenase subunit 4L (ND4L) enzyme. This deficiency affects the function of mitochondrially encoded NADH dehydrogenase complexes and leads to the degeneration of optic nerve cells.

The hereditary nature of LHON means that it can be passed down through families. It is primarily caused by mutations in the MT-ND4L gene.

There are various resources available for genetic testing and additional information on LHON. The OMIM database provides catalog information on the gene, including variant and disease-related information. The GeneTests and Genetic Testing Registry provide information on available genetic tests for LHON and other mitochondrial diseases.

Overall, the MT-ND4L gene plays a crucial role in the function of mitochondria and the health of optic nerve cells. Understanding the genetic and molecular mechanisms underlying LHON can provide insights into potential therapeutic strategies for this condition.

Mitochondrial complex I deficiency

Mitochondrial complex I deficiency is a genetic disease characterized by a malfunction in the NADH:ubiquinone oxidoreductase enzyme complex, also known as complex I. This complex plays a key role in the electron transport chain, which is essential for generating energy in the form of ATP.

This deficiency can lead to a range of conditions, including optic neuropathy, leber hereditary optic neuropathy, and other optic diseases. It can also be associated with various other diseases and syndromes.

To diagnose mitochondrial complex I deficiency, additional tests such as NADH tetrazolium reductase (NADH-TR) staining and enzyme activity assays are performed. Genetic testing can also provide information on specific gene mutations related to complex I deficiency.

There are several genes involved in the production of complex I, including the MT-ND4L gene. Mutations in these genes can disrupt the normal function of complex I, leading to deficiency and associated health conditions.

Scientific databases and resources, such as PubMed, OMIM, and genetic testing databases, provide information on the genes and mutations related to mitochondrial complex I deficiency. This information can help researchers and healthcare professionals better understand the disease and develop effective diagnostic and treatment strategies.

References to related articles and scientific publications can be found in these databases, as well as in the scientific literature. The Mitochondrial Disease Registry is also a valuable resource for information on mitochondrial complex I deficiency and other mitochondrial diseases.

In summary, mitochondrial complex I deficiency is a genetic disorder that affects the function of complex I, leading to a range of health conditions. Genetic testing and scientific databases provide essential information on the genes and mutations associated with this deficiency, aiding in diagnosis and treatment efforts.
