The SPG7 gene, also known as paraplegin, is involved in the progressive genetic disorder known as hereditary spastic paraplegia type 7 (SPG7). This gene provides instructions for making a protein that is part of a complex called the m-AAA protease. The m-AAA protease is found in the mitochondria of cells and is responsible for breaking down proteins that are damaged or no longer needed.

Changes (mutations) in the SPG7 gene can result in a variant of hereditary spastic paraplegia characterized by progressive muscle stiffness (spasticity) and weakness in the legs (paraplegia). This condition may also affect the muscles that control eye movement (ophthalmoplegia). Progressive changes in the SPG7 gene can lead to the development of additional related conditions, including optic atrophy, ataxia, and peripheral neuropathy.

Testing for changes in the SPG7 gene can be helpful in confirming a diagnosis of hereditary spastic paraplegia type 7. Genetic testing may be recommended for individuals with a family history of the condition or for individuals who exhibit symptoms of progressive muscle weakness and stiffness. Testing involves analyzing the DNA sequence of the SPG7 gene to identify any changes or mutations.

References to articles and scientific information about the SPG7 gene and related conditions can be found in external databases such as OMIM, PubMed, and the Seattle Marconi Institute. These resources provide additional information on the genetic characteristics, clinical features, and testing options for hereditary spastic paraplegia type 7.

In addition to genetic testing, other resources available for individuals and families affected by hereditary spastic paraplegia type 7 include support groups, health registries, and catalogs of genetic changes and proteins. These resources can provide valuable information on managing the condition, accessing medical care, and connecting with other individuals and families affected by hereditary spastic paraplegia type 7.

Genetic changes in the SPG7 gene can lead to various health conditions. These changes can affect the proteins produced by the gene, which play a crucial role in the normal functioning of cells. The SPG7 gene is associated with a type of hereditary spastic paraplegia (HSP), known as SPG7-related HSP.

In SPG7-related HSP, there is a progressive weakness and stiffness of the legs (spastic paraplegia) due to degeneration of certain nerve cells in the spinal cord. This condition is characterized by the gradual onset and progression of spasticity, which can lead to difficulty walking and other motor impairments.

Genetic testing can be done to identify changes in the SPG7 gene and confirm a diagnosis of SPG7-related HSP. This testing can be done through various methods, including sequencing the SPG7 gene or analyzing specific regions of the gene for known changes.

The SPG7 gene is listed in various genetic databases and resources, providing additional information on the gene, its variants, and related health conditions. These resources include the Online Mendelian Inheritance in Man (OMIM) database, scientific articles indexed in PubMed, and external genetic testing catalogs.

The SPG7 gene is also known by other names, including paraplegin, MARC1, and NTE-related esterase, and its related health conditions may be referred to by different names in scientific literature.

By referring to these databases and resources, healthcare professionals and researchers can access valuable information on SPG7-related health conditions, including the genetics, clinical features, and potential treatment options. In addition, these resources provide references to scientific articles and studies for further reading and exploration.

It is important to note that genetic changes in the SPG7 gene can result in a spectrum of health conditions, and not all individuals with SPG7-related HSP will experience the same symptoms or disease progression. It is recommended to consult with a healthcare provider or genetic counselor for personalized information and guidance.

Spastic paraplegia type 7

Spastic paraplegia type 7, also known as SPG7, is a genetic condition characterized by progressive spasticity and weakness in the legs (paraplegia). It is caused by mutations in the SPG7 gene.

Spastic paraplegia type 7 is listed as OMIM:607259 in the Online Mendelian Inheritance in Man (OMIM) catalog. Additional information about this condition can be found in scientific articles available through PubMed.

This condition is inherited in an autosomal recessive manner, which means that both copies of the SPG7 gene in each cell have mutations. These mutations result in changes to the paraplegin protein, which is produced from the SPG7 gene.

Common symptoms of spastic paraplegia type 7 include progressive spasticity and weakness in the legs, difficulty walking, and muscle stiffness. Some individuals may also develop additional symptoms such as ophthalmoplegia (weakness or paralysis of the eye muscles).

Genetic testing can be used to confirm a diagnosis of spastic paraplegia type 7. This testing checks for mutations in the SPG7 gene. However, it is important to note that not all mutations in this gene are associated with the condition, and other genetic and environmental factors may influence the development and progression of the disease.

Resources for additional information and support for individuals with spastic paraplegia type 7 and related conditions include the Genetic Testing Registry (GTR), which provides information on available genetic tests and laboratories offering testing services, and the Gene database, which provides information on the SPG7 gene and associated proteins.

Progressive external ophthalmoplegia

Progressive external ophthalmoplegia (PEO) is a genetic disorder characterized by paralysis or weakness of the eye muscles, leading to impaired eye movement. It is often accompanied by additional symptoms such as muscle weakness, spasticity, and changes in muscle tone.

PEO can be caused by mutations in the SPG7 gene, which codes for a protein called paraplegin. This protein is involved in the maintenance of mitochondria, the energy-producing structures within cells. Mutations in the SPG7 gene lead to a dysfunctional paraplegin protein, resulting in mitochondrial abnormalities and impaired energy production.

Diagnosis of PEO involves genetic testing, which can identify mutations in the SPG7 gene. Additional testing may be performed to assess the severity and extent of muscle weakness and spasticity. This can include electromyography (EMG) and nerve conduction studies.

The Online Mendelian Inheritance in Man (OMIM) database provides comprehensive information on the SPG7 gene and its associated conditions. The OMIM entry for the SPG7 gene includes references to scientific articles and resources for further information.

Other genes and proteins listed in the OMIM database are also associated with PEO and related conditions. These include genes encoding other components of the mitochondrial complex, as well as genes involved in various mitochondrial diseases.

The Seattle Structural Genomics Center for Infectious Disease (SSGCID) maintains a catalog of protein structures, including paraplegin. This resource provides information on the structure and function of the protein, which can aid in understanding the molecular basis of PEO.

References to scientific articles on PEO, the SPG7 gene, and related topics can be found in the PubMed database. These articles provide additional information on the genetic basis of PEO, as well as diagnostic and therapeutic approaches.

The Progressive External Ophthalmoplegia Registry and Resource (PEORR) is a centralized database that collects data on patients with PEO and related conditions. This registry serves as a valuable resource for researchers and healthcare providers studying PEO.

In conclusion, progressive external ophthalmoplegia is a genetic disorder characterized by paralysis or weakness of the eye muscles. Mutations in the SPG7 gene, which codes for the paraplegin protein, are a common cause of PEO. Genetic testing, along with additional tests and resources, can aid in the diagnosis and management of this condition.
