Myopathy with deficiency of iron-sulfur cluster assembly enzyme, also known as ISCU myopathy, is a rare genetic condition associated with a deficiency of the enzyme iron-sulfur cluster assembly enzyme (ISCU). This deficiency leads to muscle weakness and other symptoms in affected individuals.

ISCU myopathy has an autosomal recessive inheritance pattern, meaning that individuals must inherit two copies of the mutated gene – one from each parent – in order to develop the condition. The ISCU gene is responsible for providing instructions for the production of the ISCU enzyme, which plays a crucial role in the assembly of iron-sulfur clusters within cells.

The main symptoms of ISCU myopathy include muscle weakness, difficulty walking, and muscle pain. Additional symptoms may include abnormalities in the heart, kidneys, and other tissues. The severity of the symptoms can vary among individuals. Some patients may have normal muscle strength, while others may have significant muscle weakness.

Diagnosis of ISCU myopathy is typically made through genetic testing, which can detect mutations in the ISCU gene. Additional testing may be done to rule out other genetic causes of muscle diseases. It is important for individuals with ISCU myopathy to seek genetic counseling and testing for their family members, as this condition can be inherited.

There is currently no cure for ISCU myopathy, but treatment options are available to help manage the symptoms. Physical therapy and exercise can help improve muscle strength and function. Other supportive treatments may include medication to manage pain and complications associated with the condition.

For more information about ISCU myopathy, its causes, and available resources, please visit scientific websites such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources provide additional articles and information to support patients and their families. Advocacy organizations and genetic support groups can also offer valuable support and information.

The last 20 years have seen the cost of medical care increase about 70% faster than the rate of general inflation as measured by the Consumer Price Index (CPI), the Research Division of the Federal Reserve Bank of St. Louis Healthcare inflation dropped to a historical low after 2010 but is again on the rise as of 2018, according to Bloomberg.

Frequency

Myopathy with deficiency of iron-sulfur cluster assembly enzyme is a rare condition that has been reported in a limited number of individuals. This suggests that the frequency of this condition is low.

The genetic cause of this condition is associated with mutations in the ISCU gene, which is involved in the assembly of iron-sulfur clusters within cells. These clusters are important for the function of many enzymes, including aconitase and succinate dehydrogenase.

The inheritance of myopathy with deficiency of iron-sulfur cluster assembly enzyme is autosomal recessive, which means that an affected individual must inherit two copies of the mutated gene – one from each parent. Individuals who only have one copy of the mutated gene are carriers and do not typically show symptoms of the condition.

Since this condition is rare, there may be limited awareness and resources available for patients and their families. However, advocacy groups and genetic testing companies may provide additional support and information about this condition.

For more information about the frequency of myopathy with deficiency of iron-sulfur cluster assembly enzyme, you can refer to scientific articles and resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources provide detailed information about the genes, inheritance patterns, and frequencies of various genetic diseases.

Causes

The myopathy with deficiency of iron-sulfur cluster assembly enzyme is caused by mutations in the ISCU gene. Iron-sulfur clusters are important for the normal functioning of cells and tissues. The ISCU gene encodes a protein involved in the assembly of iron-sulfur clusters within the cell.

Mutations in the ISCU gene can lead to a deficiency in the assembly of iron-sulfur clusters. This deficiency affects various tissues and can cause muscle weakness and myopathy in affected individuals.

The condition is inherited in an autosomal recessive manner, meaning that individuals need to inherit two copies of the mutated gene (one from each parent) in order to develop the condition.

Research on the myopathy with deficiency of iron-sulfur cluster assembly enzyme and the ISCU gene is ongoing. Scientists are learning more about the specific mechanisms underlying this condition and how the deficiency in iron-sulfur cluster assembly affects the normal functioning of cells and tissues.

For more information about the causes of this condition, you can refer to the following resources and references:

• OMIM: a catalog of human genes and genetic disorders. You can search for the ISCU gene and learn more about the condition.
• PubMed: a database of scientific articles. You can search for publications related to the myopathy with deficiency of iron-sulfur cluster assembly enzyme.
• Genetic testing: Genetic testing can be performed to identify mutations in the ISCU gene and confirm the diagnosis.
• Advocacy and support: There are various advocacy and support organizations that provide resources and support for individuals and families affected by this condition.

It is important to consult with a healthcare professional for a proper diagnosis and to learn more about the specific causes and treatment options for the myopathy with deficiency of iron-sulfur cluster assembly enzyme.

Learn more about the gene associated with Myopathy with deficiency of iron-sulfur cluster assembly enzyme

Myopathy with deficiency of iron-sulfur cluster assembly enzyme (ISCU) is a genetic condition that affects the muscle tissue. It is caused by a deficiency of the ISCU enzyme, which is responsible for the assembly of iron-sulfur clusters within cells. This enzyme is essential for the normal function of muscles, as well as other tissues such as the heart, kidneys, and brain.

The ISCU gene, also known as the iron-sulfur cluster scaffold homolog (ISCU), is located on chromosome 12. Mutations in this gene can lead to a deficiency of the ISCU enzyme, causing the symptoms associated with myopathy with deficiency of iron-sulfur cluster assembly enzyme.

This condition has an autosomal recessive inheritance pattern, which means that both copies of the ISCU gene must have mutations in order for the condition to be present. If only one copy of the gene is mutated, the individual will be a carrier of the condition but will not experience any symptoms.

To learn more about the ISCU gene and the myopathy with deficiency of iron-sulfur cluster assembly enzyme, you can visit the following resources:

1. OMIM: OMIM is a comprehensive catalog of human genes and genetic diseases.
