Marinesco-Sjögren syndrome

Marinesco-Sjögren syndrome is a rare genetic condition that affects the eyes, muscles, and other systems of the body. It is also known as Marinesco-Sjögren syndrome which is named after the French pediatrician, Jules Marinesco, and the Swedish ophthalmologist, Gunnar Sjögren. This condition is included in the OMIM catalog of genetic diseases and is associated with mutations in certain genes.

Patients with Marinesco-Sjögren syndrome typically present with a triad of symptoms including cerebellar ataxia (problems with coordination and balance), congenital cataracts (clouding of the lens in the eye since birth), and muscle weakness (myopathy). Although these symptoms are commonly seen, there can be variation between patients in the severity and combination of symptoms.

The inheritance pattern of Marinesco-Sjögren syndrome is still not well understood. It is thought to be inherited in an autosomal recessive manner, which means that both copies of the affected gene must be mutated to develop the condition. Genetic testing is available for diagnosis and can help confirm the presence of mutations in the associated genes. This can be useful for genetic counseling and family planning.

There is currently no specific treatment for Marinesco-Sjögren syndrome. Treatment is primarily focused on managing the symptoms and providing support to the patient. Physical therapy and assistive devices may be recommended to help with muscle weakness and difficulties with movement. Regular eye exams and early intervention for cataracts can help preserve vision. Additional research is needed to better understand the causes and possible treatment options for this rare condition.

For more information about Marinesco-Sjögren syndrome, you can visit the Genetic and Rare Diseases Information Center (GARD), OMIM catalog, or contact advocacy organizations such as the Marinesco-Sjögren Syndrome Foundation. Scientific articles and references can also be found on PubMed. These resources provide valuable information about the condition, its associated genes and proteins, frequency, inheritance, and other related diseases.

Frequency

The Marinesco-Sjögren syndrome is a rare genetic condition that is characterized by the combination of cerebellar ataxia, congenital cataracts, progressive muscle weakness (myopathy), and intellectual disability.

The frequency of the Marinesco-Sjögren syndrome is unknown. It is a rare condition and the exact number of affected individuals is difficult to determine.

According to a study by Zerres et al., the prevalence of Marinesco-Sjögren syndrome is estimated to be 1 in 600,000 individuals in the general population. However, this estimate may not be accurate due to the rarity of the condition and the limited number of reported cases.

The Marinesco-Sjögren syndrome is inherited in an autosomal recessive manner, which means that individuals with the syndrome inherit two copies of the mutated gene, one from each parent. The syndrome is caused by mutations in the SIL1 gene, which provides instructions for making a protein involved in the proper folding and processing of other proteins in the body.

Genetic testing can be performed to confirm a diagnosis of Marinesco-Sjögren syndrome. This testing can identify mutations in the SIL1 gene that are associated with the syndrome. The Center for Human Genetics offers genetic testing for Marinesco-Sjögren syndrome, and additional information about testing can be found in the OMIM catalog and on the OMIM website (Online Mendelian Inheritance in Man).

Patient support resources and advocacy organizations can provide more information about the Marinesco-Sjögren syndrome. Resources such as PubMed and Genetests can also provide scientific articles and references on the syndrome and related rare diseases.

In conclusion, the frequency of Marinesco-Sjögren syndrome is rare, and it is estimated to affect about 1 in 600,000 individuals in the general population. Genetic testing can be performed to confirm a diagnosis, and patient support resources and advocacy organizations are available to provide additional information and support for individuals with this condition.

Causes

The exact cause of Marinesco-Sjögren syndrome is unknown. However, it is believed to be a rare genetic condition that is inherited in an autosomal recessive pattern, meaning that both parents must carry a faulty gene for the condition to occur in their child.

There are several genes that have been associated with Marinesco-Sjögren syndrome, including SIL1, BAG3, and HSP27. These genes provide instructions for making proteins that are involved in various cellular processes.

When these genes are mutated, they can lead to abnormal protein function and cause problems with the development and function of different tissues and organs in the body. In the case of Marinesco-Sjögren syndrome, the mutation affects the brain, eyes, and muscles, resulting in the characteristic symptoms of the condition.

It is important to note that not all cases of Marinesco-Sjögren syndrome are caused by mutations in these known genes, suggesting that there may be additional genetic factors involved in the condition.

Testing for Marinesco-Sjögren syndrome can be done through genetic testing, which can help confirm the diagnosis and identify specific mutations in the genes associated with the condition.

Learn more about the gene associated with Marinesco-Sjögren syndrome

Marinesco-Sjögren syndrome is a rare genetic condition that primarily affects the muscles and eyes. It is associated with mutations in the SIL1 gene, which plays a role in protein folding and transport within cells.

Marinesco-Sjögren syndrome is inherited in an autosomal recessive pattern, which means that both copies of the SIL1 gene must have mutations for the condition to be present. The syndrome is named after two physicians, Dr. Gheorghe Marinescu and Dr. Torsten Sjögren, who first described the condition in the early 20th century.

Individuals with Marinesco-Sjögren syndrome often experience muscle weakness and wasting (myopathy), impaired coordination and balance, intellectual disability, and delayed development. The syndrome can also cause visual impairment and problems with the structure and function of the eyes, such as cataracts, nystagmus, and ptosis.

Inheritance

The Marinesco-Sjögren syndrome is inherited in an autosomal recessive manner. This means that a person must inherit two copies of the mutated gene, one from each parent, in order to develop the syndrome.

The specific gene associated with the syndrome is called SIL1, and mutations in this gene have been found to be responsible for most cases of Marinesco-Sjögren syndrome. Other rare causes of the syndrome have also been reported, but these are not as well characterized.

Marinesco-Sjögren syndrome is listed in the Online Mendelian Inheritance in Man (OMIM) catalog, a comprehensive database of genetic diseases and their associated genes. More information about the genetics of Marinesco-Sjögren syndrome can be found in the OMIM entry for the condition (OMIM 248800).
