Lateral meningocele syndrome (LMS) is a rare genetic disorder characterized by the presence of abnormal outgrowths called meningoceles along the spinal cord. These protrusions occur laterally, or to the side, of the normal neural tube development. LMS is also known by other names, such as lateral body wall defects with congenital heart defects and hemangiomas, or Chen syndrome.

The exact cause of LMS is not yet fully understood, but it is believed to be associated with mutations in certain genes that play a role in neural tube development. One gene in particular, called NOTCH3, has been identified as a potential cause of LMS. NOTCH3 encodes a protein that is involved in cell signaling and the regulation of gene expression. Mutations in this gene can disrupt the normal function of the nervous system and lead to the formation of meningoceles.

LMS follows an autosomal dominant pattern of inheritance, which means that an affected individual has a 50% chance of passing the mutated gene to each of their children. However, LMS is considered a rare disorder, and its frequency in the general population is unknown.

Diagnosis of LMS is typically made based on the presence of characteristic symptoms and imaging studies that confirm the presence of meningoceles. Genetic testing may also be conducted to identify mutations in specific genes associated with LMS. Additional information and support can be found through scientific articles, advocacy organizations, and genetic counseling services. OMIM (Online Mendelian Inheritance in Man) and PubMed are valuable resources for learning more about LMS and related disorders.

In conclusion, lateral meningocele syndrome is a rare genetic disorder characterized by abnormal protrusions called meningoceles along the spinal cord. It is associated with mutations in genes that play a role in neural tube development, particularly the NOTCH3 gene. The disease follows an autosomal dominant pattern of inheritance and can be diagnosed through imaging studies and genetic testing. For more information and support, individuals can turn to scientific articles, advocacy organizations, and genetic counseling services.

Frequency

In the context of Lateral meningocele syndrome, the frequency of the condition is currently unknown. The Online Mendelian Inheritance in Man (OMIM) database provides information on the frequency of genetic disorders, but no data on the frequency of this specific syndrome is available.

What makes healthcare so expensive in America? Rather than mere overuse of medical services, a study published in the Journal of the American Medical Association found that the high cost of medical treatments and procedures is what makes healthcare expenditures twice as costly in the U.S. than in other wealthy countries, The Washington Post

Due to the rarity of the condition, testing centers and genetic databases may not have specific genes listed for meningocele or catalog the names associated with this condition. However, additional information about the frequency of cases and advocacy on the causes of Lateral meningocele syndrome can be found through patient advocacy groups and rare diseases organizations.

Chen et al. (2005) reported a patient with Lateral meningocele syndrome and suggested an autosomal dominant pattern of inheritance. The exact frequency of this syndrome in the general population remains unknown.

More scientific articles associated with Lateral meningocele syndrome can be found on PubMed, which is a resource for scientific and genetic research. The genes involved in this condition, such as NOTCH3, can be further explored through scientific papers and genetic studies.

Given the rarity of Lateral meningocele syndrome, more information on its frequency and associated genes can be obtained through further research and collaboration among scientists and medical professionals.

Causes

Lateral meningocele syndrome is a rare genetic condition characterized by the presence of lateral meningoceles, which are protrusions of the meninges through openings in the spine. The exact cause of the syndrome is not yet fully understood, but it is believed to be associated with mutations in the NOTCH3 gene.

The NOTCH3 gene provides instructions for making a protein that is essential for the normal development and function of blood vessels. Mutations in this gene can disrupt the normal signaling pathway and lead to the formation of abnormal blood vessels. These abnormal blood vessels may contribute to the development of the protrusions seen in lateral meningocele syndrome.

Lateral meningocele syndrome is inherited in an autosomal dominant pattern, which means that a mutation in only one copy of the gene is sufficient to cause the condition. In some cases, the syndrome may result from new mutations in the gene and occur in individuals with no family history of the condition.

Additional research is needed to fully understand the underlying causes and mechanisms of lateral meningocele syndrome.

  • Neurocutaneous syndrome with lateral meningocele
  • Autosomal dominant lateral meningocele syndrome

Lateral meningocele syndrome, also known as Chen syndrome or LMNS, is a rare genetic condition characterized by the presence of lateral meningoceles and additional symptoms. The condition was first described by Chen in 1986.

A lateral meningocele is a rare protrusion of the meninges through a defect in the lateral body wall. These protrusions are usually located in the lower back or pelvis. In some cases, individuals with lateral meningocele syndrome may have multiple meningoceles.

Individuals with lateral meningocele syndrome may also present with other symptoms, such as skeletal abnormalities, such as scoliosis or fusion of the vertebrae; cardiovascular anomalies; genitourinary malformations; and neurological deficits.

Lateral meningocele syndrome is caused by mutations in the NOTCH3 gene. This gene is responsible for encoding a protein involved in cell signaling and the formation of blood vessels. Mutations in this gene can result in impaired blood vessel function and abnormalities in the development of various organs and systems.

The inheritance pattern of lateral meningocele syndrome is autosomal dominant, meaning that an affected individual has a 50% chance of passing the condition on to each of their children. Genetic testing is available to confirm a diagnosis of lateral meningocele syndrome and identify the specific mutation in the NOTCH3 gene.

As lateral meningocele syndrome is a rare condition, there is limited information and resources available for affected individuals and their families.
