Encephalocraniocutaneous lipomatosis (ECCL) is a very rare genetic condition that affects multiple parts of the body, including the brain, skull, and skin. It is also known as Haberland syndrome, after the German neurologist Hans Haberland, who first described it in 1970.

ECCL is characterized by the presence of fatty growths in the brain (encephalo-), skull (crani-), and skin (-cutaneous). These growths can vary in size and location, and can cause various health problems, depending on their location. The condition is also often associated with abnormalities or malformations of the eyes and spinal cord.

The exact cause of ECCL is currently unknown, but it is believed to be a genetic condition. Research has identified mutations in two genes, FGFR1 and KLLN, that are associated with the development of ECCL. Mutations in these genes disrupt normal development and can lead to the formation of fatty growths.

Due to its rarity, there is still much to learn about ECCL. The Online Mendelian Inheritance in Man (OMIM) database is a valuable resource for finding more information about this condition. Additionally, there are support and advocacy organizations, such as the Encephalocraniocutaneous (ECCL) Lipomatosis Support Center, that provide information, resources, and support to patients and their families.

In conclusion, encephalocraniocutaneous lipomatosis is a rare genetic condition with fatty growths in the brain, skull, and skin. Its exact causes are still being researched, and more information about this condition can be found in scientific articles and genetic testing resources.

Frequency

This condition is very rare. The frequency of encephalocraniocutaneous lipomatosis is not well-established. According to the Genetics Home Reference, the condition is estimated to affect fewer than 1 in 1,000,000 people worldwide. However, this frequency may be underestimated due to a lack of awareness and limited scientific studies on the condition.

Americans see their primary care doctors less often than they did a decade ago. Adults under 65 made nearly 25% fewer visits to primary care providers in 2016 than they did in 2018, according to National Public Radio. In the same time period, the number of adults who went at least a year without visiting a primary care provider increased from 38% to 46%.

Encephalocraniocutaneous lipomatosis is not listed in popular genetic testing resources like OMIM, which further contributes to the lack of information and understanding about the condition.

While the exact cause of this condition is unknown, it is believed to be caused by genetic changes in a specific gene. A gene called the FGFR1 gene has been associated with encephalocraniocutaneous lipomatosis in some rare cases. However, it is important to note that not all individuals with the condition have changes in this gene, suggesting that there may be other possible genes or genetic factors involved.

Due to the rarity of the condition, there is limited scientific research and information available. However, there are advocacy groups and support centers that provide additional resources and support for patients and their families. These organizations can provide more information about the condition, possible gene mutations, and available testing options.

In conclusion, encephalocraniocutaneous lipomatosis is a rare condition with an unknown frequency. More scientific research and genetic testing are needed to better understand the genetic causes and inheritance patterns of this condition.

Causes

Encephalocraniocutaneous lipomatosis (ECCL) is a genetic condition caused by changes (mutations) in a gene called BRAF. This gene provides instructions for making a protein that is involved in cell growth and division. Mutations in the BRAF gene can lead to the development of growths in various parts of the body, including the brain, skull, and skin.

ECCL is a rare disease, and its frequency is currently unknown. It is thought to occur more frequently in individuals of Portuguese descent.

The inheritance pattern of ECCL is not well understood. Most cases occur sporadically, meaning they occur in people with no history of the condition in their family. However, a few families with multiple affected members have been reported, suggesting that in some cases, the condition may be inherited in an autosomal dominant manner.

The exact cause of ECCL is still unknown. It is believed to be a multifactorial disorder, which means that multiple genetic and environmental factors likely contribute to its development.

Additional research is needed to learn more about the genetic and environmental factors that may be involved in the development of ECCL.

Learn more about the gene associated with Encephalocraniocutaneous lipomatosis

Encephalocraniocutaneous lipomatosis (ECCL) is a rare genetic condition characterized by the presence of fatty tumors on the head and face, abnormalities of the brain and skull, and pigmented skin anomalies. This condition is caused by mutations in the FGFR1 gene.

The FGFR1 gene provides instructions for making a protein called fibroblast growth factor receptor 1. This protein is important for normal development and function of the brain, skull, and skin. Mutations in the FGFR1 gene can disrupt the normal function of the protein, leading to the development of the characteristic features of ECCL.

There are two types of ECCL, known as ECCL type 1 and ECCL type 2. The two types have similar signs and symptoms, but they are caused by different mutations in the FGFR1 gene.

The exact frequency of ECCL is unknown, but it is considered a rare condition. It has been reported in fewer than 100 individuals worldwide. ECCL affects males and females equally and is present at birth.

If you or someone you know has been diagnosed with ECCL, it is important to seek support and resources. There are advocacy organizations and patient support groups that can provide additional information and connect you with other individuals and families affected by this condition.

Inheritance

Encephalocraniocutaneous lipomatosis (ECCL), also known as Haberland syndrome, is a rare genetic disorder. The exact cause of ECCL is still unknown, but it is believed to be caused by a mutation in the FGFR1 or FGFR2 gene. These genes provide instructions for making proteins that are involved in the development and maintenance of the nervous system, skin, and skeletal system.

ECCL is thought to be inherited in an autosomal dominant manner, which means that an affected person has a 50% chance of passing the condition on to their children. However, the majority of cases of ECCL occur sporadically, without any family history of the condition.

Genetic testing for mutations in the FGFR1 and FGFR2 genes can be used to confirm a diagnosis of ECCL. This testing is usually done when a patient has characteristic symptoms of the condition, such as skin growths, abnormalities of the central nervous system, and characteristic facial features.

It is important for individuals with ECCL to receive appropriate medical care and support. The treatment of ECCL focuses on managing the symptoms of the condition, such as skin growths and central nervous system abnormalities. Regular monitoring by a medical team with expertise in ECCL is recommended to ensure the best possible outcomes.

For more information about ECCL, its inheritance, and management, it is recommended to consult with medical experts, support organizations, and advocacy groups. Resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed can provide additional scientific articles and references about ECCL and related conditions.

Genetic Testing Information

In the case of encephalocraniocutaneous lipomatosis (ECCL), a rare condition with growths on the head, eyes, and skin, genetic testing can provide important information about the underlying causes and inheritance of the condition.

Genetic testing for ECCL typically involves analyzing a patient’s DNA for mutations in specific genes. The most common gene associated with ECCL is the FGFR2 gene, although mutations in other genes have also been identified in some cases.

Testing is usually performed by a specialized center or laboratory that focuses on genetic testing for rare diseases. The specific testing method used may vary, but it often involves sequencing the patient’s DNA and comparing it to a catalog of known genetic variants associated with ECCL.

If a mutation is identified, it can provide valuable information about the inheritance pattern of the condition. In some cases, ECCL is inherited in an autosomal dominant manner, which means that a person only needs to inherit one copy of the mutated gene to develop the condition. However, in other cases, ECCL is caused by de novo mutations, which occur spontaneously and are not passed down from parents.

Genetic testing can also help to differentiate ECCL from other conditions that may have similar symptoms. For example, ECCL can cause the growth of benign tumors called lipomas, but these growths can also occur without the presence of ECCL. Genetic testing can help to confirm the diagnosis and rule out other possible causes of the lipomas.

In addition to providing information about the genetic basis of ECCL, genetic testing can also guide treatment decisions and provide valuable information for patient counseling and support. Patients and their families may benefit from learning more about the condition, its possible causes, and the available treatment options.

For more information about genetic testing for ECCL, as well as additional resources and support, patients and healthcare providers can consult scientific articles, genetic testing centers, online databases such as OMIM or PubMed, and advocacy organizations focused on rare diseases.
