Léri-Weill dyschondrosteosis

Léri-Weill dyschondrosteosis is a rare genetic condition associated with skeletal abnormalities, primarily affecting the growth plates in the long bones of the arms. It is also known as dyschondrosteosis and is characterized by short stature, particularly in the arms and legs, along with certain distinctive skeletal features.

The condition is caused by mutations in the SHOX gene, located on the X and Y chromosomes. These mutations lead to abnormal skeletal development, resulting in the characteristic signs and symptoms of Léri-Weill dyschondrosteosis.

Most cases of Léri-Weill dyschondrosteosis are inherited in an autosomal dominant manner, which means that an affected individual has a 50% chance of passing the condition on to their children. However, in some cases, the condition can occur sporadically, without a family history.

Diagnosing Léri-Weill dyschondrosteosis typically involves a physical examination, evaluation of the patient’s medical history, and genetic testing to confirm the presence of mutations in the SHOX gene. Additional imaging studies, such as X-rays, may be used to evaluate skeletal abnormalities.

Treatment for Léri-Weill dyschondrosteosis focuses on managing the symptoms and improving quality of life. This may include growth hormone therapy to help promote growth, orthopedic interventions to correct skeletal abnormalities, and ongoing monitoring for associated health issues.

While Léri-Weill dyschondrosteosis is a rare condition, there are resources available for support and advocacy. The Léri-Weill Dyschondrosteosis Foundation provides free information and resources for patients, families, and healthcare professionals. Scientific articles, clinician guides, and references can also be found on PubMed and OMIM, which are reputable sources for scientific literature and genetic information.

Frequency

Léri-Weill dyschondrosteosis is an idiopathic skeletal dysplasia, and it is considered to be the most common form of mesomelic dysplasia. However, it is still a relatively rare condition. According to the Léri-Weill Dyschondrosteosis Catalog, the prevalence of this condition is estimated to be 1 in 100,000 individuals.

The condition is named after Dr. Pierre Léri and Dr. Maurice Weill, who first described it in 1929. Léri-Weill dyschondrosteosis is often referred to as LWD or Léri-Weill syndrome.

The symptoms of Léri-Weill dyschondrosteosis are caused by a genetic mutation in the SHOX gene, which is located on the X and Y chromosomes. This gene plays a crucial role in the development of the skeleton, especially in the growth of the long bones in the arms and legs.

Léri-Weill dyschondrosteosis is most commonly found in females, as it has an X-linked dominant inheritance pattern. However, males can also be affected, typically in a milder form.

Diagnosis of Léri-Weill dyschondrosteosis is usually based on clinical evaluation and radiographic imaging of the wrist and forearm. Genetic testing can also be conducted to identify mutations in the SHOX gene.

Celine from the Gorbenko Advocacy Center provides free information and support to individuals and families affected by Léri-Weill dyschondrosteosis. Their website offers additional resources for learning more about the condition and connecting with other patients.

Overall, Léri-Weill dyschondrosteosis is a relatively rare genetic condition associated with mutations in the SHOX gene. It is most often found in females and can be diagnosed through clinical evaluation, radiographic imaging, and genetic testing.

Causes

Léri-Weill dyschondrosteosis is a rare genetic condition characterized by short stature, skeletal abnormalities, and wrist deformities. It is also known as LWD or Léri-Weill syndrome. Although the exact cause of Léri-Weill dyschondrosteosis is not fully understood, it is thought to be primarily caused by mutations or deletions in specific genes on the sex chromosomes.

One of the genes associated with Léri-Weill dyschondrosteosis is the SHOX gene, which is located on the X and Y chromosomes. Mutations or deletions in the SHOX gene can disrupt the normal development of bone and cartilage, leading to the characteristic symptoms and signs of Léri-Weill dyschondrosteosis.

Léri-Weill dyschondrosteosis follows an autosomal dominant inheritance pattern, which means that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition. However, most cases of Léri-Weill dyschondrosteosis occur sporadically, meaning they are not inherited from a parent and occur by chance.

The Léri-Weill dyschondrosteosis condition is also often associated with a related condition called idiopathic short stature (ISS), which is characterized by short stature without any skeletal abnormalities or other symptoms. The SHOX gene mutations or deletions associated with Léri-Weill dyschondrosteosis can also cause ISS in some individuals.

Testing for mutations or deletions in the SHOX gene can help confirm a diagnosis of Léri-Weill dyschondrosteosis. Genetic testing can be done using various techniques, such as DNA sequencing or targeted gene panel testing. These tests are typically performed on a blood or saliva sample from the patient.

Additional genes, such as the homeobox genes in the DLX and HOX families, have also been implicated in the development of Léri-Weill dyschondrosteosis, although their exact role in the condition is still under investigation.

For more information on Léri-Weill dyschondrosteosis and related genetic disorders, resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed can provide scientific articles, references, and support for patients and healthcare professionals.

Learn more about the gene associated with Léri-Weill dyschondrosteosis

In 1997, it was discovered that Léri-Weill dyschondrosteosis is caused by genetic mutations in the SHOX gene. This gene is located on the short arms of both the X and Y chromosomes.

When the SHOX gene is not functioning properly, it leads to the characteristic signs and symptoms of Léri-Weill dyschondrosteosis, including short stature, bowed legs, and a characteristic “Madelung deformity” of the wrists.

This condition is considered a rare genetic disorder, and it follows an autosomal dominant pattern of inheritance. This means that a mutation in just one copy of the SHOX gene is enough to cause the condition. However, the severity of the symptoms can vary from person to person.

Additional research has identified other genes that can contribute to Léri-Weill dyschondrosteosis, such as the GHR, NPR2, and IGF1R genes. These genes play a role in growth and bone development.

Genetic testing can be done to confirm a diagnosis of Léri-Weill dyschondrosteosis. This testing can detect mutations in the SHOX gene, as well as other associated genes. It can also provide important information for patients and their families about the inheritance pattern and recurrence risk.

If you are interested in learning more about the gene associated with Léri-Weill dyschondrosteosis, there are many resources available. Scientific articles and free articles can be found on pubmed.gov, and the Online Mendelian Inheritance in Man (OMIM) database provides comprehensive information on this condition and the associated genes.

Inheritance

Léri-Weill dyschondrosteosis is inherited in an autosomal dominant manner. This means that one copy of the altered gene in each cell is sufficient to cause the condition.

The characteristic signs and symptoms of Léri-Weill dyschondrosteosis can vary greatly among affected individuals, even within the same family. Some cases of the condition occur in people with no history of the disorder in their family. These cases are classified as idiopathic, meaning the cause is unknown.

The frequency of Léri-Weill dyschondrosteosis is unknown, but it is considered to be a rare condition.

Léri-Weill dyschondrosteosis is caused by mutations in the SHOX gene. This gene provides instructions for making a protein that is involved in the growth and development of bones and other tissues. Mutations in the SHOX gene disrupt the normal function of this protein, leading to the signs and symptoms of the condition.

Other Names for This Condition

Léri-Weill dyschondrosteosis
LWD
Léri-Weill syndrome
Madelung-like deformity
Genetic short stature
Disproportionate short stature with Madelung deformity of the wrist

Léri-Weill dyschondrosteosis, also known as LWD or Léri-Weill syndrome, is a rare genetic condition that affects the growth of bones in the wrist and arms. It is characterized by short stature, particularly in males, and abnormalities in the length of the bones in the forearm.

The exact causes of Léri-Weill dyschondrosteosis are not fully understood, but it is believed to be associated with a mutation in a gene called SHOX. SHOX gene is involved in regulating bone growth, and mutations in this gene can cause abnormalities in the growth of bones in the wrist and arms.

Léri-Weill dyschondrosteosis is inherited in an autosomal dominant manner, which means that each child of an affected individual has a 50% chance of inheriting the condition. However, not all cases of Léri-Weill dyschondrosteosis are inherited and can occur as a result of new mutations in the SHOX gene.

The frequency of Léri-Weill dyschondrosteosis is unknown, but it is considered a rare condition. It has been reported in individuals from various ethnic backgrounds.

The signs and symptoms of Léri-Weill dyschondrosteosis can vary widely among affected individuals. Some common features include short stature, shortening of the forearms, and Madelung deformity of the wrist, which is characterized by abnormal growth and alignment of the bones in the wrist.

Diagnosis of Léri-Weill dyschondrosteosis can be confirmed through genetic testing to detect mutations in the SHOX gene. In some cases, X-rays of the wrist and arms may be done to evaluate the skeletal abnormalities.

There is no cure for Léri-Weill dyschondrosteosis, but treatment may involve managing the symptoms and providing support for affected individuals. This can include growth hormone therapy to help improve height, orthopedic interventions to correct bone deformities, and physical therapy to improve strength and mobility.
