ELN gene – Austra Health

The ELN gene, also known as elastin, is a key component in the development and maintenance of various tissues and organs in the body. Mutations in the ELN gene have been found to be associated with a range of genetic conditions, including supravalvular aortic stenosis (SVAS) and Williams-Beuren syndrome (WBS).

In each of these conditions, genetic changes in the ELN gene lead to abnormalities in the structure and function of the cardiovascular system. SVAS is characterized by the narrowing of the aortic valve, while WBS is a multi-system disorder that affects various organs and tissues.

Scientists have identified a number of genetic variants and duplications in the ELN gene that are associated with these conditions. Research articles on PubMed and other scientific resources provide valuable information on the clinical features, diagnosis, and testing options for individuals with ELN gene mutations.

The ELN gene is responsible for the production of elastin, a protein that gives flexibility and elasticity to tissues such as the skin, blood vessels, and lungs. When the ELN gene is defective or mutated, the production of elastin is reduced, leading to the enlargement and stretching of blood vessels and other tissues.

The ELN gene is listed on the Online Mendelian Inheritance in Man (OMIM) database as the cause of Williams syndrome, a complex genetic condition characterized by cardiovascular problems, distinctive facial features, and intellectual disabilities. Research and genetic testing continue to provide insights into the role of the ELN gene in various diseases and conditions.

Health Conditions Related to Genetic Changes

Genes play a crucial role in determining the health conditions of an individual. Genetic changes can lead to various diseases and abnormalities in the body. One such gene that is associated with certain health conditions is the ELN gene, which encodes for elastin.

Elastin is a protein found in the connective tissues of the body. It provides elasticity and strength to the blood vessels, lungs, skin, and other organs. Mutations or abnormalities in the ELN gene can result in health problems related to the vascular system.

One of the health conditions related to genetic changes in the ELN gene is Supravalvular Aortic Stenosis (SVAS). SVAS is a cardiovascular defect characterized by the narrowing of the aortic valve, which obstructs the blood flow from the heart. This condition can lead to heart problems, abnormal blood pressure, and other cardiovascular complications.

Genetic tests can be done to identify the presence of genetic changes in the ELN gene. Duplication or deletion of this gene can be detected through certain tests, such as fluorescence in situ hybridization (FISH) or chromosomal microarray analysis (CMA). These tests can provide valuable information about the genetic component of health conditions.

Another health condition associated with genetic changes in the ELN gene is Williams-Beuren syndrome. This syndrome is characterized by a deletion of a small piece of chromosome 7, which includes the ELN gene. Individuals with Williams-Beuren syndrome often have cardiovascular problems, developmental delay, and distinct facial features.

Cutis Laxa is yet another health condition that can result from genetic changes in the ELN gene. Cutis Laxa is a rare disorder characterized by loose and sagging skin due to a deficiency of elastin in the connective tissues. This condition can affect various parts of the body, including the face, neck, and limbs.

To learn more about health conditions related to genetic changes in the ELN gene, various scientific articles, databases, and genetic resources can be consulted. PubMed and OMIM are two widely used resources that provide detailed information on genes, diseases, and genetic variants. These resources contain references to articles and studies that discuss the relationship between genetic changes and health conditions.

In conclusion, genetic changes in the ELN gene can lead to several health conditions, including SVAS, Williams-Beuren syndrome, and Cutis Laxa. Proper testing and analysis of genetic information can help diagnose these conditions and provide appropriate medical interventions.

Cutis laxa

Cutis laxa is a genetic disorder characterized by loose and sagging skin. It is caused by mutations in genes involved in the production and maintenance of elastin, a component of the body’s connective tissues. Elastin provides elasticity and strength to various tissues and organs, including the skin, blood vessels, and heart.

There are several types and subtypes of cutis laxa, each associated with different genes and genetic defects. One of the well-known forms of cutis laxa is the autosomal dominant cutis laxa type 1 (ADCL1), which is caused by mutations in the ELN gene located on chromosome 7q11.23. Mutations in this gene lead to decreased elastin production and stretched-out elastin fibers, resulting in the characteristic loose and wrinkled skin.

Patients with ADCL1 may also have associated cardiovascular problems, such as supravalvular aortic stenosis (SVAS), aortic enlargement, and other heart defects. Testing for the ELN gene mutations can be done to confirm the diagnosis of ADCL1. This can be done through genetic testing, where a blood or tissue sample is obtained from the patient and processed to analyze the DNA. The presence of a mutated copy of the ELN gene confirms the diagnosis of ADCL1.

Genetic testing for cutis laxa can also be useful in identifying other genetic diseases with similar symptoms. For example, mutations in the ELN gene are also associated with Williams-Beuren syndrome, a disorder characterized by developmental delay, intellectual disability, and unique facial features.

Scientific articles and databases, such as PubMed, provide additional information on the genetic basis of cutis laxa and related diseases. These resources catalog the identified genes, variants, and associated clinical features for different types of cutis laxa. The information derived from these studies helps researchers and healthcare professionals in understanding the underlying genetic changes, developing appropriate diagnostic tests, and improving patient care.

In conclusion, cutis laxa is a genetic disorder characterized by loose and sagging skin due to mutations in genes involved in elastin production. Genetic testing plays a crucial role in confirming the diagnosis and identifying other associated genetic diseases. Understanding the genetic basis of cutis laxa and related conditions can lead to better diagnostic techniques and improved healthcare outcomes for affected individuals.

Supravalvular aortic stenosis

Supravalvular aortic stenosis (SVAS) is a cardiovascular condition that is listed as a rare disease in the Genetic and Rare Diseases Information Center (GARD) and Orphanet. It is characterized by abnormal narrowing or constriction of the aorta, the main artery that carries oxygen-rich blood from the heart to the rest of the body.

SVAS can be caused by genetic changes in the elastin gene (ELN). Mutations in this gene result in the development of elastin abnormalities, leading to the formation of narrowed or stretched sections of the aorta. SVAS is associated with Williams-Beuren syndrome, which is a genetic disorder that causes various developmental and health problems.

SVAS is inherited in an autosomal dominant manner. This means that a person with SVAS has a 50% chance of passing the condition on to each of their children. Genetic testing can be performed to identify mutations in the ELN gene and confirm a diagnosis of SVAS.

SVAS is a component of a larger category of elastin-related disorders, including autosomal dominant cutis laxa type 1 (ADCL1) and other vascular diseases. The condition can lead to complications such as heart enlargement and reduced blood flow to vital organs. SVAS can also be associated with intellectual or developmental disabilities in some cases.

To diagnose SVAS, medical professionals may perform tests such as echocardiography, which uses sound waves to create images of the heart, or angiography, which involves injecting a contrast dye into the blood vessels and taking X-ray images. These tests help visualize the abnormal narrowing or stretching of the aorta.

Additional resources and information about SVAS can be found on websites such as PubMed, OMIM, and the GARD. These databases provide scientific articles, references, and catalog information related to SVAS and other genetic conditions. The ELN gene defect from SVAS has been identified on chromosome 7q11.23, and research is ongoing to better understand the underlying genetic causes and develop potential treatments for SVAS and related diseases.

7q1123 duplication syndrome

7q1123 duplication syndrome is a genetic disorder caused by a duplication of a specific region of chromosome 7, known as the 7q1123 region. This duplication leads to an abnormal increase in the number of copies of genes within this region, including the ELN gene.

The ELN gene, located on chromosome 7q1123, is responsible for producing a protein called elastin. Elastin is a major component of elastic fibers, which provide strength and flexibility to various tissues in the body, including blood vessels, skin, and organs.

Individuals with 7q1123 duplication syndrome have an extra copy of the ELN gene, resulting in increased production of elastin. This excess elastin can cause problems in the cardiovascular system, particularly in the aorta and its branches.

Some of the key clinical features associated with 7q1123 duplication syndrome include supravalvular aortic stenosis (SVAS), which is a narrowing of the aortic valve; aortic enlargement; cardiovascular abnormalities; and cutis laxa, which is a condition characterized by loose and sagging skin.

To diagnose 7q1123 duplication syndrome, genetic testing is typically performed to identify the duplication of the 7q1123 region and the increase in the number of copies of the ELN gene. Additional tests, such as imaging studies and cardiovascular evaluations, may be done to assess the severity and impact of the syndrome on the affected individual’s health.

Further scientific articles and references for 7q1123 duplication syndrome can be found in databases such as PubMed and OMIM. These sources provide valuable information on the syndrome, including clinical manifestations, genetic changes, and available treatment options.

In summary, 7q1123 duplication syndrome is a rare genetic condition caused by a duplication of the 7q1123 region, resulting in an increased number of copies of the ELN gene. This excess elastin production can lead to cardiovascular problems, such as SVAS and aortic enlargement, as well as other health issues like cutis laxa. Genetic testing and additional medical evaluations are crucial for accurate diagnosis and management of this syndrome.

Williams syndrome

Williams syndrome is a genetic abnormality that is caused by a defect in the elastin gene (ELN) on chromosome 7q11.23. It is also known as Williams-Beuren syndrome. This condition is characterized by cardiovascular problems, intellectual disabilities, distinctive facial features, and a unique personality profile.

One of the main components of Williams syndrome is the stretchy or laxaity of the blood vessels and tissues due to reduced elastin production. This can result in various cardiovascular conditions such as supravalvular aortic stenosis (SVAS), aortic enlargement, and other vascular abnormalities. These changes in the blood vessels can lead to heart defects, including aortic stenosis, and other heart-related conditions.

There are several diagnostic tests available for Williams syndrome, including genetic tests to identify the deletion or duplication of the ELN gene, as well as clinical evaluations and medical imaging to assess the cardiovascular and other associated problems. The Online Mendelian Inheritance in Man (OMIM) database provides additional information on the genetics and clinical features of Williams syndrome.

According to scientific articles listed on PubMed, some patients with Williams syndrome may exhibit connective tissue abnormalities, such as lax skin (cutis laxa), joint laxity, and other skeletal abnormalities. These individuals may also have developmental delays, learning disabilities, and behavioral or psychological issues.

The Registry and Database for Williams-Beuren Syndrome (WBS) is a valuable resource for gathering and processing health-related information on individuals with Williams syndrome. They provide access to research articles, clinical resources, and other relevant information on this condition.

In conclusion, Williams syndrome is a genetic disorder characterized by cardiovascular abnormalities, developmental delays, and distinct facial features. The deletion or duplication of the ELN gene on chromosome 7q11.23 is the main genetic cause of this condition.
