The TGM1 gene is a recessive genetic cause of lamellar ichthyosis, a group of skin disorders. This gene, also known as transglutaminase-1, is responsible for encoding an enzyme that plays a crucial role in the formation of the epidermal barrier. Mutations in the TGM1 gene can lead to the production of a faulty enzyme, resulting in a variety of skin conditions.

Scientists have conducted extensive research on the TGM1 gene and its associated disorders. Many articles examining this gene and its variants have been published in scientific journals and can be found on databases such as PubMed and OMIM. These resources provide valuable information for healthcare professionals and researchers studying the genetic causes of skin diseases.

Patients with TGM1 gene disorders often present with symptoms such as collodion membrane at birth, and later develop scaling and dry skin. The severity of the condition can vary depending on the specific variant of the gene. Additional epidermal conditions may also be related to TGM1 gene mutations.

A key resource for information on the TGM1 gene and related disorders is the TGM1 gene catalog, which provides a comprehensive list of genetic variations and associated diseases. This catalog serves as a valuable reference for genetic testing laboratories and researchers studying the TGM1 gene.

The discovery of the TGM1 gene and its role in the development of skin disorders has led to significant advances in the diagnosis and treatment of these conditions. Genetic testing for TGM1 gene mutations can now be used to confirm a diagnosis and guide treatment plans for affected individuals.

Genetic changes in the TGM1 gene can cause various health conditions, particularly those affecting the skin. The TGM1 gene provides instructions for making an enzyme called transglutaminase-1, which is responsible for the normal functioning of the skin.

Fears over not being able to afford health insurance or medical care are among the top reasons why Americans are delaying retirement. From 2000 to 2016, the number of Americans 65 and older working full-time or part-time rose by six% to include almost 9 million people, according to the Pew Research Center.

One of the health conditions associated with genetic changes in the TGM1 gene is lamellar ichthyosis. Lamellar ichthyosis is a rare genetic disorder characterized by the presence of thick, plate-like scales on the skin. Infants with this condition are typically born with a shiny, tight, and thickened outer layer of skin known as a collodion membrane. Lamellar ichthyosis is inherited in an autosomal recessive manner, meaning that both copies of the TGM1 gene must have genetic changes for the condition to occur.

Another health condition related to genetic changes in the TGM1 gene is epidermal ichthyosis. Epidermal ichthyosis is a group of genetic disorders that affect the skin’s ability to shed dead cells properly, leading to the formation of scales. There are several types of epidermal ichthyosis, and some of them are caused by changes in the TGM1 gene.

Patients with these and other related health conditions may undergo genetic testing to identify genetic changes in the TGM1 gene. Genetic testing can help confirm a diagnosis and provide valuable information for patient management and counseling.

Scientific resources, such as PubMed and OMIM, provide additional information on the genetic changes associated with these conditions. The Human Gene Mutation Database and other genetic databases are also valuable resources for gathering information on gene variants and their associated health conditions.

The International Ichthyosis Consortium (IIC) maintains a registry of patients with various types of ichthyosis, including those caused by genetic changes in the TGM1 gene. The IIC registry serves as a centralized repository of clinical and genetic information, facilitating research and collaboration in the field of ichthyosis.

Healthcare professionals and researchers can find articles, references, and other resources related to TGM1 gene changes and associated diseases in scientific journals and online databases. These resources can aid in understanding the molecular basis of these conditions and make information accessible for healthcare professionals and patients.

Lamellar ichthyosis

Lamellar ichthyosis is a genetic disorder caused by mutations in the TGM1 gene. It is a scientific name for a group of conditions that affect the skin. Lamellar ichthyosis is also known as collodion baby, ichthyosis, or torch oil baby. The condition is characterized by the presence of a tight, shiny layer of skin called a collodion membrane at birth, which later sheds and the skin becomes thick, scaly, and rough.

See also  Lateral meningocele syndrome

Genetic testing is often recommended for patients with symptoms of lamellar ichthyosis to confirm the diagnosis and identify specific gene mutations. Additional testing may also be performed to determine the severity of the condition and assess any related health changes.

The TGM1 gene is associated with an autosomal recessive form of lamellar ichthyosis. Mutations in this gene can make patients more prone to developing the condition. This gene is listed in the OMIM database, a catalog of human genes and genetic disorders, as a causative gene for lamellar ichthyosis.

Infants with lamellar ichthyosis often require intensive care and specialized treatment to manage their skin symptoms. The transglutaminase-1 protein, encoded by the TGM1 gene, is responsible for maintaining the integrity of the skin barrier. Mutations in the TGM1 gene result in the malfunction of this protein, leading to the characteristic skin abnormalities seen in lamellar ichthyosis.

The Sprecher research group has published several articles on the genetic basis and novel mutations in lamellar ichthyosis. Their research has contributed to our understanding of the disease and the role of the TGM1 gene. Additionally, other genes have been associated with lamellar ichthyosis, and information on these genes can be found in scientific articles and databases such as PubMed.

For patients and family members seeking more information on lamellar ichthyosis, there are various resources available, including patient registries, support groups, and genetic testing services. These resources can provide valuable information on the disease, available treatments, and support for individuals and families affected by lamellar ichthyosis.

Other disorders

Recessive mutations in the transglutaminase-1 (TGM1) gene can cause a range of conditions in patients. Apart from the well-known health condition ichthyosis, there are several other related disorders that have been identified.

One variant of the TGM1 gene is responsible for causing lamellar ichthyosis, a form of ichthyosis that affects infants from birth. Lamellar ichthyosis is characterized by a collodion baby appearance, where the newborn’s skin is covered in a shiny, tight, and transparent membrane.

In addition to lamellar ichthyosis, other disorders caused by mutations in the TGM1 gene include epidermal lamellar ichthyosis, lamellar ichthyosis type 2, nonbullous congenital ichthyosiform erythroderma, and collodion baby. These disorders result in abnormalities in the production of the protein transglutaminase-1 and lead to various skin and health-related symptoms.

Testing for these disorders can be done through genetic testing, and there are resources available to assist healthcare professionals and patients. The TORO (Testing Otherwise Rarely Offered) registry provides information on genetic testing for rare and novel genes, including the TGM1 gene. The registry catalog includes references to scientific articles and databases such as OMIM (Online Mendelian Inheritance in Man) that list the names of genes and the associated disorders they cause.
