TGM5 gene – Austra Health

The TGM5 gene is a genetic variant that has been associated with a rare syndrome called Transglutaminase 5 deficiency. This syndrome is characterized by changes in the skin, particularly the cornified envelope, which is the outermost layer of the skin. Individuals with this syndrome may experience peeling of the skin, particularly on the palms of the hands and the soles of the feet.

The TGM5 gene variant was first identified in a European cohort of individuals with this syndrome. The discovery of this gene has provided important insights into the molecular basis of this rare condition, and has led to the development of diagnostic tests for its identification.

In addition to its role in this specific syndrome, the TGM5 gene has also been implicated in other genetic conditions related to the skin, including Acral peeling skin syndrome and Oddi-Terrinoni-Steensel syndrome. These conditions are characterized by similar changes in the skin, and are thought to be caused by mutations in the TGM5 gene.

More information on the TGM5 gene, including references to scientific articles and resources for genetic testing, can be found in related databases such as OMIM and PubMed. These resources provide additional information on the protein and amino acid changes associated with this gene variant, as well as its role in other envelope diseases.

In conclusion, the TGM5 gene is a key player in the development of various genetic syndromes and diseases affecting the skin. Further research is needed to fully understand its role in these conditions and develop effective treatments for affected individuals.

Health Conditions Related to Genetic Changes

Genetic changes in the TGM5 gene can lead to various health conditions that affect the skin. The TGM5 gene codes for a protein involved in the formation of the cornified envelope, which is a protective layer in the skin.

One of the health conditions related to genetic changes in the TGM5 gene is Acral Peeling Skin Syndrome (APSS). APSS is a rare skin disorder characterized by peeling of the skin on the hands and feet. It is caused by mutations in the TGM5 gene, which result in a dysfunctional protein.

Another health condition associated with genetic changes in the TGM5 gene is Odontomicronychial Dysplasia (OD). OD is a rare syndrome characterized by abnormal nail and dental development. Mutations in the TGM5 gene have been identified as a cause of this syndrome.

Scientific articles and other resources related to these health conditions and genetic changes in the TGM5 gene can be found in various databases and registries. Some of the databases and resources include PubMed, European Variant Archive, OMIM (Online Mendelian Inheritance in Man), and the Genetic Testing Registry.

For additional information and testing resources, references to articles and studies can be found in these databases. They provide information on the specific genetic changes in the TGM5 gene, the amino acid changes in the protein, and other related genes and conditions.

Testing for genetic changes in the TGM5 gene can be helpful in diagnosing these health conditions. Genetic testing can help identify the specific genetic changes present in an individual and provide information on their potential impact on health.

In conclusion, genetic changes in the TGM5 gene can lead to various health conditions affecting the skin, such as Acral Peeling Skin Syndrome and Odontomicronychial Dysplasia. The scientific literature and various databases provide valuable information and resources for studying these conditions and understanding the underlying genetic changes.

Acral peeling skin syndrome

Acral peeling skin syndrome is a rare genetic disorder that affects the skin. It is caused by mutations in the TGM5 gene, which provides instructions for making a protein called transglutaminase 5. This protein is involved in the formation of the cornified envelope, a structure that helps protect the skin from damage and dehydration.

Acral peeling skin syndrome is characterized by peeling of the skin, especially on the hands and feet. The peeling usually starts in infancy or early childhood and may be triggered or worsened by friction, heat, or moisture. The affected skin may also be red, inflamed, and prone to blistering. In some cases, the condition can also affect the nails, leading to nail abnormalities.

Currently, there is no specific treatment for acral peeling skin syndrome. However, symptomatic management can include avoiding triggers that worsen the skin peeling, keeping the skin moisturized, and using emollients and mild topical corticosteroids to reduce inflammation. Regular follow-up with a dermatologist is recommended to monitor the condition and provide appropriate care.

Research on acral peeling skin syndrome is ongoing, and scientists continue to investigate the underlying causes and potential treatment options for this condition. Various scientific articles on the syndrome can be found in databases such as PubMed or OMIM. Genetic testing can help confirm the diagnosis and identify the specific genetic variant responsible for the condition.

Additional information and resources for patients and healthcare providers can be found on the websites of organizations and registries dedicated to genetic conditions, such as the European Network of Genetic and Congenital Anomalies (EuNeGCA) or the Online Mendelian Inheritance in Man (OMIM) database. These resources provide access to genetic testing laboratories, clinical trials, research studies, and support groups for patients and families affected by acral peeling skin syndrome.
