Lamellar ichthyosis is a rare genetic skin disorder that affects the cornified layer of the skin. This condition can cause significant distress and loss of quality of life to those affected. Lamellar ichthyosis is one of the many forms of congenital ichthyoses, a group of inherited disorders characterized by dry, thickened, and scaly skin.
Researchers have identified several genes that are associated with lamellar ichthyosis, including TGM1, ALOXE3, ALOX12B, and ABCA12. These genes play a crucial role in the production and maintenance of the skin’s protective barrier. Mutations in these genes can disrupt this process, leading to the symptoms observed in lamellar ichthyosis patients.
Despite the rarity of this condition, scientific research and advocacy efforts have brought about significant progress in understanding its causes, inheritance patterns, and potential treatment options. The National Institutes of Health’s Genetic and Rare Diseases Information Center provides comprehensive resources and additional information about lamellar ichthyosis and other related diseases.
ClinicalTrials.gov and PubMed are valuable resources for finding studies and articles related to lamellar ichthyosis. These platforms allow patients and researchers to learn about the latest advancements in the field and connect with others who are affected by the condition. Additionally, several patient registries and advocacy groups, such as the Ichthyosis Registry and Research Network, provide support and resources for individuals and families affected by lamellar ichthyosis.
Frequency
Lamellar ichthyosis is a rare genetic condition. It is estimated to affect approximately 1 in 300,000 to 500,000 people worldwide.
Scientific studies have identified several genes associated with lamellar ichthyosis. The most common gene involved is TGM1, which is responsible for the production of an enzyme called transglutaminase 1. Mutations in the TGM1 gene result in a loss of function of this enzyme, leading to the abnormal formation of the skin’s protective barrier.
Administrative spending is particularly problematic in United States hospitals, where it makes up about 25% of total hospital spending and accounts for hundreds of billions of dollars in healthcare spending annually, The Commonwealth Fund The percentage of total hospital spending devoted to administration is highest in for-profit hospitals, followed by nonprofit hospitals, teaching hospitals, and finally public hospitals. Outdated reimbursement and reporting methods are a big part of the administrative cost, says Salvo-Wendt. “Reimbursing in bundled payments instead of itemizing each service or component would produce instant savings of administrative costs.”
The frequency of lamellar ichthyosis varies in different populations. For example, it is more commonly reported in populations of Pakistani and Japanese descent.
Additional genes, such as ALOXE3, ALOX12B, and ADRB3, have also been identified as causes of the condition.
There are several resources available for individuals and families affected by lamellar ichthyosis. The National Registry for Ichthyosis and Related Disorders is a comprehensive catalog of information on the condition, including information on clinical trials, research studies, and genetic testing.

Causes
Lamellar ichthyosis (LI) is a rare genetic condition characterized by the abnormal development of the skin. It is caused by mutations in certain genes that are involved in the production of a protein called transglutaminase 1 (TGM1) or other genes associated with the cornified envelope, a structure that helps form the protective barrier of the skin.
LI is generally inherited in an autosomal recessive manner, which means that both copies of the gene responsible for the condition must be mutated in order for a person to have LI. There are several identified genes associated with LI, including TGM1 and other genes such as ALOXE3, ALOX12B, ABCA12, and NIPAL4. Mutations in these genes have been shown to cause LI in affected individuals.
According to scientific studies and clinicaltrialsgov, mutations in the TGM1 gene are the most common cause of LI, accounting for approximately 41-50% of cases. Mutations in the ALOXE3, ALOX12B, ABCA12, and NIPAL4 genes are less common causes of the condition.
The loss-of-function mutations in TGM1 and other associated genes lead to a defective cornified envelope, resulting in the characteristic features of LI, such as thick, scaly skin and a collodion membrane at birth.
Interestingly, there have been reported cases of LI with no identified mutations in the known genes associated with the condition. These cases may be due to variations in other genes or genetic factors that have not yet been identified.
Research is ongoing to further understand the genetic basis of LI and identify additional genes involved in its development. DNA testing is available to confirm a diagnosis of LI and can help identify the specific genetic mutations causing the condition.
Patient registries, advocacy groups, and scientific resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed provide additional information and support for individuals and families affected by LI. These resources can help patients and their families learn more about the condition, find articles and scientific studies related to LI, and connect with other individuals and families affected by the condition.
Learn more about the genes associated with Lamellar ichthyosis
Lamellar ichthyosis (LI) is a rare congenital condition that causes the loss of the cornified layer of the skin, resulting in thick, scaly, and dry skin. It is associated with several genes that play a role in the development of the skin barrier.
One of the genes associated with LI is TGM1 (transglutaminase 1). Mutations in the TGM1 gene are the most common cause of LI. The TGM1 gene encodes an enzyme that is essential for the formation of the cornified layer of the skin. Mutations in this gene lead to an impaired skin barrier function, causing the symptoms of LI.
Another gene associated with LI is ALOX12B. Mutations in the ALOX12B gene result in a deficiency of the enzyme 12R-lipoxygenase, which is involved in the synthesis of lipids in the skin. This deficiency leads to abnormal skin development and the characteristic symptoms of LI.
Other less common genes associated with LI include NIPAL4, CYP4F22, and ABCA12. Mutations in these genes also affect skin barrier function and result in the development of LI.
Researchers have identified additional genes associated with LI through genetic testing and studies on patient populations. These genes provide further insight into the causes and mechanisms of LI.
If you or someone you know has been diagnosed with LI, there are resources and support available. The National Registry for Ichthyosis and Related Disorders is a valuable resource for information, support, and connections to research studies and clinical trials. Additionally, advocacy organizations like the Foundation for Ichthyosis and Related Skin Types (FIRST) and the Ichthyosis Advocacy Group provide support and resources for individuals and families affected by LI.
For more information about the genes associated with LI, you can refer to scientific articles and databases such as OMIM (Online Mendelian Inheritance in Man), PubMed, and the Human Gene Mutation Database (HGMD).

Inheritance
Lamellar ichthyosis (LI) is a rare genetic skin disorder that is inherited in an autosomal recessive manner. This means that both parents must carry a mutation in the same gene for their child to have the condition.
The most common gene associated with LI is the TGM1 gene, which provides instructions for making an enzyme called transglutaminase 1. Mutations in this gene result in a loss of function of transglutaminase 1, leading to the characteristic symptoms of LI.
Other genes have also been identified as causing LI, including the ALOXE3, ALOX12B, NIPAL4, and CYP4F22 genes. Mutations in these genes can lead to a similar loss of function and result in the development of LI.
Genetic testing may be used to confirm a diagnosis of LI and to identify the specific gene mutation responsible for the condition. This testing can be done at specialized genetic centers or through commercial genetic testing companies.
It is important for patients and their families to learn about the genetics of LI and to stay informed about ongoing research and clinical trials. Resources such as the Online Mendelian Inheritance in Man (OMIM) database, clinicaltrials.gov, and scientific articles can provide additional information about the condition and related research studies.
In addition to genetic testing and research, support and advocacy resources are available for individuals and families affected by LI. Rare disease registries and advocacy organizations, such as the Foundation for Ichthyosis and Related Skin Types (FIRST), can provide information, support, and connections to other individuals and families dealing with LI.
Overall, the inheritance of LI is a complex and rare genetic condition. Understanding the genes and inheritance patterns associated with LI can help with diagnosis, treatment, and support for individuals and families affected by this condition.
