Chanarin-Dorfman syndrome, also known as Triglyceride Storage Disease with Ichthyosis, is a rare genetic condition. It is named after two scientists, M.B. Chanarin and N. Dorfman, who first described the syndrome in 1974. This syndrome is associated with mutations in the ABHD5 gene.

People with Chanarin-Dorfman syndrome have an abnormal build-up of fats called triglycerides in various organs of the body, including the liver. This can cause liver dysfunction and other serious health problems. One of the main features of the syndrome is the presence of dry, scaly skin, known as ichthyosis.

Scientific research and genetic testing studies have provided valuable information about the causes, inheritance patterns, and clinical features of Chanarin-Dorfman syndrome. The frequency of this condition is unknown, but it is believed to be a rare disease.

For individuals affected by Chanarin-Dorfman syndrome and their families, there are several support and advocacy groups that provide resources and information. Websites like OMIM, PubMed, and ClinicalTrials.gov have articles and additional references stored with scientific information about this syndrome. Genetic testing and clinical trials are also available to learn more about the condition and potential treatments.

Overall, Chanarin-Dorfman syndrome is a rare genetic disorder associated with the ABHD5 gene. It is characterized by triglyceride storage in various organs, liver dysfunction, and dry, scaly skin. Research and genetic testing studies continue to uncover more information about this condition, which can lead to improved diagnosis and treatment options for affected individuals.

Frequency

The Chanarin-Dorfman syndrome is a rare genetic condition that causes the storage of fats in various organs of the body, including the liver. It is also known as neutral lipid storage disease with ichthyosis (NLSDI). The frequency of this syndrome is estimated to be 1 in 100,000 to 1 in 300,000 individuals worldwide.

The older you get, the more you will be forced to spend on healthcare. A couple retiring at age 65 in 2018 will spend $280,000, on average, on medical costs throughout their retirement, not counting the expense of over-the-counter medications or the cost of living in a nursing home, CBS News

The syndrome is caused by mutations in the ABHD5 gene, which is involved in the breakdown of fats in cells. Mutations in this gene result in the improper processing and storage of fats, leading to the characteristic symptoms of the syndrome.

There are not many research articles or clinical trials specifically focused on the Chanarin-Dorfman syndrome. However, more information about the genetic inheritance, clinical features, and other aspects of the syndrome can be found in the OMIM catalog and PubMed, which are comprehensive databases of genetic and medical information. These resources may also provide information on patient support and advocacy groups associated with the syndrome.

Further genetic testing and research studies are needed to learn more about the underlying causes and effects of the Chanarin-Dorfman syndrome. ClinicalTrials.gov is a valuable resource for finding ongoing clinical trials and studies related to rare diseases like this syndrome.

Additional information and support for individuals with the Chanarin-Dorfman syndrome can be obtained from the National Center for Advancing Translational Sciences (NCATS), which provides resources for genetic testing and patient support. Genetic counseling may also be beneficial for individuals and families affected by this condition.

References and citation of scientific articles related to the Chanarin-Dorfman syndrome can be found in PubMed or other scientific databases. These articles can provide further insights into the genetic basis, clinical manifestations, and management of the syndrome.

Causes

Chanarin-Dorfman syndrome (CDS) is a rare genetic disorder. It is caused by mutations in the ABHD5 gene, also known as CGI-58. The ABHD5 gene provides instructions for making an enzyme called α/β-hydrolase domain-containing protein 5. This enzyme is involved in the breakdown of triglycerides, which are a type of fat that is stored in cells for energy.

When there is a mutation in the ABHD5 gene, the α/β-hydrolase domain-containing protein 5 enzyme is not produced or does not function correctly. This leads to the accumulation of triglycerides in various tissues and organs, including the liver, skin, muscles, and eyes.

The inheritance pattern of Chanarin-Dorfman syndrome is autosomal recessive. This means that an individual must inherit two copies of the mutated gene, one from each parent, to develop the condition. If both parents carry one copy of the mutated gene, each of their children has a 25% chance of inheriting the disorder.

There are different mutations in the ABHD5 gene that can cause Chanarin-Dorfman syndrome, and the severity of the condition can vary among affected individuals. Some individuals with the disorder may have a milder form of the disease, while others may have more severe symptoms.

Further research is ongoing to understand the exact mechanisms by which these mutations lead to the storage of triglycerides and the development of the characteristic features of Chanarin-Dorfman syndrome.

Chanarin-Dorfman syndrome is a rare genetic condition that causes lipid storage disorders. The gene associated with this syndrome is called ABHD5 (alpha/beta hydrolase domain-containing protein 5). This gene provides instructions for making an enzyme that is involved in lipid metabolism.

Research has shown that mutations in the ABHD5 gene can disrupt the normal function of the enzyme, leading to the accumulation of lipids in various cells and tissues throughout the body. This accumulation can result in the signs and symptoms of Chanarin-Dorfman syndrome.

For additional information about the ABHD5 gene and its association with Chanarin-Dorfman syndrome, please refer to the following resources:

• The OMIM database (Online Mendelian Inheritance in Man) – a catalog of human genes and genetic disorders, including Chanarin-Dorfman syndrome and the associated ABHD5 gene. The OMIM entry for Chanarin-Dorfman syndrome provides detailed information on the genetic basis of the condition, as well as references to scientific articles for further reading.

In summary, the ABHD5 gene is associated with Chanarin-Dorfman syndrome, a rare genetic condition characterized by lipid storage disorders. Understanding the genetic basis of the syndrome is important for genetic testing, research, and developing potential treatments for affected individuals.

Inheritance

The Chanarin-Dorfman syndrome is a rare genetic disorder characterized by the accumulation of lipid droplets in various tissues of the body, including the liver. It is associated with mutations in the ABHD5 gene. Inheritance of the syndrome follows an autosomal recessive pattern, which means that both copies of the gene must be mutated for an individual to develop the condition.

Testing for mutations in the ABHD5 gene can confirm a diagnosis of Chanarin-Dorfman syndrome. Scientific research articles, stored in databases such as PubMed and OMIM, provide additional information on the genetic causes and inheritance of the syndrome.

Advocacy and support groups, such as the Chanarin-Dorfman Syndrome Advocacy and Support Center, offer resources and information for individuals and families affected by the syndrome. ClinicalTrials.gov may also provide information on ongoing research studies and clinical trials related to Chanarin-Dorfman syndrome.

It is important for individuals with Chanarin-Dorfman syndrome to receive genetic counseling and testing, as well as regular monitoring of liver function. Genetic testing can also be beneficial for family members, as it can provide information on the likelihood of inheriting the syndrome.
