Chylomicron Retention Disease (CD) is a rare genetic condition characterized by the impaired transport of chylomicrons, which are particles that help in the absorption and transport of dietary fats. This condition is also known as Anderson’s disease or genetic deficiency of the SAR1B gene. CD is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene, one from each parent, to develop the disease.

Individuals with CD typically present with symptoms such as failure to thrive, malnutrition, and diarrhea, starting from early infancy. The decreased ability to transport chylomicrons leads to a buildup of these particles within the cells of the intestine, causing the characteristic features of the disease. Clinical manifestations of CD can vary in severity and can include fatty liver, hepatosplenomegaly, and anemia.

Diagnosis of CD is usually confirmed through genetic testing to identify mutations in the SAR1B gene. Additionally, laboratory tests may reveal elevated levels of triglycerides and chylomicrons in the blood. There is currently no specific treatment for CD, but management involves a low-fat diet and supplementation of fat-soluble vitamins.

Research on CD is ongoing, and resources such as OMIM, PubMed, and ClinicalTrials.gov provide additional information about the condition. Genetic studies and clinical trials are being conducted to better understand the disease and find potential treatments. Patient support groups and advocacy organizations, like the Center for Genomics and Rare Diseases at the University of Washington in Seattle, provide valuable resources and support for individuals and families affected by CD.

In conclusion, Chylomicron Retention Disease is a rare genetic condition characterized by impaired chylomicron transport. It is associated with mutations in the SAR1B gene and presents with a variety of clinical features. While there is currently no cure for CD, ongoing research and genetic testing provide hope for improved understanding and potential treatments in the future.

Frequency

Chylomicron retention disease (CD) is a rare genetic disorder. The exact frequency of CD is not known because it is a rare condition. However, research and studies have provided some information about its occurrence.

Patients, too, are unhappy with the care they receive during those brief interactions with their doctors. Healthcare communications company West Corporation reported that 25% of patients don’t feel that their provider cares about them as an individual and nearly 20% aren’t convinced their doctor is focused on improving their health – even though 93% of doctors strongly agree that patient satisfaction is important.

CD is an autosomal recessive condition, which means that it occurs when both copies of the SAR1B gene have mutations. The SAR1B gene provides instructions for making a protein that is involved in the movement of chylomicrons, which are particles that transport dietary fats throughout the body.

According to the Online Mendelian Inheritance in Man (OMIM) catalog, CD is associated with mutations in the SAR1B gene. There have been reported cases of CD from different parts of the world, including a study conducted in Seattle, USA.

Since CD is a rare disease, it is important for individuals with suspected CD to undergo genetic testing to confirm the diagnosis. This testing involves analyzing the SAR1B gene for mutations.

For more information about CD, individuals can seek support from various advocacy and support groups. These organizations provide resources and information about CD, other rare diseases, and genetic testing. Some of these resources include scientific articles, patient support groups, clinical trials, and genetic testing centers.

Additional information about CD and associated genes can be found on the OMIM catalog, as well as scientific articles published on PubMed.

Causes

Chylomicron retention disease (CD) is a rare genetic disorder caused by mutations in the SAR1B gene. SAR1B is responsible for the formation and secretion of chylomicrons, which are large particles that carry dietary fats from the intestine to other tissues in the body.

In individuals with CD, mutations in the SAR1B gene lead to decreased chylomicron secretion and retention within the cells of the intestine. This results in fat malabsorption and the accumulation of chylomicron remnants in the intestinal cells.

This rare disease is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated SAR1B gene, one from each parent, to develop the condition.

There is currently no cure for CD, but treatment options aim to manage the symptoms and complications associated with the disease. This may include dietary modifications, such as a low-fat diet, as well as the supplementation of certain vitamins and minerals.

Additional information on the causes of CD can be found in scientific articles and research resources. The Online Mendelian Inheritance in Man (OMIM) database provides a catalog of genes associated with rare genetic diseases, including SAR1B. The Seattle Children’s Hospital Genetic Disorders/Rare Diseases Information Center and advocacy organizations may also provide further information and support for patients and their families.

Learn more about the gene associated with Chylomicron retention disease

Chylomicron retention disease, also known as Anderson disease, is a rare genetic condition characterized by the impaired ability of the body to transport chylomicrons. Chylomicrons are fat particles that are responsible for the absorption and transport of dietary fats.

One gene associated with Chylomicron retention disease is the SAR1B gene. Mutations in the SAR1B gene can lead to the impaired functioning of the Sar1b protein, which is involved in the transport of chylomicrons from the endoplasmic reticulum to the Golgi apparatus.

Research has shown that individuals with Chylomicron retention disease have decreased levels of Sar1b protein, resulting in the accumulation of chylomicrons within the enterocytes of the small intestine.

To learn more about the SAR1B gene and its role in Chylomicron retention disease, you can explore the following resources:

  • OMIM: The Online Mendelian Inheritance in Man (OMIM) provides a comprehensive catalog of human genes and genetic disorders. You can find additional information about the SAR1B gene and its associated diseases on the OMIM website.

Inheritance

Chylomicron retention disease (also known as Anderson’s disease, or APOA5 deficiency) is a rare genetic condition. It is inherited in an autosomal recessive manner, which means that affected individuals inherit two copies of the mutated gene, one from each parent.

The gene mutation that causes chylomicron retention disease is known as SAR1B. This gene is responsible for the production of a protein that plays a key role in the transport of chylomicrons, which are particles that carry dietary fat throughout the body. The mutation in the SAR1B gene leads to decreased or absent function of this protein, resulting in the accumulation of chylomicrons within cells.

Individuals with chylomicron retention disease may experience a range of symptoms and features, including severe diarrhea, failure to thrive, and developmental delay. The severity and specific symptoms can vary widely between individuals. It is important to note that not all individuals with chylomicron retention disease will have all of these features.
