Complete LCAT deficiency

Complete LCAT deficiency

Complete LCAT deficiency, also known as familial lecithin-cholesterol acyltransferase (LCAT) deficiency, is a genetic condition that affects the functions of the LCAT gene. This rare genetic disorder can lead to various health problems and complications.

Complete LCAT deficiency is caused by mutations in the LCAT gene, which is responsible for producing the enzyme lecithin-cholesterol acyltransferase. This enzyme plays a crucial role in the metabolism of lipids, specifically in the formation of high-density lipoprotein (HDL) particles. HDL particles are responsible for carrying cholesterol from tissues back to the liver for further processing and elimination.

Individuals with complete LCAT deficiency have malfunctioning LCAT enzymes, which result in the inability to effectively process and eliminate cholesterol. This leads to the buildup of cholesterol and other lipids in various tissues, including the corneas and kidneys. These lipid deposits can cause a range of symptoms and complications, including vision problems, kidney dysfunction, and other related health issues.

Research and studies on complete LCAT deficiency are ongoing. Scientists and researchers are studying the genetic inheritance patterns, functional impact of different mutations, and potential treatment options for this condition. Several resources, such as scientific articles, clinical trial databases, and advocacy organizations, provide information and support for patients, families, and healthcare professionals interested in learning more about complete LCAT deficiency.

Frequency

Complete LCAT deficiency, also known as Lecithin:cholesterol acyltransferase deficiency, is a rare genetic condition that affects the function of the LCAT gene. It is estimated to occur in approximately 1 in 1,000,000 individuals worldwide.

The condition was first described in the scientific literature in 1967 by Nakayama et al. and is associated with the accumulation of cholesterol ester deposits in various tissues, including the corneas, leading to visual impairments.

Complete LCAT deficiency is inherited in an autosomal recessive manner, which means that an individual must inherit two copies of the defective gene (one from each parent) in order to develop the condition.

Genetic testing can be used to confirm a diagnosis of complete LCAT deficiency. This testing can identify mutations in the LCAT gene that are associated with the condition.

Further studies and research are ongoing to better understand the frequency, genetic basis, associated diseases, and clinical trials for the condition. Learn more about LCAT deficiency and its functions in the LCAT gene.

Causes

The main cause of Complete LCAT deficiency is genetic inheritance. It is a rare condition that affects the function of the LCAT gene. Complete LCAT deficiency is associated with mutations in the LCAT gene, which lead to a lack or absence of LCAT enzyme activity. This enzyme is responsible for the production of high-density lipoproteins (HDL) in the body.

Complete LCAT deficiency has an autosomal recessive inheritance pattern, which means both copies of the LCAT gene must have mutations for the condition to develop. If a person has only one mutated copy of the gene, they are considered carriers and do not typically experience symptoms of the condition.

The frequency of Complete LCAT deficiency is extremely rare, with only a few documented cases reported in scientific literature. Research and studies on this condition are limited, and more genetic information is needed to fully understand the causes and functions of the LCAT gene.

Studies published in PubMed have explored the various genetic mutations associated with Complete LCAT deficiency, such as the Nakayama mutation. These studies have also examined the effects of the condition on different tissues and organs, including the corneas and blood vessels.

Advocacy groups and resources like OMIM (Online Mendelian Inheritance in Man) provide information and support for patients and families affected by Complete LCAT deficiency. They offer genetic testing, clinical trial information, and additional references for further research on this rare genetic disease.

Learn more about the gene associated with Complete LCAT deficiency

Complete LCAT deficiency is a rare genetic condition that affects the LCAT gene. LCAT, or lecithin-cholesterol acyltransferase, is an enzyme responsible for the metabolism of lipids, including cholesterol, in various tissues.

When the LCAT gene is defective or mutated, it can lead to the development of Complete LCAT deficiency. This condition is characterized by the accumulation of lipids, specifically cholesterol, in various tissues of the body.

Studies have shown that this genetic condition is inherited in an autosomal recessive manner, meaning that both parents must carry a copy of the defective gene in order for their child to be affected. The frequency of Complete LCAT deficiency is very low, and it is considered a rare condition.

Genetic testing can be done to confirm the diagnosis of Complete LCAT deficiency. This involves analyzing the patient’s DNA for any mutations or defects in the LCAT gene. Additional tests, such as blood lipid profiles and imaging studies, may also be done to evaluate the extent of lipid deposits in the body.

There are several resources available that provide more information about Complete LCAT deficiency and its associated gene. One such resource is the Online Mendelian Inheritance in Man (OMIM) database, which catalogs genetic diseases and their associated genes. The OMIM entry for LCAT deficiency provides detailed information on the genetic cause, clinical features, and management of this condition.

Other scientific articles and research studies can also be found on PubMed, a database of scientific publications. PubMed contains numerous articles on LCAT deficiency, its genetic causes, and potential treatment options.

Inheritance

The inheritance pattern of Complete LCAT deficiency is autosomal recessive. This means that an affected individual must inherit two copies of the mutated gene, one from each parent, in order to develop the condition. If both parents are carriers of a single copy of the mutated gene, they have a 25% chance of having a child with Complete LCAT deficiency with each pregnancy.

To diagnose Complete LCAT deficiency, genetic testing can be performed to identify mutations in the LCAT gene. This gene provides instructions for making the Lecithin-Cholesterol Acyltransferase (LCAT) enzyme. Mutations in the LCAT gene can lead to a deficiency or complete absence of functional LCAT enzyme, which affects its ability to perform its normal functions.

Complete LCAT deficiency is a rare genetic condition. Therefore, it is important for clinicians and patients to have access to resources and support. There are several databases and platforms available to learn more about this condition and find support.
