Fish-eye disease is a rare genetic condition caused by mutations in the LCAT gene. This gene encodes an enzyme called lecithin-cholesterol acyltransferase, which plays a key role in the metabolism of cholesterol. Mutations in the LCAT gene can lead to a decrease in the activity of this enzyme, resulting in the accumulation of cholesterol esters in various tissues of the body.

One of the main features of fish-eye disease is the cloudiness of the cornea, known as corneal opacities. These opacities can affect vision and lead to additional symptoms such as decreased visual acuity and sensitivity to light. The severity of these opacities can vary widely among affected individuals.

Fish-eye disease is inherited in an autosomal recessive manner, which means that individuals need to carry mutations in both copies of the LCAT gene to develop the condition. Individuals who carry only one copy of the mutated gene are typically unaffected, but they have a 50% chance of passing on the mutation to their children.

Diagnosis of fish-eye disease is based on clinical findings, genetic testing of the LCAT gene, and biochemical testing to measure the activity of the lecithin-cholesterol acyltransferase enzyme. Several resources are available for genetic testing, including the OMIM database, which provides information on the genes associated with rare diseases, and PubMed, which provides scientific articles and citation information on genetic diseases.

There is currently no specific treatment for fish-eye disease, but there are resources available for support and advocacy for individuals and families affected by this condition. Genetic counseling can help individuals understand the inheritance pattern and the risk of passing on the mutation to their children. Research on the functions of the LCAT gene and the underlying causes of fish-eye disease is ongoing, with the goal of developing targeted therapies in the future.

Frequency

Fish-eye disease is a rare genetic condition that affects the eyes. The frequency of this disease is very low, with only a few reported cases worldwide. The exact number is not known, as this condition is often underdiagnosed and underreported.

One of the most important and most popular changes to the health insurance landscape brought about by the passing of the Affordable Care Act was the prohibition against denying patients health insurance, or charging them more, if they had preexisting conditions. Research shows that 27% of Americans in the 18 to 64 age group have what would have been considered a “declinable medical condition” before the Affordable Care Act took effect, and in some regions, the percentage of patients with preexisting conditions rises to nearly four in 10, the Henry J. Kaiser Family Foundation

Scientific articles about Fish-eye disease can be found in medical databases such as PubMed and OMIM. These databases catalog various diseases and provide scientific resources for learning about rare conditions.

Genetic testing can support the diagnosis of Fish-eye disease by identifying mutations in the LCAT gene, which is associated with this condition. Mutations in the LCAT gene lead to the abnormal function of the enzyme lecithin-cholesterol acyltransferase, causing the accumulation of cholesterol and opacities in the cornea, leading to cloudiness in the eyes.

Patient advocacy groups and rare disease centers provide support and additional information for individuals with Fish-eye disease and other rare genetic diseases. They offer resources, genetic counseling, and connections to other patients affected by this condition.

It is important to note that Fish-eye disease is inherited in an autosomal recessive pattern, meaning that both parents must carry a mutated LCAT gene for the disease to be passed on to their children.

To learn more about the frequency and characteristics of Fish-eye disease, additional information can be found in scientific articles and references.

Causes

The Fish-eye disease is caused by mutations in the LCAT gene. The LCAT gene provides instructions for making the enzyme lecithin-cholesterol acyltransferase (LCAT), which is responsible for several functions in the body. These functions include removing cholesterol from cells and converting it into a form that can be removed from the body through bile and feces.

More than 30 mutations in the LCAT gene have been identified as causes of the Fish-eye disease. These mutations can lead to the production of a nonfunctional or partially functional version of the LCAT enzyme. As a result, cholesterol and other fats can build up in various tissues and organs, leading to the characteristic cloudiness of the corneas.

The Fish-eye disease is inherited in an autosomal recessive pattern, which means that both copies of the LCAT gene in each cell have mutations. Individuals who carry one copy of the mutated gene do not typically have any signs or symptoms of the condition.

Genetic testing can be used to identify specific LCAT gene mutations associated with Fish-eye disease. This testing can be done before birth or at any time during a person’s life. It is important to note that genetic testing is not available for all cases of Fish-eye disease, as some mutations in the LCAT gene have not yet been identified.

Additional resources for learning about Fish-eye disease and genetic testing are available from several organizations, including advocacy groups and research centers for rare diseases. These resources can provide more information on Fish-eye disease, its symptoms, genetic testing options, and support for patients and their families.

For more scientific information on the causes of Fish-eye disease, consultation of scientific articles and references such as those available on PubMed and OMIM can be helpful.

Learn more about the gene associated with Fish-eye disease

Fish-eye disease is a rare condition that causes cloudiness in the center of the cornea, which can lead to vision problems. It is caused by mutations in the LCAT gene.

The LCAT gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase. This enzyme is essential for the normal processing of cholesterol in the body.

Mutations in the LCAT gene lead to a decrease or absence of functional lecithin-cholesterol acyltransferase. This results in impaired cholesterol metabolism and the accumulation of cholesterol esters in various tissues, including the cornea, leading to the cloudiness seen in Fish-eye disease.

Fish-eye disease is a genetic condition, which means it is inherited from a person’s parents. Inheritance of this condition follows an autosomal recessive pattern, which means that both copies of the LCAT gene in each cell have mutations. Individuals who carry one mutated copy of the gene are called carriers and typically do not show signs or symptoms of the disease.

Inheritance

The Fish-eye disease is an inherited condition caused by mutations in the

lecithin-cholesterol acyltransferase (LCAT) gene. This gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase. This enzyme is responsible for converting free cholesterol into a storage form called cholesteryl ester, which is then transported in the blood attached to a protein. Mutations in the LCAT gene lead to a decrease in the activity of this enzyme, resulting in abnormal lipid metabolism.

The inheritance of Fish-eye disease follows an autosomal recessive pattern. This means that an affected individual has two copies of the mutated LCAT gene, one inherited from each parent. Individuals who carry only one mutated copy of the gene are known as carriers and are typically unaffected by the condition. When two carriers have children together, there is a 25% chance with each pregnancy of having an affected child, a 50% chance of having a child who is a carrier, and a 25% chance of having an unaffected child.

Mutations in the LCAT gene that cause Fish-eye disease can be detected through genetic testing. Genetic testing can confirm a diagnosis and can also be used for carrier testing in individuals with a family history of the condition. If both parents are carriers, prenatal testing or preimplantation genetic diagnosis may be available to determine the genetic status of a pregnancy.

Fish-eye disease is a rare genetic condition, with a frequency of less than 1 in 1 million individuals. The condition is listed in the Online Mendelian Inheritance in Man (OMIM) catalog, which provides information about genetic disorders and genes. The OMIM entry for Fish-eye disease includes references to scientific articles, both for more scientific information and for support and advocacy resources for patients and their families.
