Lattice corneal dystrophy type II is a rare genetic condition that affects the cornea, the clear front layer of the eye. It is typically caused by mutations in the TGFBI gene, which is responsible for producing a protein called beta-2 microglobulin. This protein accumulates in the layers of the cornea, forming abnormal deposits called amyloid fibrils. These deposits can lead to vision problems, including difficulty seeing clearly and recurrent corneal erosions.

The frequency of lattice corneal dystrophy type II is not well-known, but it is considered to be a rare condition. It has been reported in various populations throughout the world, with genetic studies suggesting that it may be more common in certain regions. The condition is also associated with other diseases, such as lattice corneal dystrophy type I and an inherited form of cranial neuropathy.

There are several scientific resources and databases that provide additional information about lattice corneal dystrophy type II. The OMIM (Online Mendelian Inheritance in Man) database provides detailed information about the genetic basis of the condition, including inheritance patterns and associated genes. PubMed, a database of scientific articles, also contains a wealth of information about lattice corneal dystrophy type II, including case reports, genetic testing guidelines, and studies on treatment options.

For patients and families affected by lattice corneal dystrophy type II, there are also support and advocacy organizations that can provide resources and information. These organizations may offer support groups, educational materials, and assistance in finding healthcare providers with experience in treating the condition. Additionally, genetic testing laboratories often provide testing and counseling services for patients with lattice corneal dystrophy type II.

In conclusion, lattice corneal dystrophy type II is a rare genetic condition that causes abnormal deposits in the cornea, leading to vision problems.

Scientific resources such as OMIM and PubMed provide additional information about the condition, and support and advocacy organizations offer resources for affected individuals and their families.

Frequency

Lattice corneal dystrophy type II is a rare genetic condition. It is caused by mutations in the gelsolin gene. The condition is inherited in an autosomal dominant manner, which means that individuals with a single copy of the mutated gene have a 50% chance of passing it on to each of their children.

Long wait times are often cited as a downfall of universal healthcare systems, but wait times in America have reached a new high, too. The average time to make a physician appointment as a new patient in 15 major U.S. cities is now 24 days, up 30% in just 3 years (2014 to 2018) according to physician recruiting firm Merritt Hawkins.

This type of corneal dystrophy is more common in individuals of Finnish descent, with an estimated prevalence of 1 in 50,000 to 1 in 100,000 people in Finland. It is also found in other populations, but at a much lower frequency.

Patients with lattice corneal dystrophy type II typically experience vision problems and may have difficulty with glare and sharpness of vision. The condition can also lead to recurrent corneal erosions, which can cause pain and discomfort.

Scientific articles and other resources with information about lattice corneal dystrophy type II and its associated conditions can be found in databases such as PubMed and OMIM. Genetic testing can be done to confirm a diagnosis of lattice corneal dystrophy type II and to identify the specific mutation in the gelsolin gene.

For additional support and information, there are advocacy organizations and patient support groups that can provide resources and connect individuals affected by lattice corneal dystrophy type II. These groups may also provide information about other rare diseases associated with gelsolin-related amyloidosis, such as cranial neuropathy.

Causes

Lattice corneal dystrophy type II, also known as familial amyloidosis gelsolin-related, is a rare genetic condition. It is caused by mutations in the gene known as gelsolin (GSN).

This condition follows an autosomal dominant inheritance pattern, which means that an affected individual only needs to inherit one copy of the mutated gene from either parent to develop the disease.

The frequency of lattice corneal dystrophy type II is rare. It is most commonly found in individuals of Danish descent, but cases have been reported in different populations worldwide.

In individuals with lattice corneal dystrophy type II, amyloid deposits build up in the cornea, the clear front surface of the eye. These deposits occur in the layers of the cornea, leading to the characteristic lattice-like appearance when viewed under a microscope.

Some individuals with lattice corneal dystrophy type II may also develop amyloidosis, which is the abnormal buildup of amyloid proteins in various organs and tissues of the body.

In addition to corneal manifestations, this condition has been associated with other diseases such as cranial neuropathy and difficulty swallowing.

A genetic test can confirm the diagnosis of lattice corneal dystrophy type II by identifying mutations in the gelsolin gene.

For more information about this condition, including genetic testing and support resources, you can visit the Online Mendelian Inheritance in Man (OMIM) database, which provides comprehensive and up-to-date scientific articles on genetic diseases.

Inheritance

Lattice corneal dystrophy type II (LCDII) is an inherited eye condition that affects the cornea, which is the clear front surface of the eye. It is also associated with gelsolin-related amyloidosis, a condition that affects multiple organ systems including the nerves (neuropathy).

Both LCDII and gelsolin-related amyloidosis are caused by mutations in the genes associated with gelsolin (GSN). These mutations lead to the abnormal buildup of amyloid protein in various parts of the body, including the cornea.

LCDII and gelsolin-related amyloidosis have an autosomal dominant inheritance pattern, which means that individuals with one copy of the mutated gene are typically affected by the condition. In rare cases, individuals with two copies of the mutated gene may develop a more severe form of the condition.

Genetic testing can be performed to confirm a diagnosis of LCDII or gelsolin-related amyloidosis in individuals with symptoms or a family history of the condition. This testing is available through specialized genetic testing centers.

In addition to genetic testing, a thorough clinical evaluation, including a detailed medical history and physical examination, is typically conducted to assess the severity and progression of the condition.

Support and advocacy organizations, such as the Lattice Corneal Dystrophy International Consortium and the Amyloidosis Foundation, can provide more information and resources for patients and their families.
