The TCOF1 gene, also known as treacle, is a gene associated with Treacher Collins syndrome (TCS), a genetic disorder that affects the development of facial bones and tissues. TCS is characterized by a variety of craniofacial abnormalities, including coloboma of the lower eyelid.

The TCOF1 gene provides instructions for making a protein called treacle, which plays a critical role in the early development of facial structures. Mutations in the TCOF1 gene can lead to a reduction in the production of treacle or the production of an altered form of the protein. These changes disrupt the normal development of the face, resulting in the characteristic features of TCS.

Scientific articles, health databases, and genetic testing resources list TCOF1 and TCOF1 gene variant as related to Treacher Collins syndrome. Additional information on these conditions and related genes can be found in databases, such as the OMIM, PubMed, and the Treacher Collins syndrome registry. Various genetic tests and gene catalog listings are available for the testing of TCOF1 gene and other related genes.

In conclusion, the TCOF1 gene, also known as treacle, is associated with Treacher Collins syndrome, a genetic disorder that affects facial development. Mutations in this gene can lead to a variety of craniofacial abnormalities and coloboma of the lower eyelid. Additional information, genetic testing resources, and scientific articles can be found in various databases and registries related to TCOF1 and Treacher Collins syndrome.

Health Conditions Related to Genetic Changes

Genetic changes in the TCOF1 gene can lead to various health conditions. Some of these conditions are listed in this catalog, while others may not be included. Genetic changes in the TCOF1 gene are primarily associated with Treacher Collins syndrome. Treacher Collins syndrome is a rare genetic disorder that affects the development of the bones and tissues in the face.

In addition to Treacher Collins syndrome, other health conditions related to genetic changes in the TCOF1 gene include coloboma. Coloboma is an eye abnormality that is present at birth and can affect any part of the eye. The specific types of coloboma related to TCOF1 gene changes have been documented in scientific articles and databases such as OMIM and PubMed.

Just under half – 49% – of Americans get their health insurance through their employer, according to the Henry J. Kaiser Family Foundation. Another 19% of Americans are insured under Medicaid, 14% under Medicare, seven% under non-group plans and two% under other public insurers, while nine% of U.S. citizens remain uninsured.

Testing for genetic changes in the TCOF1 gene, also known as treacle, can be done through various genetic testing resources and laboratories. The TCOF1 gene is one of the genes that is commonly tested in individuals suspected of having Treacher Collins syndrome. Testing for TCOF1treacle genetic changes can help provide additional information for diagnosis and management of the condition.

Treacher Collins syndrome

Treacher Collins syndrome, also known as Treacher Collins-Franceschetti syndrome or mandibulofacial dysostosis, is a genetic disorder that affects the development of bones and other tissues in the face. It is named after Edward Treacher Collins, the English ophthalmologist who first described the condition in 1900.

This syndrome is caused by mutations in the TCOF1 gene, which provides instructions for making a protein called treacle. Treacle is involved in the early development of facial structures during embryonic development. Mutations in the TCOF1 gene lead to a reduction or loss of functional treacle, resulting in the characteristic facial features seen in Treacher Collins syndrome.

The main features of Treacher Collins syndrome include downward slanting eyes, coloboma (a gap or hole in structures of the eye), underdeveloped zygomatic bones (cheekbones), hypoplastic mandible (underdeveloped lower jaw), and malformed external ears. These facial abnormalities can vary in severity and may affect both sides of the face symmetrically or asymmetrically.

In addition to facial characteristics, Treacher Collins syndrome can also cause hearing loss due to defects in the middle ear structures. Other problems that may occur include cleft palate, dental problems, and breathing difficulties. The severity of these additional features can vary widely among individuals with the syndrome.

Treacher Collins syndrome is a rare condition, with an estimated frequency of 1 in 50,000 live births. It is inherited in an autosomal dominant manner, which means that a person only needs to inherit one copy of the mutated TCOF1 gene from one parent to develop the syndrome. However, most cases are due to new mutations in the gene and occur in people with no family history of the syndrome.

Diagnosis of Treacher Collins syndrome is based on the characteristic physical features and may be confirmed through genetic testing. Genetic testing can detect changes in the TCOF1 gene or other related genes associated with similar conditions. These tests can be performed using a variety of methods, including sequencing of the gene, deletion/duplication testing, and other specialized techniques.

There are several resources available for more information on Treacher Collins syndrome. The Online Mendelian Inheritance in Man (OMIM) database provides a comprehensive catalog of genetic conditions and associated genes. The OMIM entry for Treacher Collins syndrome (OMIM #154500) includes a summary of the condition, genetic testing information, and references to scientific articles. The GeneTests website offers additional information on testing options and laboratories that perform genetic testing for Treacher Collins syndrome.

Other resources include patient support groups and registries, such as the Treacher Collins Syndrome Foundation and the Treacher Collins Registry. These organizations provide support and information for individuals affected by the syndrome and their families. They may also fund research efforts to better understand the condition and develop improved treatments.

In conclusion, Treacher Collins syndrome is a rare genetic disorder characterized by facial abnormalities and potentially other health problems. Genetic testing is available to confirm the diagnosis and identify specific changes in the TCOF1 gene or other related genes. Resources such as OMIM, GeneTests, and patient support groups can provide additional information, resources, and support for individuals and families affected by this syndrome.

Coloboma

A coloboma is a birth defect where there is an incomplete closure of a structure in the eye, causing a gap or hole. It can occur in different parts of the eye, including the iris, retina, choroid, or optic disc. Coloboma is often associated with vision impairment or blindness in the affected eye.

The treacle protein, encoded by the TCOF1 gene, is involved in the development of several structures in the face and eyes. Mutations in the TCOF1 gene can lead to Treacher Collins syndrome, which is characterized by coloboma, facial abnormalities, and hearing loss.

Additional resources on coloboma and related conditions can be found through the following:

• The National Organization for Rare Disorders (NORD) provides information on Treacher Collins syndrome and coloboma.
• The Genetic and Rare Diseases Information Center (GARD) has resources on Treacher Collins syndrome and coloboma.
• The Online Mendelian Inheritance in Man (OMIM) database contains information on the TCOF1 gene and Treacher Collins syndrome.
• The Human Gene Mutation Database (HGMD) lists genetic variant changes associated with Treacher Collins syndrome and coloboma.
• PubMed, a database of scientific articles, has research papers on coloboma and the TCOF1 gene.

This information can be used for early testing and diagnosis of coloboma and related conditions. Genetic testing for mutations in the TCOF1 gene can help confirm a diagnosis of Treacher Collins syndrome. Reduction of vision impairment and blindness through early intervention and treatment is possible with these resources.
