Baraitser-Winter syndrome is a rare genetic condition that affects the development of multiple parts of the body. It was first described in 1988 by Baraitser and Winter, and since then, more information about this syndrome has been published on PubMed, a centralized database for scientific articles.
This syndrome is associated with mutations in certain genes that are involved in the migration of nerve cells during development. One of the main features of Baraitser-Winter syndrome is coloboma, which is a structural defect in the eye that affects the iris, retina, or optic nerve.
Other features of this condition include a high forehead, a broad nasal bridge, a small chin, and additional malformations in the brain and other parts of the body. The frequency of Baraitser-Winter syndrome is unknown, but it is considered to be a rare condition that affects both males and females.
If a patient is suspected to have Baraitser-Winter syndrome, genetic testing can be done to confirm the diagnosis. There is currently no specific treatment for this condition, but supportive care can help manage the symptoms and improve the overall quality of life for affected individuals.
More information about Baraitser-Winter syndrome can be found on resources such as OMIM (Online Mendelian Inheritance in Man) and the Genetic and Rare Diseases Information Center. Scientific articles and references can also provide further insights into the genetic causes and structural abnormalities associated with this rare syndrome.
Frequency
Baraitser-Winter syndrome is a rare genetic condition that affects the cytoskeleton, a network of proteins that provides structural support to the cells in the body. It is also known as the “coloboma, intellectual disability, and microcephaly” syndrome due to the presence of these common features in affected individuals. The exact frequency of the syndrome is not known, but it is considered to be a rare condition.
Baraitser-Winter syndrome is caused by mutations in various genes that are involved in the development and migration of cells in the body. These mutations can disrupt the normal functioning of the cytoskeleton and lead to the characteristic features of the syndrome.
Additional information about the frequency of Baraitser-Winter syndrome can be found in scientific publications. Some resources to learn more about this condition and genetic testing for it include PubMed, OMIM (Online Mendelian Inheritance in Man), and genetic advocacy organizations.

Causes
Baraitser-Winter syndrome is a rare genetic condition characterized by a variety of signs and symptoms. This syndrome is associated with mutations in the ACTB gene, which provides instructions for making a protein called β-actin. β-actin is an essential component of the cytoskeleton, which is the structural framework of cells.
Individuals with Baraitser-Winter syndrome typically have a range of features, including intellectual disability, distinctive facial features, and abnormalities of the eyes. Some affected individuals may also have malformations of the brain, heart, or other organs.
Baraitser-Winter syndrome is inherited in an autosomal dominant manner, which means that an affected individual has a 50% chance of passing the condition on to each of their children. The rarity of this syndrome is reflected in its frequency, which is currently unknown.
Genetic testing is available to confirm a diagnosis of Baraitser-Winter syndrome. This testing can detect mutations in the ACTB gene and is typically performed using a blood sample or a sample of DNA from another tissue. Additional resources for genetic testing and support can be found through organizations such as the Center for Human Genetics and the OMIM gene catalog.
Scientific articles and other sources provide more information about the genetic causes of Baraitser-Winter syndrome. PubMed, an online database of scientific articles, can be a valuable resource for finding relevant studies and references. Some other genetic conditions associated with mutations in the ACTB gene have also been identified, including coloboma of the eye.

Inheritance
The Baraitser-Winter syndrome, also called BRWS, is a rare genetic condition. It affects the structure and development of the body, including the brain. This syndrome was first described in 1988 by Baraitser and Winter.
This condition is inherited in an autosomal recessive manner, which means that both parents must carry a copy of the mutated gene in order for their child to be affected. If both parents are carriers, there is a 25% chance that their child will have the syndrome.
The genes associated with Baraitser-Winter syndrome are involved in the cytoskeleton and its regulation. One of the genes associated with this condition is called ACTB, which encodes the β-actin protein. Mutations in this gene can affect the stability and function of the cytoskeleton, leading to the symptoms of the syndrome.
Some of the characteristics and symptoms of Baraitser-Winter syndrome include intellectual disability, developmental delay, distinctive facial features, epilepsy, and eye abnormalities such as coloboma. However, the severity and combination of symptoms can vary widely among affected individuals.
Genetic testing can be used to confirm the diagnosis of Baraitser-Winter syndrome. Testing may include sequencing of specific genes associated with the condition or more comprehensive testing methods such as whole exome sequencing.
