Van der Woude syndrome is a rare genetic condition that affects the development of the face. It is named after David P. van der Woude, who first described the syndrome in 1954. The syndrome is characterized by the presence of lower lip pits, which are small depressions or openings in the lower lip. In addition to the lip pits, people with Van der Woude syndrome may also have cleft lip and/or cleft palate.

Van der Woude syndrome is associated with mutations in the gene IRF6. This gene provides instructions for making a protein that is involved in the development of tissues throughout the body, including the face and limbs. Mutations in the IRF6 gene can cause the lower lip pits and cleft lip and/or palate that are characteristic of Van der Woude syndrome. Inheritance of the syndrome is autosomal dominant, which means that an affected individual has a 50% chance of passing the condition on to each of their children.

Testing for the gene mutation associated with Van der Woude syndrome can be done through genetic testing. This can provide an accurate diagnosis and help individuals and their families understand the inheritance pattern of the condition. Genetic testing can also be used to provide information about other associated features of Van der Woude syndrome, such as cognitive and other developmental delays.

Van der Woude syndrome is a rare condition, with a frequency estimated to be between 1 in 40,000 and 1 in 100,000 births. It is classified as a clefting disorder, which is a group of conditions characterized by the presence of a cleft lip and/or cleft palate. One of the most common features of Van der Woude syndrome is the presence of small depressions or openings in the lower lip, known as lower lip pits. These pits are also found in other rare genetic conditions, such as popliteal pterygium syndrome.

For more information about Van der Woude syndrome, you can visit the Online Mendelian Inheritance in Man (OMIM) catalog. The OMIM catalog is a comprehensive resource that provides information about the genetic basis of human diseases. It includes a description of the condition, as well as references to scientific articles and additional resources for further learning. Genetic advocacy organizations, such as the Genetic and Rare Diseases Information Center (GARD), also have resources available about Van der Woude syndrome and other rare genetic conditions.

Frequency

The frequency of Van der Woude syndrome is estimated to be approximately 1 in 40,000 to 1 in 100,000 individuals.

Denied health insurance claims are a major problem for patients in America. The Kaiser Family Foundation found that ACA marketplace plans denied about 17% of in-network claims in 2019.

Van der Woude syndrome is a rare genetic condition that is associated with mutations in the IRF6 gene. This gene is responsible for regulating cell growth, development, and differentiation. Genetic testing can be done to identify mutations in the IRF6 gene to confirm a diagnosis of Van der Woude syndrome.

While Van der Woude syndrome is a rare condition, it is the most common syndromic form of cleft lip and palate. It is characterized by the presence of cleft lip and/or cleft palate, as well as other features such as lower lip pits and pterygium of the eyes.

To learn more about Van der Woude syndrome and other related diseases, you can refer to the Online Mendelian Inheritance in Man (OMIM) database.

Causes

Van der Woude syndrome is caused by mutations in the IRF6 gene. This gene provides instructions for making a protein that is involved in the development and function of cells in the lips, mouth, and face. Mutations in this gene can disrupt the normal development of these tissues, leading to the characteristic features of Van der Woude syndrome, such as cleft lip and/or cleft palate.

Inheritance of the syndrome is autosomal dominant, which means that a person who has a mutation in one copy of the IRF6 gene has a 50% chance of passing the mutation on to each of their children.

Van der Woude syndrome can also be associated with mutations affecting other genes. Additional genes and factors may contribute to the varied signs and symptoms observed in individuals with this condition.

Van der Woude syndrome is considered a rare genetic condition, and its exact frequency in the general population is unknown.

For more information on the genetic causes of Van der Woude syndrome, you can refer to scientific articles available on platforms like PubMed or OMIM. These resources provide comprehensive information on the genes and diseases related to this condition.

Genetic testing can be performed to confirm a diagnosis of Van der Woude syndrome. This testing can identify mutations in the IRF6 gene or other associated genes. Genetic counseling is recommended for individuals and families considering testing, as it can provide information on the inheritance pattern and help in making informed decisions.
