Vohwinkel syndrome, also known as Vohwinkel syndrome with mutilating keratoderma, is a rare genetic condition characterized by the presence of tight skin on the fingers and toes. The syndrome is inherited in an autosomal dominant pattern, meaning that an affected individual has a 50% chance of passing the condition on to their children.
The condition was first described by Vohwinkel in 1928 and has since been extensively studied and documented by researchers. It is listed in various medical databases such as PubMed and OMIM, which provide scientific articles and resources for further information.
Vohwinkel syndrome is caused by mutations in the GJB2 gene, which is responsible for the production of proteins that form gap junctions in the skin’s epidermis. These proteins play a crucial role in the function of the skin, and alterations in their structure can lead to the formation of the characteristic tight skin and other associated symptoms.
Classic symptoms of Vohwinkel syndrome include palmoplantar keratoderma (thickened skin on the palms and soles), hearing loss, and the presence of star-like waves on the palms and soles. The condition can also be associated with other disorders such as ichthyotic and mutilating disorders.
Testing for Vohwinkel syndrome can be done through genetic testing, which can identify mutations in the GJB2 gene. This information can be valuable for the patient and their healthcare team in terms of understanding the condition and providing appropriate care.
While Vohwinkel syndrome is a rare condition, knowledge about the disease and its genetic causes is continually growing. This provides support for affected individuals and their families, as well as opportunities for further research and better treatment options.
In studies, the artificial intelligence (AI) technology used in some online health services for preliminary screening before connecting patients with a doctor actually outperformed real physicians in terms of reaching an accurate diagnosis, CNN AI technology correctly diagnosed conditions in 81% of patients, compared to a 72% average for accurate diagnoses among real physicians over a five-year period.
More information about Vohwinkel syndrome and other genetic disorders can be found in the scientific literature and medical resources available from various genetic centers and organizations.
Vohwinkel syndrome is a very rare genetic disorder that affects the skin, causing the formation of tight waves in the epidermis. It is also known as palmoplantar keratoderma with constriction bands or palmoplantar keratoderma with pseudoainhum. The syndrome is caused by mutations in the GJB2 gene, which provides instructions for making a protein called connexin 26. These mutations alter the function of connexin 26 and lead to the classic symptoms of Vohwinkel syndrome.
The frequency of Vohwinkel syndrome is not well documented, but it is considered to be a rare condition. The exact number of cases worldwide is unknown, but it is estimated to affect less than 1 in 1,000,000 people. The condition has been reported in various populations and has no specific gender or ethnic predilection.
Vohwinkel syndrome is often inherited in an autosomal dominant pattern, which means that an affected person has a 50% chance of passing the condition on to each of their children. However, in some cases, the syndrome can also be caused by de novo mutations, which are not inherited from either parent.
For additional information about the frequency and inheritance of Vohwinkel syndrome, you can refer to scientific articles and resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources provide more detailed information about the disease, its genetic causes, and testing options.
The Vohwinkel Syndrome Support and Advocacy Center is another valuable resource for patients and families affected by this condition. The center offers support, information, and resources for individuals with Vohwinkel syndrome and other related disorders.

Vohwinkel syndrome is a rare genetic disorder that is caused by mutations in the GJB2 gene. This gene is responsible for encoding a protein called connexin 26, which plays a critical role in the function of cells in the epidermis, the outermost layer of the skin.
In some cases, Vohwinkel syndrome can also be caused by mutations in other genes, such as GJB6 and LOR. These mutations can alter the function of proteins involved in the formation of the epidermis and can result in the characteristic symptoms of the syndrome.
The frequency of Vohwinkel syndrome is not well known, but it is considered to be a rare condition. The exact number of cases is difficult to determine, as the syndrome is often misdiagnosed or underdiagnosed. Additionally, the syndrome can present with varying degrees of severity, making it difficult to identify all cases.
The inheritance pattern of Vohwinkel syndrome is autosomal dominant, which means that an affected individual has a 50% chance of passing the condition on to each of their children. However, some cases of the syndrome can also occur sporadically, without a family history of the disorder.
Diagnosis of Vohwinkel syndrome is usually based on the characteristic symptoms, such as palmoplantar keratoderma (thickening of the skin on the palms of the hands and soles of the feet), hearing loss, and other skin abnormalities. Genetic testing can also be performed to confirm the diagnosis and identify the specific mutations associated with the syndrome.
There is currently no cure for Vohwinkel syndrome, and treatment focuses on managing the symptoms and supporting the patient’s overall well-being. This may include regular skin care, hearing aids for those with hearing loss, and support from advocacy and support groups.
For more information about the causes of Vohwinkel syndrome, scientific articles and resources can be found in databases such as PubMed and Online Mendelian Inheritance in Man (OMIM), as well as through genetic testing and consultation with a medical geneticist.
Learn more about the genes associated with Vohwinkel syndrome
Vohwinkel syndrome, also known as mutilating keratoderma with ichthyotic features, is a rare genetic disorder characterized by palmoplantar keratoderma. It belongs to a group of disorders known as the palmoplantar keratodermas.
Vohwinkel syndrome is caused by mutations in the GJB2 and GJB6 genes. Mutations in the GJB2 gene are the most common cause of Vohwinkel syndrome, accounting for up to 80% of cases. The GJB6 gene is also associated with this condition.
These two genes provide instructions for making proteins that are part of gap junctions, which are channels that allow cells to communicate with each other. Mutations in these genes disrupt the function of the proteins, impairing the formation of functional gap junctions. This leads to the signs and symptoms of Vohwinkel syndrome.
The loss of gap junction function is thought to cause the tight adherence between the skin cells of the palms and soles seen in Vohwinkel syndrome. This tight adherence results in thickening of the skin and the development of the characteristic scales and painful cracks.
Vohwinkel syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.
Genetic testing is available to confirm a diagnosis of Vohwinkel syndrome. Additional testing, such as electron microscopy and immunohistochemistry, may be done to support the diagnosis.
There are resources available for patients and their families to learn more about Vohwinkel syndrome, including the Online Mendelian Inheritance in Man (OMIM) catalog and scientific articles available through PubMed. Genetic testing centers and advocacy organizations for genetic diseases can also provide information and support.
Vohwinkel syndrome is an inherited genetic disease. It belongs to a group of diseases known as ichthyotic disorders, which cause dry and scaly skin. The inheritance of Vohwinkel syndrome is autosomal dominant, which means that only one copy of the mutated gene is needed to develop the disease.
The classic form of Vohwinkel syndrome is caused by mutations in the GJB2 gene, which is responsible for the production of a protein called connexin 26. This protein plays a crucial role in the normal functioning of the epidermis, the outermost layer of the skin.
Mutations in the GJB2 gene result in the production of a mutant connexin 26 protein that disrupts the normal formation of tight junctions between skin cells. This leads to the characteristic symptoms of Vohwinkel syndrome, such as palmoplantar keratoderma and mutilating skin lesions.
Genetic testing provides a way to confirm the diagnosis of Vohwinkel syndrome and learn more about the specific genetic cause. There are several resources, such as Online Mendelian Inheritance in Man (OMIM) and the Vohwinkel Syndrome Research Center, that support genetic testing for this condition and provide information about the known genes and mutations associated with Vohwinkel syndrome.
In addition to the GJB2 gene, other genes have been found to be associated with Vohwinkel syndrome through genetic testing. These include the GJB4 and LOR genes, which encode proteins involved in the normal function of the epidermis.
Genetic testing can also be helpful in cases where the diagnosis of Vohwinkel syndrome is uncertain or when a patient has features that overlap with other conditions, such as deafness or mutilans-like phenotype. Genetic testing and counseling can provide important information about the inheritance pattern and recurrence risk for individuals and families affected by Vohwinkel syndrome.
