Craniofacial-deafness-hand (CDH) syndrome is a rare genetic condition that affects the development of the craniofacial area, causing facial abnormalities, hearing loss, and hand deformities. It is also known as Nager syndrome, after the physician who first described it.

CDH syndrome is caused by mutations in the gene SF3B4. This gene provides instructions for making a protein that is involved in the splicing of other genes. Mutations in SF3B4 impair the normal splicing process, leading to the characteristic features of the syndrome.

People with CDH syndrome typically have underdeveloped cheekbones, a small jaw, and down-slanting eyelid openings. They may also have hearing loss, which can range from mild to profound. Hand abnormalities, such as missing thumbs or fused fingers, are common in individuals with CDH syndrome.

CDH syndrome is a rare condition, with an estimated frequency of less than 1 in 100,000 people. It 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.

Diagnosis of CDH syndrome is usually based on the characteristic clinical features. Genetic testing can be done to confirm the diagnosis and identify the specific mutations in the SF3B4 gene.

There is currently no cure for CDH syndrome, but treatment focuses on managing the symptoms and improving quality of life. This may include surgeries to correct facial abnormalities or hand deformities, hearing aids or cochlear implants for hearing loss, and speech therapy.

Part of the reason for these long wait times and short appointments is due to a nationwide shortage of physicians that is only getting worse. A report by the Association of American Medical Colleges predicts that, due to population growth and specifically growth of the elderly population, the physician shortfall in the U.S. could reach 121,300 by the year 2030.

Support and advocacy organizations, such as the CDH International – Center for Craniofacial Disorders, can provide resources and information for patients and their families. Additionally, scientific articles and references about CDH syndrome can be found in databases like OMIM (Online Mendelian Inheritance in Man) and PubMed.

For additional information and to learn more about CDH syndrome, gene testing, and associated conditions, it is recommended to consult with healthcare professionals and genetic counselors.

Frequency

The frequency of Craniofacial-deafness-hand syndrome is currently unknown. As of now, there have been very few reported cases of this condition in scientific literature and medical journals. It is considered to be a rare genetic disorder.

Due to its rarity, testing for Craniofacial-deafness-hand syndrome may not be readily available. Patients and their families may need to seek support and advocacy from genetic counseling centers, scientific organizations, and patient advocacy groups.

Additional information about the inheritance pattern and frequency of Craniofacial-deafness-hand syndrome can be found through various resources, such as:

• OMIM (Online Mendelian Inheritance in Man): A comprehensive catalog of human genes and genetic diseases. It provides detailed information on the genetic causes of various conditions, including Craniofacial-deafness-hand syndrome.
• PubMed: An online database of scientific articles and research papers. It can provide more information about the frequency and characteristics of the condition.
• The Human Gene Mutation Database: A resource that provides information on the genetic mutations associated with different genetic disorders.
• The National Organization for Rare Disorders (NORD): A patient advocacy organization that provides support and resources for individuals and families affected by rare diseases.

It is important to note that the frequency of Craniofacial-deafness-hand syndrome may be subject to change as more cases are reported and further research is conducted. Therefore, individuals seeking information or testing should consult with healthcare professionals and refer to the latest available resources for the most up-to-date information.

Causes

The craniofacial-deafness-hand syndrome is a rare genetic condition.

The OMIM database is a comprehensive resource for information on genetic conditions. The craniofacial-deafness-hand syndrome has an OMIM entry (OMIM ID: XXXX) which provides detailed information about the syndrome.

Genetic testing is available to confirm a diagnosis of craniofacial-deafness-hand syndrome. This testing can identify specific gene mutations associated with the condition.

Research studies have identified several genes that are linked to the craniofacial-deafness-hand syndrome. These genes play a role in the development of craniofacial tissues and hearing.

The specific causes of the craniofacial-deafness-hand syndrome are not yet fully understood. Research in this area is ongoing to learn more about the underlying genetic mechanisms and processes involved.

It is believed that the craniofacial-deafness-hand syndrome is inherited in an autosomal recessive manner. This means that an individual must inherit two copies of the mutated gene, one from each parent, in order to develop the condition.

Due to its rarity, there is limited scientific literature and advocacy resources available about the craniofacial-deafness-hand syndrome. Additional research and support are needed to further understand and address the needs of individuals affected by this condition.
