The MSX1 gene, also known as the “Witkop syndrome gene,” is a genetic variant responsible for certain conditions and disorders. It is one of the many genes listed in genetic databases and registries, such as OMIM and the Genetic Testing Registry, which provide additional information and resources related to this gene and its associated diseases.

MSX1 gene changes have been found to be associated with selective tooth agenesis and cleft palate, among other conditions. Scientific articles and studies on this gene and its associated disorders can be found on PubMed, a vast database of biomedical literature.

The mutation in the MSX1 gene disrupts normal development, leading to clefting and various changes in the teeth, palate, and toenails. Testing for variant changes in this gene can be done through genetic tests, which are available for individuals suspected to have related disorders. The Vastardis et al. study published in PubMed provides extensive information on the genetic changes in the MSX1 gene and their association with clefting and tooth abnormalities.

For more information on the MSX1 gene and related health conditions, various resources such as the Online Mendelian Inheritance in Man (OMIM) and Genetic Testing Registry provide references, articles, and catalog-like information.

This introduction aims to provide a brief overview of the significance of the MSX1 gene and its role in various genetic disorders. Further research and studies are needed to fully understand the functions and implications of this gene.

Health Conditions Related to Genetic Changes

Genetic changes or mutations in the MSX1 gene can lead to various health conditions. Here is a list of some conditions associated with genetic changes in the MSX1 gene:

Americans see their primary care doctors less often than they did a decade ago. Adults under 65 made nearly 25% fewer visits to primary care providers in 2016 than they did in 2018, according to National Public Radio. In the same time period, the number of adults who went at least a year without visiting a primary care provider increased from 38% to 46%.

• Orofacial Clefting: Genetic changes in the MSX1 gene can disrupt the development of the palate, leading to orofacial clefting. This condition is characterized by a gap or split in the lip and/or palate.

• Oligodontia: Some genetic changes in the MSX1 gene are associated with oligodontia, a condition characterized by the absence of several teeth.

• Toenail Hypoplasia: Certain genetic changes in the MSX1 gene also affect the development of toenails, leading to toenail hypoplasia.

• Wolf-Hirschhorn Syndrome: In rare cases, genetic changes in the MSX1 gene are linked to Wolf-Hirschhorn syndrome, a chromosomal disorder that affects many parts of the body.

• Witkop Syndrome: Genetic changes in the MSX1 gene can be responsible for Witkop syndrome, a condition characterized by tooth abnormalities and other dental defects.

Genetic testing for changes in the MSX1 gene can be used to diagnose or confirm the presence of these health conditions. The following resources may provide more information on the health conditions related to genetic changes in the MSX1 gene:

• Online Mendelian Inheritance in Man (OMIM) catalog: OMIM is a database that provides detailed information on genetic disorders and related genes. It can be accessed at https://omim.org.

Wolf-Hirschhorn syndrome

Wolf-Hirschhorn syndrome is a rare genetic disorder caused by a deletion of a portion of chromosome 4. It is characterized by distinctive facial features, intellectual disability, delayed growth and development, and seizures.

Individuals with Wolf-Hirschhorn syndrome typically have a unique facial appearance, including a high forehead, wide-set eyes, a broad nose, a short philtrum, and a cleft lip or palate. They may also have other physical abnormalities, such as heart defects, skeletal anomalies, and hearing loss.

The syndrome is named after U.S. researchers Ute Wolf and Kurt Hirschhorn, who first described the condition in 1961. It is sometimes referred to by other names, including 4p- syndrome and Pitt-Rogers-Danks syndrome.

Wolf-Hirschhorn syndrome is caused by a deletion of genes on the short (p) arm of chromosome 4. One of the genes affected by this deletion is the MSX1 gene, which plays a role in the development of the palate and teeth. Changes in the MSX1 gene are also associated with cleft lip and palate and other dental abnormalities.

The diagnosis of Wolf-Hirschhorn syndrome is typically made based on clinical features and confirmed by genetic testing. Additional tests may be performed to evaluate and manage the specific features and associated conditions in each individual.

Information about Wolf-Hirschhorn syndrome can be found in various scientific databases and online resources including OMIM (Online Mendelian Inheritance in Man) and PubMed. These sources provide detailed information on the genetic changes, clinical features, and management of the syndrome.

Genetic testing is available to detect deletions or changes in the MSX1 gene and other genes associated with cleft lip and palate and related disorders. This testing can help confirm the diagnosis and provide information for recurrence risk counseling.

The Wolf-Hirschhorn Syndrome International Registry (WHSIR) is a resource for individuals and families affected by the condition. The registry collects information about individuals with Wolf-Hirschhorn syndrome and provides support and resources for affected individuals, families, and healthcare professionals.

In addition to the MSX1 gene, several other genes have been associated with cleft lip and palate and related conditions. These include the TBX22 gene, the IRF6 gene, and the PVRL1 gene, among others. Genetic changes in these genes disrupt the development of the palate and can lead to cleft lip and palate.

Variant databases, such as the Vastardis database, catalog known genetic variants in these genes. Scientific articles and other resources provide further information on the role of these genes in cleft lip and palate and related conditions.
