The Mowat-Wilson syndrome is a rare genetic condition caused by mutations in the ZEB2 (ZFHX1B) gene. It was first described in 1998 by Mowat et al. and Wilson et al. The exact frequency of the syndrome is unknown, but it is estimated to occur in approximately 1 in 50,000 to 1 in 100,000 live births.

Additional articles and scientific resources are available for people who want to learn more about this rare syndrome. The Mowat-Wilson Syndrome Foundation, the Mowat-Wilson Syndrome Research Center, and other advocacy and support groups provide free information, resources, and support for individuals and families affected by the syndrome.

The Mowat-Wilson syndrome is associated with a variety of clinical features. Some of the most common symptoms include intellectual disability, distinctive facial features, delayed development, seizures, congenital heart defects, and gastrointestinal problems such as constipation. However, the phenotype can vary among individuals with the syndrome, and not all features may be present in every patient.

The average length of the portion of a doctor appointment in which the patient actually sees the doctor is up from previous years, rising by about 12 seconds per year, according to Reuters. However, 60% of physicians report dissatisfaction with the amount of time they spend with their patients, athenaInsight Many doctors now spend more time on paperwork than seeing patients, and a primary care physician who spends 5 minutes of face-to-face time with a patient will spend another 19.3 minutes, on average, working on that patient’s electronic health records (EHRs).

Genetic testing is available to confirm the diagnosis of Mowat-Wilson syndrome. Testing can detect mutations in the ZEB2 gene, which are the underlying cause of the syndrome. In some cases, genetic testing may also be able to identify other genes for rare diseases with similar features to Mowat-Wilson syndrome.

Causes

Mowat-Wilson syndrome (MWS) is a rare genetic condition that is caused by mutations in the ZEB2 gene. The ZEB2 gene is also known by other names, including SIP1 and ZFHX1B.

These mutations in the ZEB2 gene are associated with a wide range of clinical features and medical problems. The ZEB2 gene provides instructions for making a protein that is involved in the development and function of many different tissues and organs in the body.

Mutations in the ZEB2 gene can lead to a variety of symptoms, including intellectual disability, distinctive facial features, and developmental delays. Other features commonly seen in people with Mowat-Wilson syndrome include heart defects, Hirschsprung disease (a condition that affects the large intestine and causes severe constipation), and problems with the kidneys and urinary tract.

The inheritance pattern of Mowat-Wilson syndrome is autosomal dominant, which means that a person only needs to inherit one altered copy of the ZEB2 gene to develop the condition. Most cases of Mowat-Wilson syndrome are not inherited from a parent, but occur as new mutations in the ZEB2 gene.

Testing for mutations in the ZEB2 gene is available and can confirm a diagnosis of Mowat-Wilson syndrome in individuals with the characteristic clinical features. It is important to note that not everyone with Mowat-Wilson syndrome will have a mutation in the ZEB2 gene, as additional genes have also been associated with a similar phenotype.

For more information about the genetic causes of Mowat-Wilson syndrome, resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed can provide access to scientific articles and references.

Support and advocacy organizations, such as the Mowat-Wilson Syndrome Foundation and the Mowat-Wilson Syndrome Center at Baylor College of Medicine, can also provide additional information and resources for patients and families affected by Mowat-Wilson syndrome.
