Bannayan-Zonana syndrome

From WikiMD's Wellness Encyclopedia

Bannayan-Zonana Syndrome Bannayan-Zonana Syndrome (BZS) is a rare genetic disorder characterized by multiple congenital anomalies and developmental issues. It is part of a group of disorders known as PTEN hamartoma tumor syndromes (PHTS), which are caused by mutations in the PTEN gene.

Clinical Features[edit | edit source]

Individuals with Bannayan-Zonana Syndrome typically present with a variety of symptoms, which may include:

  • Macrocephaly: An abnormally large head size, often present at birth.
  • Lipomas: Benign fatty tumors that can occur anywhere on the body.
  • Hemangiomas: Benign tumors of blood vessels, often appearing as red or purple skin lesions.
  • Developmental Delay: Delays in reaching developmental milestones, which can vary in severity.
  • Intestinal Polyps: Non-cancerous growths in the gastrointestinal tract, which can cause symptoms such as bleeding or obstruction.

Genetic Basis[edit | edit source]

Bannayan-Zonana Syndrome is caused by mutations in the PTEN gene, which is located on chromosome 10q23.3. The PTEN gene is a tumor suppressor gene, and mutations can lead to uncontrolled cell growth and the development of tumors.

Diagnosis[edit | edit source]

Diagnosis of Bannayan-Zonana Syndrome is based on clinical evaluation, family history, and genetic testing to identify mutations in the PTEN gene.

Management[edit | edit source]

There is no cure for Bannayan-Zonana Syndrome, but management focuses on monitoring and treating symptoms. This may include:

  • Regular screening for tumors and polyps.
  • Surgical removal of lipomas or polyps if they cause symptoms.
  • Developmental support and therapies for children with developmental delays.

Related Conditions[edit | edit source]

Bannayan-Zonana Syndrome is part of the PTEN hamartoma tumor syndromes group, which also includes:

Research and Future Directions[edit | edit source]

Research is ongoing to better understand the role of the PTEN gene in Bannayan-Zonana Syndrome and related conditions. Advances in genetic testing and personalized medicine may improve diagnosis and management in the future.
