Bannayan-Riley-Ruvalcaba syndrome
Overview
Bannayan-Riley-Ruvalcaba syndrome is a rare genetic disorder that affects various parts of the body. It is caused by changes in a gene called PTEN, which plays a role in controlling cell growth and division. People with this syndrome may have an increased risk of developing certain types of cancers, such as breast, thyroid, and colorectal cancer.
Individuals with Bannayan-Riley-Ruvalcaba syndrome may also have non-cancerous growths called hamartomas that can develop in various organs, including the skin, intestine, and brain. Other common features of this syndrome include intellectual disability, macrocephaly (larger than average head size), and skin abnormalities. Treatment for Bannayan-Riley-Ruvalcaba syndrome typically involves managing the symptoms and screening for cancer regularly to detect it early.

Symptoms of Bannayan-Riley-Ruvalcaba syndrome
Bannayan-Riley-Ruvalcaba syndrome can cause a variety of symptoms that affect a person's health. People with this syndrome may have intellectual disabilities, learning difficulties, or developmental delays. Additionally, individuals with this condition often have large head sizes, which is known as macrocephaly. They may also have tumors called hamartomas that can develop on different parts of the body, such as the skin, intestines, or brain. Other common signs of Bannayan-Riley-Ruvalcaba syndrome include muscle weakness, joint problems, and skin changes like dark spots or freckles.
Furthermore, individuals with this syndrome may experience gastrointestinal issues such as constipation or diarrhea, as well as problems with their heart, eyes, and thyroid gland. Some people may also have an increased risk of developing certain types of cancer, so regular medical check-ups are important. Overall, Bannayan-Riley-Ruvalcaba syndrome is a complex condition that requires close monitoring and management by healthcare professionals.
How common is Bannayan-Riley-Ruvalcaba syndrome
Bannayan-Riley-Ruvalcaba syndrome is a rare genetic condition. It is estimated to affect fewer than 1 in 200,000 people worldwide. This syndrome is caused by mutations in a gene called PTEN, which plays a role in regulating cell growth and division. People with Bannayan-Riley-Ruvalcaba syndrome may develop various symptoms, including macrocephaly (an abnormally large head size), intellectual disabilities, benign tumors called hamartomas, and skin abnormalities. While this syndrome is not very common, it is important for healthcare providers to be aware of its signs and symptoms to provide appropriate care and support to affected individuals.
Causes of Bannayan-Riley-Ruvalcaba syndrome
Bannayan-Riley-Ruvalcaba syndrome is caused by changes in a person's genes. These changes can be inherited from a parent or can happen spontaneously. The syndrome is linked to mutations in a gene called PTEN, which plays a role in controlling cell growth and division. When there are changes in this gene, it can lead to the development of Bannayan-Riley-Ruvalcaba syndrome.
Additionally, the syndrome can also be caused by de novo mutations, which means that the mutation occurred for the first time in the affected person and was not inherited from a parent. This can make it difficult to predict who might develop the syndrome. Overall, the causes of Bannayan-Riley-Ruvalcaba syndrome are related to alterations in the PTEN gene and can be either inherited or occur spontaneously.
Who is affected by it
Bannayan-Riley-Ruvalcaba syndrome is a rare genetic disorder that affects both males and females. People with this syndrome may experience a variety of symptoms such as intellectual disability, developmental delay, macrocephaly (abnormally large head size), lipomas (fatty lumps), and pigmented spots on the skin. Additionally, individuals with this syndrome may have an increased risk of certain types of cancer, thyroid problems, and other medical issues. The syndrome is caused by mutations in the PTEN gene and can affect people of all ethnicities.
Types of Bannayan-Riley-Ruvalcaba syndrome
There are three types of Bannayan-Riley-Ruvalcaba syndrome: BRRS type 1, BRRS type 2, and BRRS type 3. BRRS type 1 is the most common type and is characterized by multiple noncancerous tumors, intellectual disability, and macrocephaly (larger head size). BRRS type 2 is similar to type 1, but with an increased risk of certain cancers, especially breast and thyroid cancer. BRRS type 3 is the rarest type and is associated with a specific mutation in the gene that causes the syndrome. It is characterized by an increased risk of developing early-onset breast cancer.
Diagnostic of Bannayan-Riley-Ruvalcaba syndrome
Doctors can diagnose Bannayan-Riley-Ruvalcaba syndrome by looking at a person's symptoms and doing certain tests. They might see signs like macrocephaly (having a large head) or skin changes. Doctors can also do genetic testing to look for changes in specific genes linked to the syndrome. Imaging tests like MRIs can show abnormalities in the brain or other parts of the body. By putting all this information together, doctors can make a diagnosis of Bannayan-Riley-Ruvalcaba syndrome.
Treatment of Bannayan-Riley-Ruvalcaba syndrome
Treatment for Bannayan-Riley-Ruvalcaba syndrome is focused on managing the symptoms and complications that may arise.

Additionally, studies investigate the various physical and developmental symptoms of BRRS, such as macrocephaly (enlarged head), benign tumors, and intellectual disabilities, in order to improve patient outcomes and quality of life. Through ongoing research efforts, scientists continue to deepen their understanding of BRRS and work towards more effective therapies and interventions for individuals with this syndrome.
History of Bannayan-Riley-Ruvalcaba syndrome
The history of Bannayan-Riley-Ruvalcaba syndrome can be traced back to the late 1970s. It is a rare genetic disorder that was first described by Dr. Hamish Bannayan, Dr. Penny Riley, and Dr. Sergio Ruvalcaba. The syndrome is characterized by multiple noncancerous tumors called hamartomas that can develop in various parts of the body, including the intestines, skin, and brain. These doctors identified a pattern of features in patients that distinguished this syndrome from other similar conditions.
Over the years, advancements in genetic testing and research have helped to better understand the underlying genetic mutations that cause Bannayan-Riley-Ruvalcaba syndrome. It is now known to be caused by mutations in the PTEN gene, which plays a role in regulating cell growth and division. Individuals with this syndrome may experience a range of symptoms, including developmental delays, intellectual disabilities, and an increased risk of certain cancers. Despite its rarity, ongoing studies continue to uncover more information about this complex syndrome.
