Overview
Bannayan-Riley-Ruvalcaba syndrome (BRRS) is transmitted in autosomal dominant pattern. It is understood that Bannayan-Riley-Ruvalcaba syndrome (BRRS) is the result caused gene mutations. PTEN track backs to 10q23 which encodes and plays a significant role
Pathophysiology
Genetics
Pathogenesis
- Bannayan-Riley-Ruvalcaba syndrome (BRRS) is transmitted in autosomal dominant pattern, but sporadic cases have been reported.
- The disease belongs to a family of hamartomatous polyposis syndromes, which also includes Peutz-Jeghers syndrome, juvenile polyposis and Cowden syndrome.
- It is understood that Bannayan-Riley-Ruvalcaba syndrome (BRRS) is the result caused by the following gene mutations:[1][2][3]
- Germline phosphatase and
- Tensin homolog (PTEN) mutations.
- Patients who have Bannayan-Riley-Ruvalcaba syndrome (BRRS), have a positive association with PTEN mutations in 55 to 60 % of cases.[4]
- PTEN track backs to 10q23 which encodes and plays a significant role in the following:[5][6]
- Phosphatidylinositol 3,4,5-triphosphate, a phospholipid in the phosphatidylinositol 3-kinase pathway/Akt pathway
- Effects G1 cell cycle arrest and apoptosis
- Cellular proliferation and
- Migration
