Overview

Bannayan-Riley-Ruvalcaba syndrome (BRRS) is caused by a mutation in the phosphatase and tensin homolog (PTEN) gene.

Genetic Cause

Bannayan-Riley-Ruvalcaba syndrome (BRRS) is caused by a mutation in the phosphatase and tensin homolog (PTEN) gene.^[1]^[2]^[3]^[4]
Different types of mutations occurs in PTEN gene and are as follows:
- Germline intragenic mutations in PTEN gene
- Gross gene deletions in PTEN gene
- Mutations in the PTEN gene promoter region results in heterozygous germline mutations
- Deletion in exons 1-5 of PTEN gene
