(BRRS)/Bannayan-Zonana syndrome is a rare [[hamartomatous]] disorder with occurrence of multiple [[subcutaneous]] [[lipoma]]s, [[macrocephaly]] and [[hemangioma]]s.

Bannayan-Riley-Ruvalcaba syndrome (BRRS) is transmitted in [[autosomal dominant]] pattern. Bannayan-Riley-Ruvalcaba syndrome (BRRS) was first discovered by Ruvalcaba, in 1980. It is understood that Bannayan-Riley-Ruvalcaba syndrome (BRRS) is caused by [[Genetics|genetic]] [[mutations]]. The [[Symptom|symptoms]] of BRRS usually develop in the first decade of life. The [[prognosis]] is unknown for Bannayan-Riley-Ruvalcaba syndrome (BRRS). Bannayan-Riley-Ruvalcaba syndrome must be differentiated from [[CLOVES syndrome|CLOVE]] syndromes. The [[incidence]] of Bannayan-Riley-Ruvalcaba syndrome is approximately 1 per 200,000 individuals worldwide. Head [[Magnetic resonance imaging|MRI]] may be helpful in the [[diagnosis]] of Bannayan-Riley-Ruvalcaba syndrome. There is no treatment for Bannayan-Riley-Ruvalcaba syndrome. | ||

Overview
![]() |
(BRRS)/Bannayan-Zonana syndrome is a rare hamartomatous disorder with occurrence of multiple subcutaneous lipomas, macrocephaly and hemangiomas. Bannayan-Riley-Ruvalcaba syndrome (BRRS) is transmitted in autosomal dominant pattern. Bannayan-Riley-Ruvalcaba syndrome (BRRS) was first discovered by Ruvalcaba, in 1980. It is understood that Bannayan-Riley-Ruvalcaba syndrome (BRRS) is caused by genetic mutations. The symptoms of BRRS usually develop in the first decade of life. The prognosis is unknown for Bannayan-Riley-Ruvalcaba syndrome (BRRS). Bannayan-Riley-Ruvalcaba syndrome must be differentiated from CLOVE syndromes. The incidence of Bannayan-Riley-Ruvalcaba syndrome is approximately 1 per 200,000 individuals worldwide. Head MRI may be helpful in the diagnosis of Bannayan-Riley-Ruvalcaba syndrome. There is no treatment for Bannayan-Riley-Ruvalcaba syndrome.
Historical Perspective
- Bannayan-Riley-Ruvalcaba syndrome (BRRS) was first discovered by Ruvalcaba, in 1980.[2]
- Bannayan-Riley-Ruvalcaba syndrome was also mentioned with different names previously by different doctors thinking that they were describing a new condition and the names are as follows:
- Ruvalcaba-Myhre syndrome
- Riley-Smith syndrome
- Bannayan-Zonana syndrome
- The overlap of symptoms between Cowden syndrome and Bannayan-Ruvalcaba-Riley syndrome was made in 1996.[3]
Classification
- There is no established system for the classification of Bannayan-Riley-Ruvalcaba syndrome (BRRS) .
Pathophysiologya
- 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:[4][5][6]
- 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.[7]
- PTEN track backs to 10q23 which encodes and plays a significant role in the following:[8][9]
- 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
Causes
![]() |
Genetic Cause
- Bannayan-Riley-Ruvalcaba syndrome (BRRS) is caused by a mutation in the phosphatase and tensin homolog (PTEN) gene.[11][12][13][14][15][16]
- Different types of mutations occurs in PTEN gene and are as follows:
Differentiating Bannayan-Riley-Ruvalcaba syndrome from Other Diseases
- Bannayan-Riley-Ruvalcaba syndrome must be differentiated from CLOVE syndrome which include the following:[17][18][19][20]
- Congenital lipomatous overgrowth
- Vascular malformations
- Epidermal nevi and
- Cowden syndrome
- Proteus syndrome
- Lhermitte-Duclos syndrome
- Birt-Hogg-Dube syndrome
Epidemiology and Demographics
Incidence
- The incidence of Bannayan-Riley-Ruvalcaba syndrome is approximately 1 per 200,000 individuals worldwide.[21][22]
Prevalence
- The prevalence of PTEN mutations Bannayan-Riley-Ruvalcaba syndrome is approximately 65%.
Age
- Bannayan-Riley-Ruvalcaba syndrome commonly affects individuals of younger age.[23][24]
- The median age for Bannayan-Riley-Ruvalcaba syndrome diagnosis is as young as five years.
Risk Factors
- Apart from mutations in PTEN gene there are no established risk factors for Bannayan-Riley-Ruvalcaba syndrome (BRRS).
Screening
- There is insufficient evidence to recommend routine screening for Bannayan-Riley-Ruvalcaba syndrome (BRRS).
Natural History, Complications, and Prognosis
Natural History
- The symptoms of BRRS usually develop in the first decade of life, and start with symptoms such as developmental delay, macrocephaly and penile lentigines.
Complications
- Common complications of Bannayan-Riley-Ruvalcaba syndrome (BRRS) include:[25][26][27][28][29][30][31]
- Increased risk of following cancers:
- Thyroid cancer: Mostly commonly follicular, very rarely papillary, but never medullary thyroid cancer
- Breast cancer
- Renal cell cancer
- Granulosa cell tumor of the ovary
- Increased risk of following cancers:
Prognosis
- The prognosis is unknown for Bannayan-Riley-Ruvalcaba syndrome (BRRS).
Diagnosis
Diagnostic Criteria
- The diagnostic criteria of Bannayan-Riley-Ruvalcaba syndrome (BRRS) is based on the Cowden syndrome/PHTS criteria, which include:
Pilarski et al diagnostic criteria:
- Pilarski et al diagnostic criteria is proposed by National Comprehensive Cancer Network (NCCN) which include[32]
- Diagnosis require

Laboratory Findings
- PTEN mutation testing by following:
- Sequence analysis of coding region
- Deletion/duplication analysis

- White matter cysts in the parietal lobe, frontal lobe, and temporal lobe
- T2 hyperintensities associated with macrocephaly
Other Diagnostic Studies
- There are no other diagnostic studies associated with Bannayan-Riley-Ruvalcaba syndrome.
Treatment
Medical Therapy
- There is no treatment for Bannayan-Riley-Ruvalcaba syndrome; the mainstay of therapy is treating the symptoms present in the individual like:
Mucocutaneous Manifestations
