Inheritance autosomal dominant; existence of sporadic cases

Clinics

Note Bannayan-Riley-Ruvalcaba syndrome is an overgrowth syndrome / hamartomatous polyposis condition with an increased risk of benign and malignant tumours; other overgrowth syndromes at (known) risk of tumourigenesis are :
  • Beckwith-Weideman syndrome,
  • Sotos syndrome (cerebral gigantism),
  • Hemihyperplasia (hemihypertrophy), and
  • Simpson Golabi Behemel syndrome.
  • Phenotype and clinics onset in chilhood (in contrast with Cowden disease, although an allelic disorder, see below); more often found in male patients (lower penetrance in female patients).
    - overgrowth at birth (postnatal growth decelerates).
    - macrocephaly
    - hypotonia and mental deficiency
    - subcutaneous and visceral lipomas and hemangiomas, and intestinal juvenile polyposis.
    - myopathy of the proximal type in 2/3 of cases
    - pigmentation spots of the male genitalia
    Neoplastic risk
  • multiple lipomas (75% of cases).
  • hemangiomas (40%).
  • hamartomatous polyps (ileus and colon; 45%).
  • lymphangiomas (10%).
  • Genes involved and Proteins

     
    Gene NamePTEN
    Location 10q23
    Protein
    Description 403 amino acids
    Function protein tyrosine phosphatase; tumour suppressor gene
    Mutations
    Germinal may be not all Bannayan-Riley-Ruvalcaba syndrome cases are due to PTEN mutations; germ-line mutations have also been described in Cowden disease and in some cases with juvenile polyposis syndrome.
    Somatic PTEN is mutated in a large number of cancer types
