Genes

FLCN

Conditions

  • Birt-Hogg-Dube Syndrome

Clinical Utility

  • An individual with a personal and family history of tumors or other clinical features associated with Birt-Hogg-Dubé syndrome (BHD), such as oncocytic, chromophobe, or oncocytic hybrid renal tumors; benign skin papules (fibrofolliculomas, trichodiscomas/angiofibromas, perifollicular fibromas, acrocordons); multiple bilateral lung cysts; spontaneous pneumothorax
  • An individual with multiple skin papules with at least one biopsy-proven fibrofolliculoma
  • An individual with bilateral or multi-focal oncocytic, chromophobe, or oncocytic hybrid renal tumors
  • An individual with a personal and family history of unexplained isolated primary spontaneous pneumothorax (PSP)
  • An unaffected individual with a family history suggestive of BHD (see above) when an affected individual is unavailable for his or her own genetic testing
