Abstract
Birt-Hogg-Dubé syndrome (BHDS, MIM 135150) is an autosomal dominant condition characterized by presence of skin fibrofolliculomas, lung cysts, spontaneous pneumothorax and renal cancer. The disease is caused by germ-line mutations of the FLCN gene, which encodes protein folliculin.
BHDS is a rare condition with high penetrance and variable expression. Clinical recommendations include increased care during general anesthesia due to a higher risk of pneumothorax, and long-term follow-up due to an elevated risk of renal cancer.
Diagnostic and predictive DNA tests are available; prenatal and preimplantation diagnosis is possible
