Birt-Hogg-Dubé syndrome

Overview

Birt-Hogg-Dubé syndrome is a rare genetic disorder. It causes multiple noncancerous tumors to develop in the skin, lungs, and kidneys. These tumors are called fibrofolliculomas, and they usually appear on the face, neck, and upper body. People with this syndrome may also have an increased risk of developing kidney cancer, a type of lung cyst called pneumothorax, and an abnormal growth in the lungs known as a pulmonary cyst.

The syndrome is caused by mutations in the FLCN gene. This gene normally helps control cell growth and division, so when it is mutated, tumors can form. Birt-Hogg-Dubé syndrome is typically inherited in an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the mutated gene to develop the condition. Diagnosis of this syndrome is usually made based on a person's symptoms, family history, and genetic testing. Management of Birt-Hogg-Dubé syndrome may involve regular monitoring for tumor growth and screening for kidney cancer.
