[Pneumothorax as an early indication for a genetic disorder]

Several hereditary disorders, with highly variable and sometimes difficult to recognize manifestations, can present with a spontaneous pneumothorax. Options to perform DNA-testing have changed rapidly, as a result of which physicians of diverse disciplines are coming into contact with hereditary disorders.

Two patients with a history of multiple spontaneous pneumothoraxes were seen at the outpatient clinic of the department of Clinical Genetics. Based on family history and physical examination, a suspicion of an underlying hereditary disorder arose. Birt-Hogg-Dubé syndrome and vascular Ehlers-Danlos syndrome were diagnosed through DNA-testing. Based on this, additional screening advices were given and DNA-testing became possible in the family.

A spontaneous pneumothorax may be a manifestation of an underlying hereditary disorder. With attention to clinical symptoms and family history, physicians can contribute to timely diagnosis. In many cases this results in significant health benefits for both the patient and affected family members, such as screening for kidney cancer in the case of Birt-Hogg-Dubé syndrome.
