What is BHD? 

Birt-Hogg-Dubé syndrome, also known as BHD, is a rare genetic condition caused by mutations in a gene called folliculin. 600 families worldwide are known to have BHD but it is likely underdiagnosed.

People with BHD can develop benign skin bumps, lung cysts, collapsed lungs and kidney cancers. Importantly if the symptoms are well managed, most people with BHD live normal lives.
