Loss‐of‐function pathogenic variants of FLCN are known to cause Birt‐Hogg‐Dubé (BHD) syndrome, an autosomal dominant disorder characterized by pulmonary and renal cysts, spontaneous pneumothorax, benign cutaneous fibrofolliculomas, and an increased risk of developing kidney tumors (Schmidt & Linehan, 2015). The gene discussed is FLCN; the disease is kidney neoplasm.
