For example, the testis-specific BRD gene BRDT was not solely detected in testicular germ cell tumors (TGCT); it was also found in a small fraction of lung cancers (25.34% of lung adenocarcinomas [LUAD] and 16.97% of lung squamous cell carcinoma [LUSC]), uterine carcinosarcoma (UCS;16.07%), and esophageal carcinoma (ESCA; 11.18%). The gene discussed is BRDT; the disease is squamous cell lung carcinoma.
