Regarding the expression levels of BSND and ATP6V1G3 in carcinomas other than RCC, lung carcinomas were negative (0%) for these protein expressions when examined using immunohistochemical analyses, and the TCGA data showed that the mRNA expression levels of both genes were extremely low in 12 types of carcinoma, including lung carcinoma. The gene discussed is BSND; the disease is lung carcinoma.
