OBSCN and nonpapillary renal cell carcinoma: We discovered that OBSCN mutations were correlated with OS (p = 0.0096) and DFS (p = 0.0048) in the TCGA-KIRC cohort, and with DFS (p = 3.28e-6) in the RECA-EU cohort, although there was no correlation of OBSCN mutations with survival in our 22 Korean ccRCC patients.
