Given that GRAMD1C expression correlates with overall survival in ccRCC46 and forms a heteromeric complex with the other GRAMs22, we investigated the involvement of the complete GRAM family in ccRCC using tumor gene expression data from the TCGA Kidney Renal Clear Cell Carcinoma (KIRC) cohort49. Here, GRAMD1C is linked to nonpapillary renal cell carcinoma.
