Although only PRKDC (DNAPKcs) and XRCC6 (Ku70) showed high expressional correlation with PRMT5 among the matched tumor tissues (N = 43), high positive correlations of the PRMT5 levels were detected with BRCA1, PRKDC, RAD51, and XRCC6 when all the available tumor data were included (N = 522) (column 4, Table 1). Here, XRCC6 is linked to neoplasm.
