ERCC5 and neoplasm: Kidney renal clear cell carcinoma (KIRC) was noticeably different from the other tumors in that no genes on chromosome 13 correlated strongly with ERCC5. Interestingly, KIRC is an outlier as a tumor type where ERCC5 was highly overexpressed compared to normal cells (Figure 2A), possibly reflecting more DNA damages caused by toxin exposure in kidney.
