The analysis of RNASEH2A copy number alterations and mRNA expression in various types of cancer (prevalence of RNASEH2A CNAs in Table 3, expression summary for CNA types and raw data in Table S12) revealed that the average expression of RNASEH2A is higher in patients with amplifications of the RNASEH2A gene and lower in patients with deep deletions when compared to normal diploid samples. Here, RNASEH2A is linked to cancer.
