Importantly, 9 of these snoRNAs were also identified by our analysis with a different methodological approach, namely SNORA21, SNORA56, SNORD12B, SNORD12C, SNORD41, SNORD15A, SNORD15B, SNORD72, SNORD102, confirming the observation that these snoRNAs play an important role in cancer development. This evidence concerns the gene SNORD12C and cancer.
