MYCN and neoplasm: When calculating the average ratio of mature 3p to 5p expression for each pre-miR we observed a value of 1.02 for the Dicer1 mutant tumor and significantly (z-score 6.71, p-value 9.24x10-12) lower values of 0.97, 0.95 and 0.95 in three control tumors (two MYCN driven, one Lin28b driven, all of them not harboring Dicer1 mutations).
