Further analyses indicated that MYCN mRNA levels neither correlated positively with EIF4EBP1 mRNA levels across all MB groups ([r] 0.220, p value < 0.0001; Supplementary Fig. 2A; [r] 0.087, p value = n.s.; Supplementary Fig. 2B) nor in Group 3 MBs ([r] −0.199, p value < 0.05; Supplementary Fig. 2C; [r] −0.468, p value < 0.001; Supplementary Fig. 2D). This evidence concerns the gene MYCN and Mobius syndrome.
