Intriguingly, two genes targeted by miR-196b-5p and miR-200b-3p were found downregulated in adult MBs in the two datasets with the higher number of cases (GSE49243 and GSE21140): (i) IGF2BP3 (insulin-like growth factor-2 mRNA-binding protein 3) and (ii) Myb (c-myb proto-oncogene). The gene discussed is IGF2BP3; the disease is Mobius syndrome.
