PHACTR4 and Mobius syndrome: In the Asian cohort, we identified MB subgroup-specific fusion genes such as a frameshift fusion gene ARID1A-PHACTR4 in WNT-MB (Figures 3A,C), and in-frame fusion genes (e.g., VSNL1-MYCN and NFYC-PPIE) in SHH-MB (Figure 3C), in-frame fusion genes (e.g., ANKRD52-CS and ASAP1-WDYHV1) and frameshift gene fusions such as (e.g., NF1A-GFI1 and NUS1-SLC25A13) in G3-MB (Figure 3C), as well as in-frame fusion genes (e.g., DNMT1-ZGLP1, SAE1-NPAS1, and TET3-GMCL1) and non-coding fusion genes (e.g., DNMT1-AC011511.1) in G4-MBs (Figure 3C and Supplementary Table 4).
