The VL subgroup (n = 8; including four YWHAE-NUTM2 fusion, three BCOR-ITD and the GREB1-NCOA2 positive tumors) was characterized by a very low immune infiltrate for all cell types, while the L subgroup (n = 14; including most PHF1-fused tumors) harbored higher densities of macrophages, and the I subgroup I (n = 16; including 3 UUS and the two GLI1-rearranged neoplasm) was characterized by higher densities of CD4+ T cells and macrophages. This evidence concerns the gene GLI1 and neoplasm.
