The first was a congenital SSRMS tumor in the forearm of a 2-week-old girl with a TEAD1::NCOA2 gene fusion (case 7, see figure 3), and the second was an intraosseous SSRMS in the base of the skull of a 12-year-old boy with a FUS::TFCP2 gene fusion (case 8). This evidence concerns the gene FUS and neoplasm.
