In contrast, the 29 patients in the “BCOR rearranged sarcoma” group were younger (p < 0.001) with a median age of 0.9 years overall (0.1–19.1) and specifically 4 years (range, 0.1–19.1) for BCOR::CCNB3 (n = 18) and 1 year (0.3–18.3) for BCOR‐ITD (n = 7). This evidence concerns the gene BCOR and sarcoma.
