Importantly, we noted also other genetic changes in tumor suppressors co‐occurring with STAT3/5 gains, namely STAT1 copy number losses in 41% (n = 7/17; range −0.122 to −0.309 log2 ratios) and SOCS1 losses in 18% of samples (n = 3/17; range −0.117 to −0.210; Fig 1B and C, and Dataset EV2. The gene discussed is STAT1; the disease is neoplasm.
