EGR1 and neoplasm: All had at least some SCNAs. No clear differences between NF1 and non-NF1. Most had amplifications, and had more gains than losses. Average 17 SCNAs/tumor. No losses common to more than two tumors except 16q12-22 in three. Gains: 4q26 and 6q (7 each), 4q12-q26, 11q14, 15q21, 21q21 (6 each), and 5p14, 5q21, 11q14-q22, 12q21, 14q21 (5 each). One had loss of chromosome 22. Specific gains found at genes EGFR, MSH2, CDK6, DDX15; specific losses were at genes CDH1, EGR1, CTSB, GATA3.
