MYC and breast carcinoma: Table S3 shows the regions with frequent low and/or high level CNAs in the 49 IBCs, defined using the GISTIC algorithm with a significance threshold of p<0.05. Sixty-five regions were gained/amplified. The top ten regions (in term of median GISTIC score) resided on 17q, 6p, 1q, 8q, 11q, 19q, and 8p chromosomal arms. Many of these regions contain genes involved in breast cancer, such as ERBB2, MYC, CCND1 and FGFR1. Thirty-four regions were gained in at least 15% of IBCs.
