Exon Array data of fusion partner genes. Exon expression profiles of fusion partner genes EWSR1 (A) and ATF1 (B) are shown by line graphs with target areas of probe sets and genomic DNA structures. SarcomaA cell line and reference samples (breast cancer cell lines) are indicated by red and pink lines, respectively. Known breakpoints are shown by blue lines. Characters at top and bottom of probe set numbers indicate annotations: C = core, e = extended, f = full, U = unique, S = similar, M = mixed.
