Different patterns between gene fusions and read-throughs. (A) Exons involved in gene fusions and read-throughs follow different patterns. A gene fusion (or read-through) transcript can be categorized into six classes involving the first, second to last, or any other exon of the 5′ gene with either the second or downstream exon of the 3′ gene. (B) Recurrence of gene fusions and read-throughs across 62 breast cancer patients. The horizontal axis is number of patients, and the vertical axis is fraction of events. Blue bars represent gene fusions and red bars represent read-throughs. The pie chart shows the percentage of singleton gene fusions (left) and read-throughs (right).
