Table 1. Five fusion genes in common between breast tumors and breast cancer cell lines.

5´fusion gene partner	3´fusion gene partner	No of fusions (%)	Cell lines
CCDC6	ANK3	2 (0.12)	UACC893
ESR1	CCDC170	11 (0.64)	ZR751
GATAD2B	NUP210L	1 (0.06)	MCF-7

Fusion genes were analyzed in a total of 1724 breast tumors. The number of breast tumors carrying the fusion genes that were found in common between breast tumors and breast cell lines is shown in this table. The common fusions were analyzed in other tumor types through this website: www.tumorfusions.org [4]. GATAD2B-NU210L appeared once in these tumor types: uterine carcinosarcoma (UCS), lung adenocarcinoma (LUAD) and ovarian tumors (OV). ITGB6-RBMS1 was found in two tumors from bladder cancer (BLCA).
