Finding structural variant .vcf files for cancer cell lines

Question

[nicolas.ares]

Hi I'm working on fusion detection software, and I would like to add the option for the users to give a .vcf file containing the structural variants for the cell line of study so as to perform a prioritization of the calls. For creating this feature I need to find a vcf that contains variants for one of the following cell lines: BT-474, KPL-4, MCF-7, and SKBR3 which are my testing dataset.

Is there any database that contains structural variants from commonly used cell lines?

Thanks in advance.
