Dear all,

please could you help with the interpretation of the following finding: I have being using several SV callers (including MANTA) to call structural variants in the cancer genomes. In one case, the prediction is of a deletion overlapping almost completed an area that is duplicated (please see below the coordinates), and the question is : in the absence of SNV information, is it possible to call deletion on a chromosome and duplication on the other chromosome ? Or possibly, is there any other interpretation ? thank you ;) !
