Diagram of the study design. Flowchart of the analysis performed on the complete panel of 59 patients, including the Agilent informatic method (on the left) and the visual inspection (on the right), that have led to the detection of 83 CNVs, together with the tables and files generated at each step. In particular, excluding the six already known control CNVs, the remaining 77 are further distinguished based on the DGV database (25 CNVs with a frequency higher than 5%, and thus considered true, and 52 CNVs novel or very rare on DGV) and on a visual classification. Fifteen likely true CNVs and three CNVs located on known HSCR genes have been validated by a different approach, confirming a total of 12 novel “true” CNVs in addition to the 25 already described on DGV. Numbers shown on the top of the diagram (above the red line) refer to samples, while those shown below the red line refer to CNVs (not coincident with the number of samples carrying the CNVs)
