Fig. 1From: Genome-wide copy number variant analysis for congenital ventricular septal defects in Chinese Han populationWorkflow of CNV analysis and candidate genes discovery. CNV calls by DNA Analytics were performed by using the ADM2 algorithm, with a sensitivity threshold of 6.0 and a minimum of 5 probes. The QC metrics table was used to check signal intensity and background noise. Above 0.22 of DLR Score (Derivative Log Ratio) was set as the cutoff to avoid false CNVs. 6 cases were removed because of bad quality of data during the QC filter.6 cases with aneuploid abnormals (Trisomy X and Down syndrome) were not put into further analysisBack to article page
