CNV breakpoints composition analysis. A: Base composition of CNV breakpoints. GC-content in 400 bp windows around the breakpoint recorded at the center of each window. Negative locations represent windows inside the CNVs and colors represent the proportion of CNVs with a size that can cover a window at a specific distance inside the CNVs. B: Enrichment of L1 repeats in CNV breakpoints. Observed to expected ratios of 5 classes of differentially diverged L1 repeats in CNV breakpoints. Colors represent the size of the CNV breakpoint.
