(a) Right side of chromosomal ideograms: red line indicates deletion; blue=insertion; yellow=inversion breakpoint; the double length indicates SV observed in both individuals. Left side of ideogram: the line lengths indicate size of event in log-scale (events ≥1 Mb are drawn at same length, corresponding to the line indicated to the right (‘Scale’); unmated insertions are indicated at a length corresponding to 1 kb); line colors indicate predominant repetitive sequences in ±3 kb window of the predicted breakpoint junction (according to numbers/ occurrences of elements annotated in http://humanparalogy.gs.washington.edu  (SDs) and www.repeatmasker.org): red=SDs; blue=LINEs; yellow=LTRs; green=Microsatellites; black=two or more repetitive elements with equal frequency; gray: no repeat association.
