The structure of in silico hg38 3q29 locus represented at the top with white background and dark vertical lines. The SD blocks were presented above, 3q29 segments (colored arrows) were overlaid on. Three types of inversions, Type I, Type II, and Type III, detected from this study were presented below the in silico map. Type I represents inversions > 2 mbp in size, Type II represents inversions ~ 289 kbp in size, and Type III represents inverted duplications of five 3q29 segments (black rectangles). Black, orange and blue boxes: 3q29 SD blocks; green arrow: 3q29 segment; black arrow: unique region between SDB and SDC. Strand A at the top, displays reference structures and strand B below represents inverted structures.
