Examples for five classifications of inversions verified using PacBio and Minion reads: Simple Inversion (A), inv-dup (B), inv-del (C), MultiDel with Inv (here abbreviated as inv-2dels) (D) and complex (E). (F) Several further examples of inverted duplications (inv-dup), the most common form of inversion-associated SV identified in the phase 3 release set. The figure is depicting DNA sequence alignment dotplots (same arrangement as in Figure 3), with the Y-axis referring to PacBio DNA single molecule sequencing reads and the X-axis referring to the reference genome assembly (hg19). Inverted sequences are highlighted in red. Sequence analysis suggests that these inverted duplications are not typically associated with retrotransposition.
