Two-dimensional scatterplot showing the location of the selected deletion (red diamond) versus the full dataset (grey dots). Each point represents an mtDNA rearrangement with the 5’ breakpoint on the x-axis and the 3’ breakpoint on the y-axis.

Circular mtDNA plot specifying the location of the deleted region (black bar).
Length distribution of the deleted region in the selected deletion (red bar) versus the full dataset (grey bars) .The cases were grouped 100-nt windows.
