The tool PolyPhen-2 (http://genetics.bwh.harvard.edu/pph2/) was used for predicting the damaging effect of a missense mutation. The conservation index (CI) was computed by using MitoTool (http://www.mitotool.org/). The presence of the mutation as a haplogroup-specific variant was scored relative to the available global mtDNA phylogenetic tree by using Phylotree (http://phylotree.org/tree/main.htm). Co: controls.
