Figure 1

Phylogenetic network of mtDNA. The network was constructed on the basis of variation in the D-loop sequence of 103 Finnish children with HI. Fast-evolving sites, m.303, m.311 and m.16519 were not included in the network. The frequencies (%) of mtDNA haplogroups are shown. Numbers inside the nodes denote samples. The polymorphic variants shown on the lines connecting the nodes are transitions unless marked otherwise. ins = insertion, del = deletion, @ = back mutation. The outgroup is mtDNA from an African individual [GenBank:AF346980].
