Figure 1From: OPA1-related dominant optic atrophy is not strongly influenced by mitochondrial DNA background Phylogenical repartition of the 41 OPA1 mutation carriers. The phylogenic tree was based on recent total sequencing studies of mitochondrial DNA [11, 12]; the new haplogroup nomenclature is used[17]. The different polymorphisms used for haplogroup determination in this study are indicated in blue. The Red Cross indicate the number of individuals per haplogroup.Back to article page
