Figure 4. Mitochondrial haplogroup analysis between childhood cataract families. The map generated for the mitochondrial alterations for each family was analyzed for haplogroups. Family mt1A showed M4 haplogroup and family mt2A, mt3A fall in to M39 haplogroups. The phylogenetic networks and evolutionary branching was constructed using Network 4.5.1.0. The reduced median or RM network algorithm was used providing binary data of the mitochondrial genomic variations. M-Macrohaplogroup, M4’30- Superhaplogroup, M4 haplogroup for family mt1A and M39 haplogroup for families mt2A, mt3A.
