Development of a new screening method to determine the main 52 mitochondrial haplogroups through a single minisequencing reaction.

This work presents the design, development and optimization of a screening method based on single-base extension sequencing to simultaneously analyze a panel of 52 mitochondrial SNPs. This enables to recognize the main mitochondrial haplogroups and to discriminate even between lineages from the same phylogenetic branch that diverged in different continents. The unavailability of individuals harboring infrequent variants was a limitation to optimize the panel.
