Table 1.

Summary table of the sequenced samples. (Allele frequencies for the 14 sites sequenced in the blood, cheek and hair samples of 11 individuals. The MAF of the hair sample listed in the table is an average of the MAF of all shafts collected from the donor. The designation of minor versus major allele is based on the minor allele found in the blood and cheek tissue. For those sites located in the coding region of the mtDNA, the base change from the minor allele and resulting amino acid were recorded to determine if it was a synonymous or non-synonymous heteroplasmy.)
