Representative sequencing chromatograms revealing mtDNA mutations in tRNA^leu1 gene (AML No.112 patient) and CYTB gene (AML No.50 patient) as nonsynonymous mutations. (A) mtDNA tRNA^leu1 gene mutation-affected amino acid change (Ala→Thr) for AML patient No.112. (B) mtDNA CYTB gene mutation-affected amino acid change (Ala→Thr) for AML patient No.50.
