Quantitative analysis of mitochondrial DNA deletion in paraffin embedded muscle tissues from patients with KSS and CPEO

Abstract

AbstractThe percentage of common deletion of mitochondrial DNA (mtDNA) was determined quantitatively by a PCR-based, non-radioactive method in DNA extracted from formalin-fixed, paraffin-embedded skeletal muscle tissues from two patients with Kearns Sayre syndrome (KSS) and one with chronic progressive external ophthalmoplegia (CPEO). The method involved PCR cycle titration of wild-type and deleted mtDNA in parallel, staining of gel bands with the sensitive fluorescence dye SYBR Green I, and quantitation of intensity on a computer screen by the NIH image program. We determined 75% and 71% common deletion of mtDNA in the KSS patients and 35% in the CPEO patient
