【 摘 要 】

The deletions in the mitochondrial DNA from skeletal muscle samples of two oculopharyngeal muscular dystrophy cases were studied using polymerase chain reaction techniques. The 4977 bp `common deletion' was present in both specimens, exceeding the corresponding values of similarly aged, healthy controls. In the two samples multiple different mitochondrial DNA deletions, some case-specific and present at quite high, although not pathogenetic levels, were observed. The results suggest that mitochondrial DNA deletions, and the `common deletion' in particular, might be a sensitive and early marker of a generalized mitochondrial suffering, due to a variety of pathological and physiological causes.
