CPEOの歴史は1868年のvon Graefeによる最初の記載に始まる。1958年にKearnsとSayreがCPEO・網膜色素変性・心伝導障害の三徴候を記述した。1972年に筋生検でragged red fiber(ボロボロの赤色線維)が発見され、1988〜1989年にmtDNA欠失が検出された。2000年には多発mtDNA欠失を伴う初の核DNA(nDNA)変異が同定された1)。

Katayama Uedaら(2025)は日本人男性CPEO症例においてtRNAGlu遺伝子の新規変異(m.14677T>C)を同定した。ragged red fiberにおける変異割合の中央値は88.1%であり、非ragged red fiber(中央値17.1%)と比較して有意に高値であった(P = 0.03)3)。
