A 52-year-old woman with chronic progressive external ophthalmoplegia (CPEO) with familial hypercholesterolemia (FH) was reported. Her mother died from heart disease, and her elder sister has hypercholesterolemia with swelling of Achilles tendons. She had slowly progressive external ophthalmoplegia, bilateral ptosis, swelling of Achilles tendons since twenties. At 40 years of age, she was pointed out hypercholesterolemia. Physical examination was within normal limits except for bilateral swelling of Achilles tendons. Neurological findings showed bilateral ptosis, disturbance of eye movements, mild proximal muscle weakness and dysesthesia in bilateral hands. Routine laboratory findings were within normal limits except for high serum cholesterol level (512 mg/dl). In the biopsied muscle, there was mild variation in fiber size with several ragged-red fibers and focal cytochrome c oxidase defective fibers. Biochemical analysis of the biopsied muscle revealed normal values in the mitochondrial fraction. Southern blot analysis of the mitochondrial DNA (mtDNA) of the muscle disclosed mixed population of mtDNA, consisting of the normal one and partially deleted (4.9-kilobase). Southern blot analysis of the leukocytes from the patient against the cDNA of LDL receptor was normal at least using the restriction enzyme of BglII, XbaI, EcoRI, PvuII and BamHI. This case has CPEO with deleted mtDNA associated with familial hypercholesterolemia, which is caused to nuclear DNA abnormalities, and is thought to be an important case for us to study the relationship between deleted mtDNA and abnormal nuclear DNA in CPEO.
