• Note (General): 博士論文全文, 博士論文要旨, 最終試験結果の要旨, 論文審査の要旨; Chronic progressive external ophthalmoplegia (CPEO) is one of the most common mitochondrial disorders. It is characterized by bilateral, slowly progressing loss of extraocular muscle mobility, orbicularis oculi weakness, ptosis and other neuromuscular symptoms, which are caused by the accumulation of multiple mitochondrial DNA (mtDNA) deletions. Many mutations in different nuclear genes, such as POLG1, POLG2, ANT1, and others, have been described as causing autosomal-inherited CPEO with multiple mtDNA deletions. Most causative genes are involved in mtDNA replication impairment. Here, we report a family with CPEO-like symptoms characterized by multiple muscle mtDNA deletions, ptosis, diabetes, hearing loss, mental retardation, and emotional instability. We performed genetic analyses to identify nuclear gene mutations in the family. DNA from the proband was analyzed by whole-exome sequencing. In addition to possible pathogenic mutations, rare variants were prioritized for gene-functional phenotype interpretation. We found possible pathogenetic mutations in the PRIMPOL, BRCA1, CPT2, and GJB2 genes, and functional polymorphisms in the CARD8, and MEFV genes. Multiple functional polymorphism and possible pathogenic mutations may contribute to mitochondrialdisease-like phenotypes in a composite manner.
