The authors sequenced POLG1, C10ORF2, and ANT1 in 38 sporadic progressive external ophthalmoplegia patients with multiple mitochondrial DNA (mtDNA) deletions. Causative mutations were identified in approximately 10%of...
Objective: To document novel homozygous mutations in the gene for deoxyguanosi ne kinase (DGK) in 3 children with mitochondrial DNA depletion. Design: Clinical features included liver failure, hypotonia, and nystagmus...
Background: Large-scale mitochondrial DNA (mtDNA)-deletions are associated w ith clinical conditions such as Kearns-Sayre syndrome and chronic progressive e xternal ophthalmoplegia in adults and Pearson syndrome in ch...
