CONTEXT Impaired mitochondrial function may influence processes highly dependent on energy, such as neurodevelopment, and contribute to autism. No studies have evaluated mitochondrial dysfunction and mitochondrial DNA (mtDNA) abnormalities in a well-defined population of children with autism. OBJECTIVE To evaluate mitochondrial defects in children with autism. DESIGN, SETTING, AND PATIENTS ...
Introduction Herein, we describe the interesting case of a 13-year-old female with Kearns-Sayre syndrome (KSS) who underwent a successful T3 ~ L3 posterior spinal instrumentation and fusion (PSIF). KSS is a rare mitochondrial myopathy with only 226 cases reported in published literature as of 1992. It is the result of deletions in mitochondrial DNA and manifests as a triad of: 1) chronic progre...
ANT1 is one of the nuclear genes responsible of autosomal dominant progressive external ophthalmoplegia (adPEO) with mitochondrial DNA multiple deletions. The course of ANT1- related adPEO is relatively benign, symptoms being generally restricted to skeletal muscle. Here we report the case of an Italian 74 years old woman with ANT1-related adPEO and dementia. Further studies are needed to asses...
Mitochondrial DNA (mtDNA) accumulates both base-substitution mutations and deletions with aging in several tissues in mammals. Here, we examine the evidence supporting a causative role for mtDNA mutations in mammalian aging. We describe and compare human diseases and mouse models associated with mitochondrial genome instability. We also discuss potential mechanisms for the generation of these m...
