Detection of "deleted" mitochondrial genomes in cytochrome-c oxidase-deficient muscle fibers of a patient with Kearns-Sayre syndrome.
Using in situ hybridization and immunocytochemistry, we studied a muscle biopsy sample from a patient with Kearns-Sayre syndrome (KSS) who had a deletion of mitochondrial DNA (mtDNA) and partial deficiency of cytochrome-c oxidase (COX; EC 1.9.3.1). We sought a relationship between COX deficiency and abnormalities of mtDNA at the single-fiber level. COX deficiency clearly correlated with a decre...
متن کامل[PCR-based detection of heteroplasmic deleted mitochondrial DNA in Kearns-Sayre syndrome].
OBJECTIVE To describe the clinical data and the results of molecular analyses of the mitochondrial DNA in a patient with Kearns-Sayre Syndrome. METHODS Molecular analyses of mitochondrial DNA from the patient included PCR amplification of a region where the common Kearns- Sayre deletion is located and Genotype-Phenotype correlations are discussed. RESULTS The affected patient showed ptosis,...
متن کاملDetection of platelet mitochondrial DNA deletions in Kearns-Sayre syndrome.
To establish a noninvasive genetic diagnosing method for Kearns-Sayre syndrome, the authors used the polymerase chain reaction (PCR) technique for detecting mitochondrial DNA (mtDNA) deletions in the platelets and directly sequenced the crossover regions of the deleted mtDNA using the fluorescence-based automated sequencing system. The mtDNA deletions were identified in the platelets of three o...
متن کاملAnesthetic management for a patient with Kearns-Sayre syndrome.
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...
متن کاملKearns-Sayre syndrome
The Kearns-Sayre syndrome is a mitochondrial myopathy characterised by ptosis, chronic progressive external ophthalmoplegia, abnormal retinal pigmentation, and cardiac conduction defects. A unique case is reported in which there was rapid development ofprogressive congestive cardiac failure that required cardiac transplantation. A review of published reports of mitochondrial myopathy shows that...
