Role of Mitochondria in Ataxia-Telangiectasia: Investigation of Mitochondrial Deletions and Haplogroups

Ataxia-Telangiectasia (AT) is a rare human neurodegenerative autosomal recessive multisystem disease that is characterized by a wide range of features including, progressive cerebellar ataxia with onset during infancy, occulocutaneous telangiectasia, susceptibility to neoplasia, occulomotor disturbances, chromosomal instability and growth and developmental abnormalities. Mitochondrial DNA (mtDN...

[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,...

شناسایی یک حذف بزرگ در DNA میتوکندریایی بیماران ایرانی مبتلا به آریتمی قلبی

Introduction: Long QT Syndrome is one of the arrhythmic disorders of the heart that causes sudden cardiac death in patients. Most of the investigations have focused on nuclear genome for finding genetic defects in these disorders, but some of the cases with LQTS cannot be explained by mutations of identified genes. It prompted the authors to focus on the mitochondrial DNA and monitor rearrangem...

Hypoparathyroidism as the First Mani-Festation of Kearns-Sayre Syndrome: A Case Report

Kearns-Sayre syndrome is a mitochondrial myopathy, which was first described by Tomas Kearn in 1958. Diagnostic symptoms of this condition include retinitis pigmentosa, chronic progressive external ophthalmoplegia, and one or more of the following factors: cardiac conduction system diseases, cerebellar ataxia, and cerebrospinal fluid (CSF) with protein content above 100 mg/dL. The nature of thi...
