Novel Missense Mitochondrial ND4L Gene Mutations in Friedreich's Ataxia
Objective(s) The mitochondrial defects in Friedreich's ataxia have been reported in many researches. Mitochondrial DNA is one of the candidates for defects in mitochondrion, and complex I is the first and one of the largest catalytic complexes of oxidative phosphorylation (OXPHOS) system. Materials and Methods We searched the mitochondrial ND4L gene for mutations by TTGE and sequencing on 30...
متن کاملStructural and functional MRI abnormalities of cerebellar cortex and nuclei in SCA3, SCA6 and Friedreich's ataxia.
Spinocerebellar ataxia type 3, spinocerebellar ataxia type 6 and Friedreich's ataxia are common hereditary ataxias. Different patterns of atrophy of the cerebellar cortex are well known. Data on cerebellar nuclei are sparse. Whereas cerebellar nuclei have long been thought to be preserved in spinocerebellar ataxia type 6, histology shows marked atrophy of the nuclei in Friedreich's ataxia and s...
متن کاملFriedreich's ataxia. Revision of the phenotype according to molecular genetics.
Friedreich's ataxia is an autosomal recessively inherited neurodegenerative disorder caused by expansions of an unstable GAA trinucleotide repeat in the STM7/X25 gene on chromosome 9q. We studied the (GAA)n polymorphism in 178 healthy controls and 102 patients with idiopathic ataxia. The repeat size ranged from 7 to 29 (GAA)n motifs on normal chromosomes and from 66 to 1360 trinucleotide repeti...
متن کاملFriedreich's ataxia cardiomyopathy: case based discussion and management issues.
Cardiac involvement is common in Friedreich's Ataxia and is a common cause of premature death. Evidence regarding treatment of congestive heart failure in patients with Friedreich's Ataxia is lacking. The case of a 31-year-old male with advanced Friedreich's Ataxia who presented with an acute diarrhoeal illness and features of acute heart failure is discussed. We then review the reported cardia...
متن کاملFriedreich’s Ataxia: A Neuronal Point of View on the Oxidative Stress Hypothesis
A prominent feature of Friedreich's ataxia (FRDA) is the neurodegeneration of the central and peripheral nervous systems, but little information is available about the mechanisms leading to neuronal damage in this pathology. Currently, no treatments delay, prevent, or reverse the inexorable decline that occurs in this condition. Evidence of oxidative damage has been demonstrated in Friedreich's...
