Friedreich Ataxia

Pediatric Neurology
With the introduction of potential new therapy for Friedreich ataxia, the disorder has taken on a new importance in the world of pediatric neurology. Originally described more than 150 years ago, large scale clinical studies have defined diagnostic criteria and the underlying mutation as a biallelic, unstable expansion of an intronic guanine adenine ...

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Juvenile Huntington Disease With Cerebellar‐Predominant Atrophy Identified by Genome Sequencing

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Juvenile Huntington disease accounts for a small fraction of Huntington disease cases and is driven by the largest trinucleotide repeat expansions. We describe a 6‐year‐old boy with progressive global regression, generalized dystonia, and epilepsy, in whom serial imaging showed striking cerebellar‐predominant atrophy with an initially normal ...

Establishing Sensory Neurons as Therapeutic Targets in Peripheral Neuropathy Driven by Polyglutamine Expanded Murine ATXN3

Annals of Neurology, EarlyView.
Repeat expansion disorders frequently involve peripheral neuropathy, yet mechanisms remain unclear. Using a spinocerebellar ataxia type 3 (SCA3) Knock‐In Atxn3Q300/Q6, we identify progressive sensorimotor deficits, peripheral nerve pathology, and dorsal root ganglia RNA splicing dysregulation.

Mitochondrial Iron-Sulfur Cluster Dysfunction In Neurodegenerative Disease

Frontiers in Pharmacology, 2014
Growing evidence supports a role for mitochondrial iron metabolism in the pathophysiology of neurodegenerative disorders such as Friedreich ataxia and Parkinson disease as well as in the motor and cognitive decline associated with the aging process. Iron-

Evaluating discrepancies between high‐yield neuroscience conditions in preclerkship medical education and national clinical incidence

Anatomical Sciences Education, EarlyView.
Abstract Medical education must balance foundational science with clinical relevance. Increasing emphasis on standardized assessments has led to prioritization of “high‐yield” conditions—those most likely to be assessed. Subsequently, educators and students often prioritize these conditions.

Diagnosing Friedreich's ataxia [PDF]

Archives of Disease in Childhood, 1998
Clinical diagnosis is still of the utmost importance and following our review of cases diagnosed using the strict criteria, 100% were homozygous for the expansion. However, now that there is a relatively simple direct genetic test, the diagnosis can be considered in more unusual cases.

Genetic developmental and epileptic encephalopathies in adulthood: Gaps in evidence and care

Epilepsia Open, EarlyView.
Abstract Developmental and epileptic encephalopathies (DEEs) are a heterogeneous group of the most severe epilepsies, characterized by seizure onset and neurodevelopmental delay in infancy or childhood, often with additional neurological and systemic comorbidities.

Drug Repositioning in Friedreich Ataxia

Frontiers in Neuroscience, 2022
Friedreich ataxia is a rare neurodegenerative disorder caused by insufficient levels of the essential mitochondrial protein frataxin. It is a severely debilitating disease that significantly impacts the quality of life of affected patients and reduces ...
