Patient and Family Reported Clinical Picture of IRF2BPL‐Related Disorders

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT IRF2BPL‐related disorder is a neurodevelopmental disorder caused by heterozygous variants in the IRF2BPL (Interferon Regulatory Factor 2 Binding Protein‐Like) gene. The few reports available in the literature suggest that common symptoms include developmental delay, intellectual disability, and developmental regression.

Clinical characteristics of patients with cerebellar ataxia associated with anti-GAD antibodies

Arquivos de Neuro-Psiquiatria
The enzyme glutamic acid decarboxylase (GAD), present in GABAergic neurons and in pancreatic beta cells, catalyzes the conversion of gamma-aminobutyric acid (GABA).

Genetic Variants of Na+,K+‐ATPase Associated With Neurological Disorders: A Systematic Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Neurological disorders encompass a wide range of severe symptoms and manifestations, many of which are associated with genetic variants that affect ionic homeostasis. Na+,K+‐ATPase, a transmembrane enzyme responsible for maintaining electrochemical gradients in cells, plays a crucial role in neuronal excitability and brain function.

Investigating ITM2B‐associated ataxia in a Taiwanese cerebellar ataxia cohort

Annals of Clinical and Translational Neurology
Objective The genetic causes of a significant number of patients with cerebellar ataxia remain unsolved. Variations in the ITM2B gene, typically linked to dominantly inherited dementia, can sometimes present with cerebellar ataxia as an early symptom ...

Temporal and spatial variability in speakers with Parkinson's Disease and Friedreich's Ataxia [PDF]

, 2008
Speech variability in groups of speakers with Parkinson's disease (PD) and with Friedreich's ataxia was compared with healthy controls. Speakers repeated the same phrase 20 times at one of two rates (fast or habitual).

The EXPLAIN Study: Exploring Arthrogryposis Multiplex Congenita in Adults in Norway — A Description of Demographic, Medical, and Neurological Findings

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis Multiplex Congenita (AMC) encompasses several hundred conditions with diverse genetic, pathophysiological, and clinical origins. The overarching EXPLAIN study explores underlying causes and implications of AMC and represents the largest clinical cohort of adults with AMC reported to date.

Spinocerebellar ataxias: genotype-phenotype correlations in 104 Brazilian families

Clinics, 2012
OBJECTIVE: Spinocerebellar ataxias are neurodegenerative disorders involving the cerebellum and its connections. There are more than 30 distinct subtypes, 16 of which are associated with an identified gene.

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.

Patient‐Derived Fibroblasts as a Clinically Relevant Model of Kearns–Sayre Syndrome

Annals of Neurology, EarlyView.
Objective Kearns–Sayre syndrome (KSS) is characterized by single large‐scale mitochondrial DNA deletions and by severe early‐onset clinical manifestations with neurological involvement. Reliable disease models, as well as validated biomarkers or effective treatments, are lacking.
