Refined linkage disequilibrium and physical mapping of the gene locus for X-linked dystonia-parkinsonism (DYT3).

, 1999
X-linked dystonia-parkinsonism (XDP) is a recessive disorder characterized by generalized dystonia with some patients exhibiting parkinsonism. The disease gene, DYT3, is located between DXS453 (DXS993) and DXS559, and strongest linkage disequilibrium is ...

Missense Variants in the A Isoform of FGF13 as a Novel Cause of Paroxysmal Dyskinesia

Movement Disorders, EarlyView.
Abstract Background Pathogenic variants within the unique N‐terminal inactivation particle of FGF13 isoform A (FGF13A) have so far been associated only with an X‐linked dominant epileptic encephalopathy (DEE). Objective The aim was to expand the clinical and molecular spectrum of FGF13A‐related disorder.

Motor assessment of X-linked dystonia parkinsonism via machine-learning-based analysis of wearable sensor data

Scientific Reports
X-linked dystonia parkinsonism (XDP) is a neurogenetic combined movement disorder involving both parkinsonism and dystonia. Complex, overlapping phenotypes result in difficulties in clinical rating scale assessment.

De novo variants in WDR45 underlie beta‐propeller protein‐associated neurodegeneration in five independent families

Molecular Genetics & Genomic Medicine, 2020
Background Beta‐propeller protein‐associated neurodegeneration (BPAN) is a rare, X‐linked dominant neurodegenerative disease mainly characterized by developmental delay, intellectual disability, epilepsy in childhood and dystonia, parkinsonism, dementia ...

Neurodevelopmental Disorder with Dystonia and Chorea Linked to De Novo Variants in the Splicing Regulator SRRM4

Movement Disorders, EarlyView.
Abstract Background SRRM4 is an exclusively neural‐expressed splicing‐factor gene not yet associated with a monogenic condition. Objective We sought to delineate movement disorders caused by SRRM4 variants. De novo splice‐donor‐site variants at position +2 of intron 5 of SRRM4 (c.464+2T>C, c.464+2T>A) occurred in three unrelated patients with dystonia ...

Validation of a screening questionnaire for X‐linked dystonia parkinsonism: The first phase of the population‐based prevalence study of X‐linked dystonia parkinsonism in Panay [PDF]

Neurology and Clinical Neuroscience, 2017
AbstractBackgroundThe current prevalence of X‐linked dystonia parkinsonism is not known. No screening tool for the condition exists. By developing a screening questionnaire, the present study is intended to be the first step in identifying the prevalence of the disease.AimTo develop and validate a simple, easy to use, community‐based, screening ...

Basal ganglia function in parkinsonism and dystonia [PDF]

, 2022
Parkinsonism and dystonia are movement disorders linked with abnormal function of the basal ganglia. The most common cause of parkinsonism, Parkinson’s disease (PD), is caused by loss of dopaminergic neurons in the nigrostriatal tract, leading to ...

Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

Movement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

Heterogenous Neuropathology in a Pedigree with RAB39B‐Related Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background In 2015, we reported a family with Parkinson's disease resulting from the RAB39B p.G192R (c.574G>A) variant. Since then, two affected brothers from the family have undergone autopsy. Objectives To characterize neuropathological findings, assess intracellular distribution of RAB39B protein, and examine the effect of p.G192R on α ...

Defects in the striatal neuropeptide Y system in X-linked dystonia-parkinsonism [PDF]

Brain, 2013
Neuropeptide Y is a novel bioactive substance that plays a role in the modulation of neurogenesis and neurotransmitter release, and thereby exerts a protective influence against neurodegeneration. Using a sensitive immunohistochemical method with a tyramide signal amplification protocol, we performed a post-mortem analysis to determine the striatal ...
