Absence of iron-responsive element-binding protein 2 causes a novel neurodegenerative syndrome.

Brain 2019 Mar 26. Epub 2019 Mar 26.

Division of Clinical and Metabolic Genetics, Department of Paediatrics, The Hospital for Sick Children, University of Toronto, Toronto, Ontario, Canada.

Disruption of cellular iron homeostasis can contribute to neurodegeneration. In mammals, two iron-regulatory proteins (IRPs) shape the expression of the iron metabolism proteome. Targeted deletion of Ireb2 in a mouse model causes profoundly disordered iron metabolism, leading to functional iron deficiency, anemia, erythropoietic protoporphyria, and a neurodegenerative movement disorder.

Movement disorders phenomenology in focal motor seizures.

Parkinsonism Relat Disord 2018 Oct 16. Epub 2018 Oct 16.

Department of Human Neurosciences, Sapienza University of Rome, Rome, Italy; IRCSS Neuromed, Pozzilli, IS, Italy.

Introduction: Although focal motor seizures may resemble one or more movement disorders their phenomenology and prevalence remain uncertain.

Methods: To examine the extent to which focal motor seizures can present with a phenomenology fulfilling diagnostic criteria for movement disorders, 100 consecutive patients with focal motor seizures were rated by movement disorders experts, epileptologists, and general neurologists.

Results: A focal motor seizure phenomenologically manifested as a defined movement disorder in 29% of the patients from a consecutive video-EEG documented cohort as per consensus among experts: myoclonus and dystonia (10 and 9 cases, respectively) were the most common movement disorders, followed by chorea (4), stereotypies (3) myoclonus-dystonia (2), and tremor (1).

Executive impairment is associated with unawareness of neuropsychiatric symptoms in premanifest and early Huntington's disease.

Neuropsychology 2018 Nov 13;32(8):958-965. Epub 2018 Sep 13.

Monash Institute of Cognitive and Clinical Neurosciences, School of Psychological Sciences, Monash University.

Objective: Unawareness of neuropsychiatric symptoms appears to be common in Huntington's disease (HD), but the clinical correlates of unawareness are unclear. Identifying predictors of unawareness is important for improving diagnosis of neuropsychiatric symptoms, and cognitive impairment, specifically executive impairment, may be a potential important predictor of unawareness. The authors examined whether unawareness of neuropsychiatric symptoms is more common in early HD compared to premanifest HD, and whether executive task performance was associated with awareness, independent of demographic, motor or mood variables.

Reverse pre-symptomatic testing for Huntington disease: double disclosure when 25% at-risk children reveal the genetic status to their parent.

Eur J Hum Genet 2019 01 11;27(1):22-27. Epub 2018 Sep 11.

APHP, Genetic Department, Pitié-Salpêtrière University Hospital, Paris, France.

Predictive testing for Huntington disease (HD) in 25% at-risk individuals is testing with full knowledge, and sometimes assuming, that the parent does not want to know his status. The goal of this study was to understand: (1) the differences in the motivation between 25% and 50% at-risk individuals to be tested and (2) the consequences of "double disclosure", including parental reactions. Test requests from 25% at-risk individuals were rare (155/1611, 10%). Read More

Inherited and Acquired Choreas.

Semin Pediatr Neurol 2018 04 23;25:42-53. Epub 2018 Feb 23.

Department of Neurology, Boston Children's Hospital, Boston, MA; Department of Neurology, Massachusetts General Hospital, Boston, MA. Electronic address:

Chorea is a symptom of a broad array of genetic, structural, and metabolic disorders. While chorea can result from systemic illness and damage to diverse brain structures, injury to the basal ganglia, especially the putamen or globus pallidus, appears to be a uniting features of these diverse neuropathologies. The timing of onset, rate of progression, and the associated neurological or systemic symptoms can often narrow the differential diagnosis to a few disorders. Read More

A whole brain longitudinal study in the YAC128 mouse model of Huntington's disease shows distinct trajectories of neurochemical, structural connectivity and volumetric changes.

Hum Mol Genet 2018 06;27(12):2125-2137

Institute of Nuclear Science Applied to Health, University of Coimbra, 3000-548 Coimbra, Portugal.

Huntington's disease (HD) is a neurodegenerative disorder causing cognitive and motor impairments, evolving to death within 15-20 years after symptom onset. We previously established a mouse model with the entire human HD gene containing 128 CAG repeats (YAC128) which accurately recapitulates the natural history of the human disease. Defined time points in this natural history enable the understanding of longitudinal trajectories from the neurochemical and structural points of view using non-invasive high-resolution multi-modal imaging.

Receptor for Advanced Glycation End Products (RAGE) is Expressed Predominantly in Medium Spiny Neurons of tgHD Rat Striatum.

Neuroscience 2018 06 4;380:146-151. Epub 2018 Apr 4.

Jan and Dan Duncan Neurological Research Institute, Texas Children Hospital, Department of Neuroscience, Baylor College of Medicine, 1250 Moursund St, Houston, TX 77030, United States. Electronic address:

Receptor for advanced glycation end products (RAGE) is a multi-ligand receptor involved in the pathology of several progressive neurodegenerative disorders including Huntington's disease (HD). We previously showed that the expression of RAGE and its colocalization with ligands were increased in the striatum of HD patients, increasing with grade severity, and that the pattern of RAGE expression coincided with the medio-lateral pattern of neurodegeneration. However, the exact role of RAGE in HD remains elusive. Read More

Benign hereditary chorea and deletions outside NKX2-1: What's the role of MBIP?

Eur J Med Genet 2018 Oct 3;61(10):581-584. Epub 2018 Apr 3.

Molecular Neurogenetics, Foundation IRCCS Neurological Institute Besta, Milan, Italy; Department of Pathophysiology and Transplantation, University of Milan, Milan, Italy. Electronic address:

Heterozygous point mutations or deletions of the NKX2-1 gene cause benign hereditary chorea (BHC) or a various combinations of primary hypothyroidism, respiratory distress and neurological disorders. Deletions proximal to, but not encompassing, NKX2-1 have been described in few subjects with brain-lung-thyroid syndrome. We report on a three-generation Italian family, with 6 subjects presenting BHC and harboring a genomic deletion adjacent to NKX2-1 and including the gene MBIP, recently proposed to be relevant for the pathogenesis of brain-lung-thyroid syndrome.
