TMEM16C is involved in thermoregulation and protects rodent pups from febrile seizures.

Proc Natl Acad Sci U S A 2021 May;118(20)

Department of Physiology, University of California, San Francisco, CA 94158;

Febrile seizures (FSs) are the most common convulsion in infancy and childhood. Considering the limitations of current treatments, it is important to examine the mechanistic cause of FSs. Prompted by a genome-wide association study identifying TMEM16C (also known as ANO3) as a risk factor of FSs, we showed previously that loss of TMEM16C function causes hippocampal neuronal hyperexcitability [Feenstra , Nat.

Exploring Variances of White Matter Integrity and the Glymphatic System in Simple Febrile Seizures and Epilepsy.

Front Neurol 2021 21;12:595647. Epub 2021 Apr 21.

Department of Radiology, the First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China.

Simple febrile seizures (SFS) and epilepsy are common seizures in childhood. However, the mechanism underlying SFS is uncertain, and the presence of obvious variances in white matter (WM) integrity and glymphatic function between SFS and epilepsy remain unclear. Therefore, this study aimed to investigate the differences in WM integrity and glymphatic function between SFS and epilepsy. Read More

ACR Appropriateness Criteria® Seizures-Child.

J Am Coll Radiol 2021 May;18(5S):S199-S211

Specialty Chair, Riley Hospital for Children Indiana University, Indianapolis, Indiana.

In children, seizures represent an extremely heterogeneous group of medical conditions ranging from benign cases, such as a simple febrile seizure, to life-threatening situations, such as status epilepticus. Underlying causes of seizures also represent a wide range of pathologies from idiopathic cases, usually genetic, to a variety of acute and chronic intracranial or systemic abnormalities. This document discusses appropriate utilization of neuroimaging tests in a child with seizures. Read More

Modeling seizures in the Human Phenotype Ontology according to contemporary ILAE concepts makes big phenotypic data tractable.

Epilepsia 2021 May 5. Epub 2021 May 5.

Division of Neurology, Children's Hospital of Philadelphia, Philadelphia, PA, USA.

Objective: The clinical features of epilepsy determine how it is defined, which in turn guides management. Therefore, consideration of the fundamental clinical entities that comprise an epilepsy is essential in the study of causes, trajectories, and treatment responses. The Human Phenotype Ontology (HPO) is used widely in clinical and research genetics for concise communication and modeling of clinical features, allowing extracted data to be harmonized using logical inference.

Variant in A 3-Year-Old-An Expanding Spectrum?

Neurol Int 2021 Apr 29;13(2):184-189. Epub 2021 Apr 29.

"Carol Davila" University of Medicine and Pharmacy, 020021 Bucharest, Romania.

Glutamate, the major excitatory neurotransmitter, plays a ubiquitous role in most aspects of normal brain functioning. Its indispensable position is paradoxically doubled by a high excitotoxic potential following disruption of its dynamic equilibrium. Several lines of evidence have suggested the involvement of the glutamatergic N-methyl-D-aspartate receptor (NMDAR) in learning, memory formation, and human cognition. Read More

UNC13B variants associated with partial epilepsy with favourable outcome.

Brain 2021 Apr 20. Epub 2021 Apr 20.

Institute of Neuroscience and Department of Neurology of the Second Affiliated Hospital of Guangzhou Medical University, Guangzhou, China.

The unc-13 homolog B (UNC13B) gene encodes a presynaptic protein, mammalian uncoordinated 13-2 (Munc13-2), that is highly expressed in the brain-predominantly in the cerebral cortex-and plays an essential role in synaptic vesicle priming and fusion, potentially affecting neuronal excitability. However, the functional significance of UNC13B mutation in human disease is not known. In this study we screened for novel genetic variants in a cohort of 446 unrelated cases (families) with partial epilepsy without acquired causes by trio-based whole-exome sequencing. Read More
