PRRT2 gene variant in a child with dysmorphic features, congenital microcephaly, and severe epileptic seizures: genotype-phenotype correlation? [PDF]

, 2019
BACKGROUND: Mutations in Proline-rich Transmembrane Protein 2 (PRRT2) have been primarily associated with individuals presenting with infantile epilepsy, including benign familial infantile epilepsy, benign infantile epilepsy, and benign myoclonus of ...

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Pathogenic Variants in Fucokinase Cause a Congenital Disorder of Glycosylation [PDF]

, 2018
FUK encodes fucokinase, the only enzyme capable of converting L-fucose to fucose-1-phosphate, which will ultimately be used for synthesizing GDP-fucose, the donor substrate for all fucosyltransferases.

NEAT1 Promotes Epileptogenesis in Tuberous Sclerosis Complex

Advanced Science, EarlyView.
The primary neurological manifestations of tuberous sclerosis complex (TSC) are intractable epilepsy and intellectual disability. NEAT1 is differentially expressed in TSC‐related epilepsy and influences neuronal excitability by regulating the PI3K/AKT/mTOR signaling pathway.

Why West? Comparisons of clinical, genetic and molecular features of infants with and without spasms. [PDF]

PLoS ONE, 2018
Infantile spasms are the defining seizures of West syndrome, a severe form of early life epilepsy with poorly-understood pathophysiology. We present a novel comparative analysis of infants with spasms versus other seizure-types and identify clinical ...

Multiplex ligation-dependent probe amplification (MLPA) analysis is an effective tool for the detection of novel intragenic PLA2G6 mutations: Implications for molecular diagnosis [PDF]

, 2010
Phospholipase associated neurodegeneration (PLAN) comprises a heterogeneous group of autosomal recessive neurological disorders caused by mutations in the PLA2G6 gene. Direct gene sequencing detects 85% mutations in infantile neuroaxonal dystrophy.

Long‐Read Genome Sequencing Establishes Biallelic Pathogenic Variants in DNM1 With Distinct Functional Effects as the Cause of Early Infantile Developmental and Epileptic Encephalopathy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous de novo and inherited biallelic pathogenic variants in DNM1 have been reported in association with autosomal dominant (AD) and autosomal recessive (AR) developmental and epileptic encephalopathy, respectively, due to aberrant dynamin function or expression, with each inheritance pattern associated with a different mechanism of ...

Epileptic spasms relapse is associated with response latency but not conventional attributes of post‐treatment EEG

Epilepsia Open
Objective Relapse of epileptic spasms after initial treatment of infantile epileptic spasms syndrome (IESS) is common. However, past studies of small cohorts have inconsistently linked relapse risk to etiology, treatment modality, and EEG features upon ...

X-Linked Infantile Spasms

Pediatric Neurology Briefs, 1997
Two unrelated families with X-linked infantile spasm syndrome were studied genetically by two-point and multipoint linkage analyses at the University Hospital Gasthuisberg, and Center for Human Genetics, University of Leuven, and University of Antwerp ...

GABRB3 mutations: a new and emerging cause of early infantile epileptic encephalopathy [PDF]

, 2016
The gamma-aminobutyric acid type A receptor β3 gene (GABRB3) encodes the β3-subunit of the gamma-aminobutyric acid type A (GABAA ) receptor, which mediates inhibitory signalling within the central nervous system.
