Article Synopsis
  • RORA is a gene linked to the development and function of the cerebellum, and this study explores the largest group of individuals with RORA-related neurodevelopmental disorders (RORA-NDD).
  • The study involved 40 participants with various pathogenic variants of RORA, revealing a range of clinical features including developmental and intellectual disabilities, as well as cerebellar symptoms that can vary in onset and severity.
  • Findings indicate that certain missense variants are associated with more severe cerebellar issues, and common elements of RORA-NDD include developmental disabilities, cerebellar symptoms, and different types of myoclonic epilepsy.

Background: Febrile seizures (FSs) are the most common form of epilepsy in children aged between six months and five years. The exact cause is unknown, but several studies have demonstrated the importance of genetic predisposition, with increasing involvement of receptors and ion channels. The present study aims to identify novel pathogenic variants in Italian patients with FSs.

Doublecortin, encoded by the gene, plays a crucial role in the neuronal migration process during brain development. Pathogenic variants of the gene are the major causes of the "lissencephaly (LIS) spectrum", which comprehends a milder phenotype like Subcortical Band Heterotopia (SBH) in heterozygous female subjects. We performed targeted sequencing in three unrelated female cases with SBH.

Article Synopsis
  • * The study focused on an Italian family with four affected members (the mother and three siblings) who exhibited myotonia, along with two of them having JME; genetic testing revealed a shared variant in the SCN4A gene among those affected.
  • * Findings suggest that the myotonia and epilepsy in this family may stem from the same genetic mutation in the SCN4A gene, indicating that

Identifying genetic risk factors for highly heterogeneous disorders like epilepsy remains challenging. Here, we present the largest whole-exome sequencing study of epilepsy to date, with >54,000 human exomes, comprising 20,979 deeply phenotyped patients from multiple genetic ancestry groups with diverse epilepsy subtypes and 33,444 controls, to investigate rare variants that confer disease risk. These analyses implicate seven individual genes, three gene sets, and four copy number variants at exome-wide significance.

Recently, a novel pathogenic variant in Annexin A1 protein (c.4G > A, p.Ala2Thr) has been identified in an Iranian consanguineous family with autosomal recessive parkinsonism.

Introduction: Progranulin (PGRN) is a secreted glycoprotein encoded in humans by the GRN gene, located on chromosome 17q21. Several nonsense and missense pathogenetic GRN mutations have been described.

Objective: We herein describe two sisters carrying a rare GRN mutation with extremely different clinical features and family history of dementia and behavioral disorders, with a novel presentation with stridor and dysphonia.
