Dravet syndrome (DS) is a developmental and epileptic encephalopathy (DEE) that begins in the first year of life. While most cases of DS are caused by variants in SCN1A, variants in SCN1B, encoding voltage-gated sodium channel β1 subunits, are also linked to DS or to the more severe early infantile DEE. Both disorders fall under the OMIM term DEE52.

Dynein Cytoplasmic 1 Heavy chain 1 (-related disorders are a spectrum of conditions including neurodevelopmental disorders, congenital brain malformations, and neuromuscular diseases. These clinical features may co-occur, with four main disease entities including epilepsy with developmental epileptic encephalopathy such as infantile epileptic spasms syndrome (IESS) and Lennox-Gastaut syndrome (LGS), axonal Charcot-Marie-Tooth disease type 2O, spinal muscular atrophy with lower extremity-predominance (SMALED), and congenital cortical malformations. Epilepsy associated with this disorder often becomes drug-resistant and requires multiple medications and, in some cases, non-pharmacological treatments.

Neuronal ceroid lipofuscinoses (NCLs) are genetically heterogeneous neurodegenerative disorders, characterized by progressive cognitive and motor decline, epilepsy, visual impairment, and shortened life-expectancy. CLN6-related NCLs include both late-infantile and adult myoclonic form. We report a 21-year-old patient, with mild developmental delay, who developed occipital seizures at 14 years, and subsequently cognitive decline, cortical myoclonus, and photosensitivity at low and higher frequencies.

The infantile neuronal ceroid lipofuscinosis, also called CLN1 disease, is a fatal neurodegenerative disease caused by mutations in the CLN1 gene encoding palmitoyl protein thioesterase 1 (PPT1). Identifying the depalmitoylation substrates of PPT1 is crucial for understanding CLN1 disease. In this study, we found that GABAR, the critical synaptic protein essential for inhibitory neurotransmission, is a substrate of PPT1.

Infantile dural arteriovenous fistula (IDAVF) is a rare complex dural arteriovenous fistulas. This study is to provide a comprehensive understanding of the angioarchitecture of arteriovenous shunts in IDAVFs and planning endovascular treatment. Five cases of IDAVF and a literature review were analyzed to characterize the shunt patterns of IDAVFs in terms of anatomic relations to the arterial feeder, sinuses, and cortical veins.
