Long‐Term Follow‐Up of Patients With Mitochondrial Carbonic Anhydrase VA Deficiency. A Case Report and Literature Review

JIMD Reports, Volume 67, Issue 4, July 2026.
ABSTRACT Mitochondrial carbonic anhydrase VA (CA‐VA) deficiency is a rare inherited metabolic disorder caused by biallelic variants of the CA5A gene. It presents with hyperammonemia, lactic acidosis, and ketonuria, with or without hypoglycemia. We report the long‐term follow‐up of the first two reported cases of CA‐VA deficiency: a 16‐year‐old female ...

KCNJ4 variants disrupt inward‐rectifier potassium channel function and cause refractory epilepsy

Epilepsia, Volume 67, Issue 6, Page 3199-3210, June 2026.
Abstract Objective Epilepsy is a common neurological disorder with a strong genetic basis, most frequently arising from ion channel dysfunction. Although multiple inwardly rectifying potassium (Kir) channels have been implicated in epileptogenesis, the contribution of KCNJ4, which encodes the Kir2.3 channel, has not previously been established in human

Baseline characteristics and feasibility of clinical outcome measures in CDKL5 deficiency disorder: The CANDID observational study

Epilepsia, Volume 67, Issue 4, Page 1703-1721, April 2026.
Abstract Objective CDKL5 deficiency disorder (CDD) is a rare X‐linked developmental and epileptic encephalopathy caused by loss‐of‐function variants in the CDKL5 gene. Preclinical experiments using enzyme replacement or gene therapies show promise and could be transformative therapies.

Human CNTNAP1 Variants Associated With Severe Neurological Deficits: Additional Cases and Literature Review

Muscle &Nerve, Volume 73, Issue 4, Page 517-526, April 2026.
ABSTRACT CNTNAP1 encodes the Contactin‐Associated Protein 1 (CNTNAP1), also known as Caspr1, which is a transmembrane protein critical for nervous system function. CNTNAP1 is localized to the paranodal regions of all myelinated axons, flanking either side of the node of Ranvier.

A Comprehensive Overview of the Clinical, Electrophysiological, and Neuroimaging Features of BPAN: Insights From a New Case Series

Annals of Clinical and Translational Neurology, Volume 13, Issue 3, Page 453-465, March 2026.
ABSTRACT Background Neurodegeneration with brain iron accumulation (NBIA) comprises a genetically and clinically heterogeneous group of rare neurological disorders characterized particularly by iron accumulation in the basal ganglia. To date, 15 genes have been associated with NBIA.

Maternal Child‐Directed Speech Toward Children With Infantile Spasm or West Syndrome

International Journal of Language &Communication Disorders, Volume 61, Issue 2, March/April 2026.
ABSTRACT Background Maternal child‐directed speech (MCDS) plays a critical role in early language and communicative development, yet little is known about how it adapts to neurodevelopmental conditions such as Infantile Spasms/West Syndrome (WS), particularly when co‐occurring with intellectual disability (WID) or autism spectrum disorder (WASD).
