A Novel Constitutional TUBB Variant Associated With Familial Malformations of Cortical Development

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Most pathogenic tubulin variants arise de novo in sporadic patients, causing severe brain malformations and significant neurodevelopmental impairment. The resulting reproductive disadvantage typically prevents these mutations from being transmitted to offspring.

First Report of Uniparental Isodisomy of Chromosome 15 Revealing Angelman Syndrome and Microphthalmia Associated With a Novel Homozygous ALDH1A3 Variant

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Paternal isodisomy of chromosome 15 (iUPD15) is a recognized cause of Angelman syndrome (AS), accounting for approximately 2%–5% of cases. Additionally, another recognized consequence of iUPD is the unmasking of autosomal recessive disorders. However, reports of recessive disorders resulting from iUPD15 remain scarce in the literature.

Expanding the Phenotypic Spectrum of TXNDC15‐Related Ciliopathies to Include Joubert Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic loss‐of‐function variants in TXNDC15 are a known cause of the perinatally lethal ciliopathy Meckel syndrome (MKS). TXNDC15 encodes an endoplasmic reticulum (ER)‐resident thioredoxin‐domain protein required for ciliary transition zone integrity.

Systematic Review of Females With Intellectual Disability and MECP2 Duplication

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT MECP2 Duplication Syndrome (MDS) is a rare, X‐linked neurodevelopmental disorder typically affecting males. Females with MDS have been reported and are compiled here. We conducted a systematic review (PROSPERO CRD420250652426) of PubMed, EMBASE, and Google Scholar extracting individual participant data.

Extending the ATP9A‐Related Phenotypic Spectrum: Indication of Schizophrenia Susceptibility

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT ATP9A, which belongs to the P4‐ATPase family of proteins, is involved in the efficient transport of vesicles from the Golgi apparatus to the plasma membrane, as well as the release of extracellular vesicles from human cells. In 2021, a loss‐of‐function variant of this gene was identified as being associated with a recessive neurodevelopmental ...

The classification and differential diagnosis of absence seizures with short-term video-EEG monitoring during childhood

open access: yesThe Turkish Journal of Pediatrics, 2012
Absence seizures are idiopathic epilepsies characterized by impairment of consciousness and generalized 2.5-4 Hz spike and slow wave discharges.

Concordance of clinical forms of epilepsy in families with several affected members

open access: yes, 1993
Evidence for genetic heterogeneity in epilepsy is strong. We evaluated the concordance of clinical forms in the same family in a series of family with several cases of idiopathic epilepsy.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Expanded characterization of the valproic acid zebrafish larval model of autism spectrum disorder: Insights into dysregulation in the gut

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Meticulous calculation of zebrafish‐equivalent therapeutic valproic acid (VPA) dosage maximized the translational value of the data. Hyposerotonergic tone underpinned an anxiety‐like outcome as a core symptom of autism spectrum disorder (ASD). Compartment‐specific dopaminergic and serotonergic dysregulation in the brain versus gut provided mechanistic ...

T Cell‐Mediated Targeting of Interneurons in Mice Shapes Hippocampal Remodeling and Epilepsy

open access: yesAnnals of Neurology, EarlyView.
Objective Autoimmune encephalitis (AE) is associated with autoantibodies targeting distinct neuronal populations. In AE, antibodies against glutamate decarboxylase 65 (GAD65), expressed in GABAergic interneurons, are frequently detected. In GAD65‐AE, hippocampal biopsies often show infiltrates of CD8+ cytotoxic T cells (CTLs), suggesting a prominent T ...
