Heterozygous variants in AP4S1 are not associated with a neurological phenotype

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Biallelic loss‐of‐function variants in AP4S1 cause childhood‐onset hereditary spastic paraplegia. A recent report suggested that heterozygous AP4S1 variants lead to a syndrome of lower limb spasticity and dysregulation of sphincter function. We critically evaluate this claim against clinical observations in 28 heterozygous carriers of the same

Short-term and long-term changes in seizure frequency and neurocognitive status in pediatric patients after surgery for mixed neuronal-glial brain tumors

open access: yesЭпилепсия и пароксизмальные состояния, 2022
Background. Neuronal and mixed neuronal-glial tumors are rare brain tumors that are most commonly observed in pediatric patients. The main clinical manifestations are presented by epilepsy substantially affecting child’s physical and neurocognitive ...

Quantum Data-Syndrome Codes [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, vol. 38, no. 3, pp. 449-462, March 2020, 2019
Performing active quantum error correction to protect fragile quantum states highly depends on the correctness of error information--error syndromes. To obtain reliable error syndromes using imperfect physical circuits, we propose the idea of quantum data-syndrome (DS) codes that are capable of correcting both data qubits and syndrome bits errors.

Clinical impact and safety of brain biopsy in unexplained central nervous system disorders: a real‐world cohort study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective A substantial part of central nervous system (CNS) disorders remains unexplained, despite various new and minimally invasive diagnostic techniques. Within this rapidly developing diagnostic field, the precise role of brain biopsy is unknown.

The molecular genetics of RASopathies: An update on novel disease genes and new disorders

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, Volume 190, Issue 4, Page 425-439, December 2022., 2022
Abstract Enhanced signaling through RAS and the mitogen‐associated protein kinase (MAPK) cascade underlies the RASopathies, a family of clinically related disorders affecting development and growth. In RASopathies, increased RAS‐MAPK signaling can result from the upregulated activity of various RAS GTPases, enhanced function of proteins positively ...

UDP‐glucose dehydrogenase variants cause dystroglycanopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract UDP‐glucose dehydrogenase (UGDH) variants have been associated with hypotonia, developmental delay, and epilepsy. We report the first pathologic evidence of dystroglycanopathy in siblings with UGDH variants. Both presented around 6 months with developmental delay and elevated creatinine kinase.

Clinical overview on RASopathies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, Volume 190, Issue 4, Page 414-424, December 2022., 2022
Abstract RASopathies comprise a group of clinically overlapping developmental disorders caused by genetic variations affecting components or modulators of the RAS‐MAPK signaling cascade, which lead to dysregulation of signal flow through this pathway.

Effect of Cannabidiol on Drop Seizures in the Lennox–Gastaut Syndrome

open access: yesNew England Journal of Medicine, 2018
Background Cannabidiol has been used for treatment‐resistant seizures in patients with severe early‐onset epilepsy. We investigated the efficacy and safety of cannabidiol added to a regimen of conventional antiepileptic medication to treat drop seizures ...

Capturing what matters: Patient‐reported LGI1‐ANTibody encephalitis outcome RatiNg scale (LANTERN)

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Background LGI1‐antibody encephalitis (LGI1‐Ab‐E) is a common form of autoimmune encephalitis where most patients demonstrate ‘good’ clinician‐rated outcomes. However, more targeted questionnaires reveal numerous debilitating symptoms for many years.
