Biallelic Nonsense Variants in NEFL May Cause a Non‐Length‐Dependent Neuropathy With Temporal Dispersion on Nerve Conduction Studies

Journal of the Peripheral Nervous System, Volume 31, Issue 2, June 2026.
ABSTRACT Background and Aims Pathogenic variants in NEFL, the gene that encodes the light polypeptide subunit of neurofilaments, are an uncommon cause of autosomal recessive Charcot‐Marie‐Tooth (CMT) disease. In this study, we describe the clinical and electrophysiological features of two families with early‐onset CMT carrying nonsense variants in the ...

Genetic and Phenotypic Features of the Five Known Polyaminopathies: A Critical Narrative Review

American Journal of Medical Genetics Part A, Volume 200, Issue 5, Page 993-1003, May 2026.
ABSTRACT Polyaminopathies are a recently described family of rare genetic neurodevelopmental disorders. Polyaminopathies disrupt the biosynthesis of the primary polyamines: putrescine, spermidine, and spermine. Snyder–Robinson syndrome results from hemizygous loss‐of‐function variants in the spermine synthase (SMS) gene, resulting in decreased or ...

The Clinical Spectrum and Neurodevelopmental Pathogenesis of KPTN‐Related Disorder in a Mouse Model

Annals of Neurology, Volume 99, Issue 5, Page 1287-1302, May 2026.
Objective Pathogenic variants in Kaptin (KPTN) cause KPTN‐related disorder (KRD). KPTN modulates mTOR signaling activation within the KICSTOR complex in response to cellular amino acid levels. We define the clinical spectrum and investigate the developmental pathogenesis of KRD.

The role of non-invasive camera technology for gait analysis in patients with vestibular disorders [PDF]

, 2017
Purpose of the study Current balance assessments performed in clinical settings do not provide objective measurements of gait. Further, objective gait analysis typically requires expensive, large and dedicated laboratory facilities.

Pathological Localization of Benign Paroxysmal Positional Vertigo. From Three-dimensional Analysis of Nystagmus.

Nippon Jibiinkoka Gakkai Kaiho, 1997
Although it has been speculated that benign paroxysmal positional vertigo (BPPV) derives from the utricle or posterior semicircular canal, the origin of BPPV is still controversial. In this study, we investigated the role of the utricle and semicircular canals (especially the vertical semicircular canal) relative to BPPV by three-dimensional analysis ...

A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

Clinical Anatomy, Volume 39, Issue 4, Page 436-460, May 2026.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

A Chinese X‐Linked Adrenoleukodystrophy Patient With Atypical Clinical Symptoms Contained an Undefined ABCD1 Mutation—A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT X‐linked adrenoleukodystrophy (X‐ALD) is a genetic peroxisome disorder linked to ABCD1 mutation, characterized by rapid and complex clinical symptoms. We here report a case of X‐ALD manifesting solely as dysarthria, associated with an undefined mutation in the ABCD1 gene, underscoring the necessity of atypical clinical symptoms in X‐ALD ...

Alexander's Law in Patients with Acute Vestibular Tone Asymmetry—Evidence for Multiple Horizontal Neural Integrators [PDF]

, 2018
Alexander's law (AL) states that the slow-phase velocity of spontaneous nystagmus of peripheral vestibular origin is dependent on horizontal gaze position, with greater velocity when gaze is directed in the fast-phase direction.
