Clinical characteristics and lateralization of the horizontal semicircular canal light cupula
Frontiers in NeurologyIntroductionPositional vertigo and nystagmus are the main symptoms and signs of dizziness, respectively. Despite the clinical utility of the supine roll test (SRT) and null point (NP) in diagnosing light cupula, a type of positional vertigo, there exists

De Novo Variants in PPFIA2 in Individuals With Neurodevelopmental Disorders
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Liprin‐α2, encoded by PPFIA2, belongs to the family of Liprin‐α proteins which constitute major synaptic scaffolds participating in the assembly and maturation of synapses. Heterozygous de novo variants in PPFIA2 were identified by exome or genome sequencing in two unrelated individuals with a neurodevelopmental disorder.
