Heterozygous KCNJ10 variants affecting Kir4.1 channel cause paroxysmal kinesigenic dyskinesia
Abstract Background Paroxysmal kinesigenic dyskinesia is the representative form of paroxysmal dyskinesia, and its mechanism is unclear. Although paroxysmal kinesigenic dyskinesia is mostly attributed to genetic factors, more than 60% of paroxysmal kinesigenic dyskinesia cases are of uncertain mutations.

Mapping Satellite Glial Cell Heterogeneity Reveals Distinct Spatial Organization and Implies Functional Diversity in the Dorsal Root Ganglion. [PDF]
Four distinct satellite glial cell subtypes are identified in mouse dorsal root ganglia using single‐cell RNA sequencing and spatial validation. These subtypes show unique marker profiles and anatomical distributions. Human dorsal root ganglia display layered perisomatic organization with differential marker expression.

Development of the stria vascularis and potassium regulation in the human fetal cochlea : insights into hereditary sensorineural hearing loss [PDF]
Sensorineural hearing loss (SNHL) is one of the most common congenital disorders in humans, afflicting one in every thousand newborns. The majority is of heritable origin and can be divided in syndromic and nonsyndromic forms. Knowledge of the expression

Oligodendrocyte-encoded Kir4.1 function is required for axonal integrity
Glial support is critical for normal axon function and can become dysregulated in white matter (WM) disease. In humans, loss-of-function mutations of KCNJ10, which encodes the inward-rectifying potassium channel KIR4.1, causes seizures and progressive ...

Role of collecting duct principal cell NOS1β in sodium and potassium homeostasis
The nitric oxide (NO)‐generating enzyme, NO synthase‐1β (NOS1β), is essential for sodium (Na+) homeostasis and blood pressure control. We previously showed that collecting duct principal cell NOS1β is critical for inhibition of the epithelial sodium ...

Lack of significant association between mutations of KCNJ10 or FOXI1 and SLC26A4 mutations in pendred syndrome/enlarged vestibular aqueducts [PDF]
Pendred syndrome is a common autosomal recessive disorder causing deafness. Features include sensorineural hearing impairment, goitre, enlarged vestibular aqueducts (EVA) and occasionally Mondini dysplasia.
