KCNJ4 variants disrupt inward‐rectifier potassium channel function and cause refractory epilepsy

Epilepsia, Volume 67, Issue 6, Page 3199-3210, June 2026.
Abstract Objective Epilepsy is a common neurological disorder with a strong genetic basis, most frequently arising from ion channel dysfunction. Although multiple inwardly rectifying potassium (Kir) channels have been implicated in epileptogenesis, the contribution of KCNJ4, which encodes the Kir2.3 channel, has not previously been established in human

A Modified DSC-Based Grid Synchronization Method for a High Renewable Penetrated Power System Under Distorted Voltage Conditions

Energies, 2019
With the increasing penetration of renewable energy, a weak grid with declining inertia and distorted voltage conditions becomes a significant problem for wind and solar energy integration. Grid frequency is prone to deviate from its nominal value.

Expanding African contributions to ClinVar through genetic counselor‐led variant curation

Journal of Genetic Counseling, Volume 35, Issue 3, June 2026.
Abstract Global variant databases such as ClinVar are vital in linking genetic variation to clinical significance and enabling shared interpretation across laboratories. However, African genetic variants remain underrepresented, comprising under 2% of global ClinVar submissions.
