KCNH7 encodes a pore-forming alpha subunit of voltage-gated inwardly rectifying potassium channels, exhibiting faster activation and deactivation kinetics with slow inactivation at membrane potentials positive to 240 mV, resulting in weak inward rectification 1. The channel operates through partial inductor-like gating dynamics, displaying rapid opposing conductance changes followed by slow activation in response to depolarizing voltage steps 2. KCNH7 has been implicated in several neurological conditions. A non-synonymous variant (p.Arg394His) showed association with bipolar spectrum disorder in Amish populations, altering steady-state voltage dependence and activation kinetics in neuronal cells while maintaining normal channel expression and trafficking 3. The gene has been identified as a potential biomarker associated with malignant cell proliferation in glioblastoma 4. Additionally, KCNH7 variants showed association with the metabolic subtype of polycystic ovary syndrome 5. Microdeletions encompassing KCNH7 at chromosome 2.2q24.3 are associated with intellectual disability, developmental delays, and neurological features 6. However, plasma KCNH7 levels showed no significant differences between fibromyalgia patients and controls 7.
