Editing KCNH1

'''KCNH1''' is a gene that encodes a protein known as [[potassium voltage-gated channel subfamily H member 1]]. This protein is a member of the [[voltage-gated potassium channel]] family, which plays a crucial role in the [[electrical activity]] of various cell types, including neurons and muscle cells.

== Function ==
The KCNH1 gene provides instructions for making a protein that forms a channel across the cell membrane. This channel, known as the [[Ether-à-go-go]] (EAG) channel, allows [[potassium ions]] to flow out of cells. The movement of potassium ions through these channels is critical for maintaining the normal functions of cells, particularly nerve cells (neurons) in the brain.

== Clinical significance ==
Mutations in the KCNH1 gene have been associated with [[Zimmerman-Laband syndrome]] and [[Temple-Baraitser syndrome]]. These are rare genetic disorders characterized by abnormalities in multiple body systems, including the nervous system. Mutations in the KCNH1 gene alter the function of the EAG channel, disrupting the flow of potassium ions in neurons. This disruption affects the normal electrical activity in the brain, leading to the neurological symptoms seen in these disorders.
