SCN10A (Sodium Voltage-Gated Channel Alpha Subunit 10): SCN10A is a gene that encodes a member of the voltage-gated sodium channel family, which is essential for initiating and propagating action potentials in neurons and other excitable cells. This channel is primarily expressed in peripheral sensory neurons and plays a key role in pain sensation and nociception. Changes in SCN10A function or expression have been linked to various pain disorders, including neuropathic pain and inherited erythromelalgia, a condition marked by burning pain and redness in the extremities. The channel also contributes to cardiac electrophysiology.
