  Potassium channel subfamily K member 18 (KCNK18), also known as TWIK-related spinal cord potassium channel (TRESK) or $K_{2P}18.1$ is a protein that in humans is encoded by the KCNK18 gene. $K_{2P}18.1$ is a potassium channel containing two pore-forming P domains.
  
  A flaw in this gene could help trigger migraine headaches. If the gene does not work properly, environmental factors can more easily trigger pain centres in the brain and cause a severe headache.
