Disease relevance of HCRTR2

 

Psychiatry related information on HCRTR2

 

High impact information on HCRTR2

  • The risk of cluster headache (CH) is associated with the G-allele of the G1246A polymorphism in the hypocretin receptor 2 (HCRTR2) gene [5].
  • While the HCRTR2 1246G allele was significantly associated with CH in this group, treatment outcomes with triptans, oxygen, verapamil and corticosteroids remained unaffected [5].
  • Positional cloning of the gene responsible for a canine model of narcolepsy revealed that this disease is caused by mutations in hypocretin receptor type 2 [6].
