Genes affected

TRPV2 (HGNC:18082): (transient receptor potential cation channel subfamily V member 2) This gene encodes an ion channel that is activated by high temperatures above 52 degrees Celsius. The protein may be involved in transduction of high-temperature heat responses in sensory ganglia. It is thought that in other tissues the channel may be activated by stimuli other than heat.
