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.

Collection Method: clinical testing

The c.218G>A (p.R73Q) alteration is located in exon 3 (coding exon 2) of the TRPV2 gene. This alteration results from a G to A substitution at nucleotide position 218, causing the arginine (R) at amino acid position 73 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
