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.58G>A (p.E20K) alteration is located in exon 2 (coding exon 1) of the TRPV2 gene. This alteration results from a G to A substitution at nucleotide position 58, causing the glutamic acid (E) at amino acid position 20 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
