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.

The c.505A>G (p.I169V) alteration is located in exon 4 (coding exon 3) of the TRPV2 gene. This alteration results from a A to G substitution at nucleotide position 505, causing the isoleucine (I) at amino acid position 169 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
