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.475G>A (p.D159N) alteration is located in exon 4 (coding exon 3) of the TRPV2 gene. This alteration results from a G to A substitution at nucleotide position 475, causing the aspartic acid (D) at amino acid position 159 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
