Genes affected

TRPV1 (HGNC:12716): (transient receptor potential cation channel subfamily V member 1) Capsaicin, the main pungent ingredient in hot chili peppers, elicits a sensation of burning pain by selectively activating sensory neurons that convey information about noxious stimuli to the central nervous system. The protein encoded by this gene is a receptor for capsaicin and is a non-selective cation channel that is structurally related to members of the TRP family of ion channels. This receptor is also activated by increases in temperature in the noxious range, suggesting that it functions as a transducer of painful thermal stimuli in vivo. Four transcript variants encoding the same protein, but with different 5' UTR sequence, have been described for this gene. [provided by RefSeq, Jul 2008]

The c.1667C>A (p.T556N) alteration is located in exon 10 (coding exon 10) of the TRPV1 gene. This alteration results from a C to A substitution at nucleotide position 1667, causing the threonine (T) at amino acid position 556 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
