Genes affected

TRPA1 (HGNC:497): (transient receptor potential cation channel subfamily A member 1) The structure of the protein encoded by this gene is highly related to both the protein ankyrin and transmembrane proteins. The specific function of this protein has not yet been determined; however, studies indicate the function may involve a role in signal transduction and growth control. [provided by RefSeq, Jul 2008]

The c.3166T>C (p.F1056L) alteration is located in exon 27 (coding exon 27) of the TRPA1 gene. This alteration results from a T to C substitution at nucleotide position 3166, causing the phenylalanine (F) at amino acid position 1056 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
