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]
