Genes affected

TAC1 (HGNC:11517): (tachykinin precursor 1) This gene encodes four products of the tachykinin peptide hormone family, substance P and neurokinin A, as well as the related peptides, neuropeptide K and neuropeptide gamma. These hormones are thought to function as neurotransmitters which interact with nerve receptors and smooth muscle cells. They are known to induce behavioral responses and function as vasodilators and secretagogues. Substance P is an antimicrobial peptide with antibacterial and antifungal properties. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2014]

The c.322G>A (p.G108S) alteration is located in exon 6 (coding exon 5) of the TAC1 gene. This alteration results from a G to A substitution at nucleotide position 322, causing the glycine (G) at amino acid position 108 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
