Genes affected
TACR3 (HGNC:11528): (tachykinin receptor 3) This gene belongs to a family of genes that function as receptors for tachykinins. Receptor affinities are specified by variations in the 5'-end of the sequence. The receptors belonging to this family are characterized by interactions with G proteins and 7 hydrophobic transmembrane regions. This gene encodes the receptor for the tachykinin neurokinin 3, also referred to as neurokinin B. [provided by RefSeq, Jul 2008]
TACR3-AS1 (HGNC:55593): (TACR3 antisense RNA 1)

The c.1273C>T (p.R425W) alteration is located in exon 5 (coding exon 5) of the TACR3 gene. This alteration results from a C to T substitution at nucleotide position 1273, causing the arginine (R) at amino acid position 425 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
