Genes affected
TACR2 (HGNC:11527): (tachykinin receptor 2) 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 neuropeptide substance K, also referred to as neurokinin A. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.221A>G (p.N74S) alteration is located in exon 1 (coding exon 1) of the TACR2 gene. This alteration results from a A to G substitution at nucleotide position 221, causing the asparagine (N) at amino acid position 74 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
