Genes affected

BDKRB2 (HGNC:1030): (bradykinin receptor B2) This gene encodes a receptor for bradykinin. The 9 aa bradykinin peptide elicits many responses including vasodilation, edema, smooth muscle spasm and pain fiber stimulation. Bradykinin is released upon activation by pathophysiologic conditions such as trauma and inflammation, and binds to its kinin receptors, B1 and B2. The B2 receptor associates with G proteins that stimulate a phosphatidylinositol-calcium second messenger system. [provided by RefSeq, Apr 2020]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.621C>A (p.N207K) alteration is located in exon 3 (coding exon 2) of the BDKRB2 gene. This alteration results from a C to A substitution at nucleotide position 621, causing the asparagine (N) at amino acid position 207 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
