Genes affected

BDKRB1 (HGNC:1029): (bradykinin receptor B1) Bradykinin, a 9 aa peptide, is generated in pathophysiologic conditions such as inflammation, trauma, burns, shock, and allergy. The protein encoded by this gene belongs to the G-protein coupled receptor 1 family. Two types of G-protein coupled receptors have been found which bind bradykinin and mediate responses to these pathophysiologic conditions. The protein encoded by this gene is one of these receptors and is synthesized de novo following tissue injury. Receptor binding leads to an increase in the cytosolic calcium ion concentration, ultimately resulting in chronic and acute inflammatory responses. [provided by RefSeq, Aug 2020]

The c.437G>A (p.R146Q) alteration is located in exon 3 (coding exon 1) of the BDKRB1 gene. This alteration results from a G to A substitution at nucleotide position 437, causing the arginine (R) at amino acid position 146 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
