Genes affected

GRK3 (HGNC:290): (G protein-coupled receptor kinase 3) The beta-adrenergic receptor kinase specifically phosphorylates the agonist-occupied form of the beta-adrenergic and related G protein-coupled receptors. Overall, the beta adrenergic receptor kinase 2 has 85% amino acid similarity with beta adrenergic receptor kinase 1, with the protein kinase catalytic domain having 95% similarity. These data suggest the existence of a family of receptor kinases which may serve broadly to regulate receptor function. [provided by RefSeq, Jul 2008]

Ambry Genetics

Aug 13, 2021

The c.883C>T (p.R295W) alteration is located in exon 11 (coding exon 11) of the GRK3 gene. This alteration results from a C to T substitution at nucleotide position 883, causing the arginine (R) at amino acid position 295 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
