Genes affected

GRK4 (HGNC:4543): (G protein-coupled receptor kinase 4) This gene encodes a member of the guanine nucleotide-binding protein (G protein)-coupled receptor kinase subfamily of the Ser/Thr protein kinase family. The protein phosphorylates the activated forms of G protein-coupled receptors thus initiating its deactivation. This gene has been linked to both genetic and acquired hypertension. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2013]

The c.548C>G (p.T183R) alteration is located in exon 7 (coding exon 7) of the GRK4 gene. This alteration results from a C to G substitution at nucleotide position 548, causing the threonine (T) at amino acid position 183 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
