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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.765A>C (p.E255D) alteration is located in exon 9 (coding exon 9) of the GRK4 gene. This alteration results from a A to C substitution at nucleotide position 765, causing the glutamic acid (E) at amino acid position 255 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
