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 05, 2024The c.77G>A (p.R26H) alteration is located in exon 2 (coding exon 2) of the GRK4 gene. This alteration results from a G to A substitution at nucleotide position 77, causing the arginine (R) at amino acid position 26 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
