Genes affected

GRK7 (HGNC:17031): (G protein-coupled receptor kinase 7) This gene encodes a member of the guanine nucleotide-binding protein (G protein)-coupled receptor kinase subfamily of the Ser/Thr protein kinase family. It is specifically expressed in the retina and the encoded protein has been shown to phosphorylate cone opsins and initiate their deactivation. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 19, 2022

The c.517G>A (p.D173N) alteration is located in exon 1 (coding exon 1) of the GRK7 gene. This alteration results from a G to A substitution at nucleotide position 517, causing the aspartic acid (D) at amino acid position 173 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
