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

May 21, 2024

The c.158C>G (p.S53C) alteration is located in exon 1 (coding exon 1) of the GRK7 gene. This alteration results from a C to G substitution at nucleotide position 158, causing the serine (S) at amino acid position 53 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
