Genes affected

GRK1 (HGNC:10013): (G protein-coupled receptor kinase 1) 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 rhodopsin and initiates its deactivation. Defects in GRK1 are known to cause Oguchi disease 2 (also known as stationary night blindness Oguchi type-2).

The c.151C>T (p.R51C) alteration is located in exon 1 (coding exon 1) of the GRK1 gene. This alteration results from a C to T substitution at nucleotide position 151, causing the arginine (R) at amino acid position 51 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
