Genes affected

RRH (HGNC:10450): (retinal pigment epithelium-derived rhodopsin homolog) Opsins are members of the guanine nucleotide-binding protein (G protein)-coupled receptor superfamily. This gene belongs to the seven-exon subfamily of mammalian opsin genes that includes opsin 5 and retinal G protein coupled receptor. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.539G>A (p.R180K) alteration is located in exon 4 (coding exon 4) of the RRH gene. This alteration results from a G to A substitution at nucleotide position 539, causing the arginine (R) at amino acid position 180 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
