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]

The c.920C>A (p.A307D) alteration is located in exon 7 (coding exon 7) of the RRH gene. This alteration results from a C to A substitution at nucleotide position 920, causing the alanine (A) at amino acid position 307 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
