Genes affected

OPN3 (HGNC:14007): (opsin 3) Opsins are members of the guanine nucleotide-binding protein (G protein)-coupled receptor superfamily. In addition to the visual opsins, mammals possess several photoreceptive non-visual opsins that are expressed in extraocular tissues. This gene, opsin 3, is strongly expressed in brain and testis and weakly expressed in liver, placenta, heart, lung, skeletal muscle, kidney, and pancreas. The gene may also be expressed in the retina. The protein has the canonical features of a photoreceptive opsin protein. [provided by RefSeq, Jul 2008]

Oct 24, 2024

The c.698G>A (p.R233H) alteration is located in exon 3 (coding exon 3) of the OPN3 gene. This alteration results from a G to A substitution at nucleotide position 698, causing the arginine (R) at amino acid position 233 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
