Genes affected

WDR64 (HGNC:26570): (WD repeat domain 64)

WDR64 links:

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]

The c.223C>G (p.R75G) alteration is located in exon 2 (coding exon 2) of the WDR64 gene. This alteration results from a C to G substitution at nucleotide position 223, causing the arginine (R) at amino acid position 75 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
