Genes affected

OPN1SW (HGNC:1012): (opsin 1, short wave sensitive) This gene belongs to the G-protein coupled receptor 1 family, opsin subfamily. It encodes the blue cone pigment gene which is one of three types of cone photoreceptors responsible for normal color vision. Defects in this gene are the cause of tritan color blindness (tritanopia). Affected individuals lack blue and yellow sensory mechanisms while retaining those for red and green. Defective blue vision is characteristic. [provided by RefSeq, Jul 2008]

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 264 of the OPN1SW protein (p.Pro264Ser). This variant is present in population databases (rs104894033, gnomAD 0.005%). This missense change has been observed in individuals with retinitis pigementosa and/or tritanopia (PMID: 1386496, 31816670). ClinVar contains an entry for this variant (Variation ID: 64). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
