Summaries for OPN1LW Gene

Entrez Gene Summary for OPN1LW Gene

  • This gene encodes for a light absorbing visual pigment of the opsin gene family. The encoded protein is called red cone photopigment or long-wavelength sensitive opsin. Opsins are G-protein coupled receptors with seven transmembrane domains, an N-terminal extracellular domain, and a C-terminal cytoplasmic domain. This gene and the medium-wavelength opsin gene are tandemly arrayed on the X chromosome and frequent unequal recombination and gene conversion may occur between these sequences. X chromosomes may have fusions of the medium- and long-wavelength opsin genes or may have more than one copy of these genes. Defects in this gene are the cause of partial, protanopic colorblindness.

Disorders for OPN1LW Gene

(2) OMIM Diseases for OPN1LW Gene (300822)


  • Colorblindness, partial, protan series (CBP) [MIM:303900]: A color vision defect characterized by a dichromasy in which red and green are confused, with loss of luminance and shift of brightness and hue curves toward the short wave end of the spectrum. Dichromasy is due to the use of only two types of photoreceptors, blue plus red in deuteranopia and blue plus green in protanopia. {ECO:0000269 PubMed:12051694}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Blue cone monochromacy (BCM) [MIM:303700]: A rare X-linked congenital stationary cone dysfunction syndrome characterized by the absence of functional long wavelength-sensitive and medium wavelength-sensitive cones in the retina. Color discrimination is severely impaired from birth, and vision is derived from the remaining preserved blue (S) cones and rod photoreceptors. BCM typically presents with reduced visual acuity, pendular nystagmus, and photophobia. Patients often have myopia. {ECO:0000269 PubMed:8213841, ECO:0000269 PubMed:8666378}. Note=The disease is caused by mutations affecting the gene represented in this entry.
