Involvement in diseasei

Colorblindness, partial, deutan series (CBD)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA color vision defect characterized by a dichromasy in which red and green are confused, without loss of luminance or shift or shortening 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.

Blue cone monochromacy (BCM)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA 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.

Cone dystrophy 5 (COD5)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA X-linked cone dystrophy. Cone dystrophies are retinal dystrophies characterized by progressive degeneration of the cone photoreceptors with preservation of rod function, as indicated by electroretinogram. However, some rod involvement may be present in some cone dystrophies, particularly at late stage. Affected individuals suffer from photophobia, loss of visual acuity, color vision and central visual field. Another sign is the absence of macular lesions for many years. Cone dystrophies are distinguished from the cone-rod dystrophies in which some loss of peripheral vision also occurs.

Caution

Medium-wave-sensitive opsin genes vary in number among individuals and, together with a single red pigment gene, reside in a head-to-tail tandem array within the X chromosome. In the GRCh38 reference genome assembly, there are 3 genes in tandem coding for identical proteins AC P04001, AC P0DN77 and P0DN78.Curated
