Name OMIM Gene Description Ocular albinism, type 1 (OA1): 300500: GPR143: Also known as Nettleship–Falls syndrome, [4] [5] [6] is the most common variety of ocular albinism. OA1 is usually associated with nystagmus, and difficult to otherwise detect in females; males show more readily observable symptoms.
Retinitis pigmentosa (RP) is a member of a group of genetic disorders called inherited retinal dystrophy (IRD) that cause loss of vision. [1] Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). [1]
The brain and eyes, for example, can be significantly impacted by mutations in this gene and cause disorders such as Microphthalmia and Holoprosencephaly. [39] Microphthalmia is a condition that affects the eyes, which results in small, underdeveloped tissues in one or both eyes. [ 39 ]
Leber's hereditary optic neuropathy (LHON) is a mitochondrially inherited (transmitted from mother to offspring) degeneration of retinal ganglion cells (RGCs) and their axons that leads to an acute or subacute loss of central vision; it predominantly affects adult males, and onset is more likely in younger adults.
Fruitflies lacking the PAX6 gene have no eyes. PAX6 is a member of the Pax gene family which is responsible for carrying the genetic information that will encode the Pax-6 protein. It acts as a "master control" gene for the development of eyes and other sensory organs, certain neural and epidermal tissues as well as other homologous structures ...
Gene therapy is designed to insert a copy of a corrected gene into retinal cells. The hope is to return cell function back to normal and the treatment has the potential to stop disease progression. This therapy will not restore impaired vision back to normal. The research is being undertaken by a partnership between Sanofi and Oxford BioMedica.

OCA2 encodes the human homologue of the mouse p (pink-eyed dilution) gene. In human, the OCA2 gene is located on the long (q) arm of chromosome 15 between positions 12 and 13.1. The human OCA2 gene is located on the long arm (q) of chromosome 15, specifically from base pair 28,000,020 to base pair 28,344,457 on chromosome 15.
