Expressed in the developing eye and brain. Expression in the retina peaks at fetal days 51-60. At 6-week old, in the retina, is predominantly detected in the neural layer (at protein level). At 8- and 10-week old, in the retina, the expression is strongest in the inner and middle layer of the neural part (at protein level).
PAX6 is a transcription factor with important roles in the development of the eye, nose, central nervous system, and pancreas. It competes with PAX4 for binding to a common element in the promoters of glucagon, insulin, and somatostatin.

Aniridia 1
AN1
A congenital, bilateral, panocular disorder characterized by complete absence of the iris or extreme iris hypoplasia. Aniridia is not just an isolated defect in iris development but it is associated with macular and optic nerve hypoplasia, cataract, corneal changes, nystagmus. Visual acuity is generally low but is unrelated to the degree of iris hypoplasia. Glaucoma is a secondary problem causing additional visual loss over time.
None
The disease is caused by variants affecting the gene represented in this entry.
Anterior segment dysgenesis 5
ASGD5
A form of anterior segment dysgenesis, a group of defects affecting anterior structures of the eye including cornea, iris, lens, trabecular meshwork, and Schlemm canal. Anterior segment dysgeneses result from abnormal migration or differentiation of the neural crest derived mesenchymal cells that give rise to components of the anterior chamber during eye development. Different anterior segment anomalies may exist alone or in combination, including iris hypoplasia, enlarged or reduced corneal diameter, corneal vascularization and opacity, posterior embryotoxon, corectopia, polycoria, abnormal iridocorneal angle, ectopia lentis, and anterior synechiae between the iris and posterior corneal surface. Clinical conditions falling within the phenotypic spectrum of anterior segment dysgeneses include aniridia, Axenfeld anomaly, Reiger anomaly/syndrome, Peters anomaly, and iridogoniodysgenesis.
None
The disease is caused by variants affecting the gene represented in this entry.
Foveal hypoplasia 1
FVH1
An isolated form of foveal hypoplasia, a developmental defect of the eye defined as the lack of foveal depression with continuity of all neurosensory retinal layers in the presumed foveal area. Clinical features include absence of foveal pit on optical coherence tomography, absence of foveal hyperpigmentation, absence of foveal avascularity, absence of foveal and macular reflexes, decreased visual acuity, and nystagmus. Anterior segment anomalies and cataract are observed in some FVH1 patients.
None
The disease is caused by variants affecting the gene represented in this entry.
Keratitis hereditary
KERH
An ocular disorder characterized by corneal opacification, recurrent stromal keratitis and vascularization.
None
The disease is caused by variants affecting the gene represented in this entry.
Microphthalmia/coloboma 12
MCOPCB12
A form of colobomatous microphthalmia, a disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues. Ocular abnormalities like coloboma, opacities of the cornea and lens, scaring of the retina and choroid, and other abnormalities may also be present. Ocular colobomas are a set of malformations resulting from abnormal morphogenesis of the optic cup and stalk, and the fusion of the fetal fissure (optic fissure). MCOPCB12 is an autosomal dominant form characterized by inter- and intrafamilial variability. Some patients also exhibit neurodevelopmental anomalies.
None
The disease is caused by variants affecting the gene represented in this entry.
Coloboma of optic nerve
COLON
An ocular defect that is due to malclosure of the fetal intraocular fissure affecting the optic nerve head. In some affected individuals, it appears as enlargement of the physiologic cup with severely affected eyes showing huge cavities at the site of the disk.
None
The disease is caused by variants affecting the gene represented in this entry.
Bilateral optic nerve hypoplasia
BONH
A congenital anomaly in which the optic disk appears abnormally small. It may be an isolated finding or part of a spectrum of anatomic and functional abnormalities that includes partial or complete agenesis of the septum pellucidum, other midline brain defects, cerebral anomalies, pituitary dysfunction, and structural abnormalities of the pituitary.
None
The disease is caused by variants affecting the gene represented in this entry.
Aniridia 2
AN2
A form of aniridia, a congenital, bilateral, panocular disorder characterized by complete absence of the iris or extreme iris hypoplasia. Aniridia is not just an isolated defect in iris development but it is associated with macular and optic nerve hypoplasia, cataract, corneal changes, nystagmus. Visual acuity is generally low but is unrelated to the degree of iris hypoplasia. Glaucoma is a secondary problem causing additional visual loss over time.
None
The gene represented in this entry is involved in disease pathogenesis. A mutation in a PAX6 long-range cis-regulatory element, known as SIMO, affects PAX6 expression in the developing eye and has pathological consequences. The mutation is located in ELP4 intron 9, 150 kb downstream of PAX6.
Ubiquitinated by TRIM11, leading to ubiquitination and proteasomal degradation.
Belongs to the paired homeobox family.
Isoform 1
Expressed in lymphoblasts.
Isoform 5a
Weakly expressed in lymphoblasts.
AN2, PAX6, Paired box protein Pax-6, Aniridia type II protein, Oculorhombin
