Choroideremia
Choroideremia (CHM) is characterized by progressive chorioretinal degeneration in affected males and milder signs in heterozygous (carrier) females. Typically, symptoms in affected males evolve from night blindness to peripheral visual field loss, with central vision preserved until late in life. Although carrier females are generally asymptomatic, signs of chorioretinal degeneration can be reliably observed with fundus autofluorescence imaging, and – after age 25 years – with careful fundus examination.

Retinitis pigmentosa 2
Retinitis pigmentosa is characterized by constriction of the visual fields, night blindness, and fundus changes, including 'bone corpuscle' lumps of pigment. RP unassociated with other abnormalities is inherited most frequently (84%) as an autosomal recessive, next as an autosomal dominant (10%), and least frequently (6%) as an X-linked recessive in the white U.S. population (Boughman et al., 1980). For a general phenotypic description and a discussion of genetic heterogeneity of retinitis pigmentosa, see 268000. [from OMIM]
Stickler syndrome, type 4
Stickler syndrome is a connective tissue disorder that can include ocular findings of myopia, cataract, and retinal detachment; hearing loss that is both conductive and sensorineural; midfacial underdevelopment and cleft palate (either alone or as part of the Robin sequence); and mild spondyloepiphyseal dysplasia and/or precocious arthritis. Variable phenotypic expression of Stickler syndrome occurs both within and among families; interfamilial variability is in part explained by locus and allelic heterogeneity. [from GeneReviews]
Late-onset retinal degeneration
Late-onset retinal degeneration (LORD) is an autosomal dominant disorder characterized by onset in the fifth to sixth decade with night blindness and punctate yellow-white deposits in the retinal fundus, progressing to severe central and peripheral degeneration, with choroidal neovascularization and chorioretinal atrophy (Hayward et al., 2003). [from OMIM]
Microcornea-myopic chorioretinal atrophy
Microcornea-myopic chorioretinal atrophy-telecanthus syndrome is rare, genetic, developmental defect of the eye disease characterized by childhood onset of mild to severe myopia with microcornea and chorioretinal atrophy, typically associated with telecanthus and posteriorly rotated ears. Other variable features include early-onset cataracts, ectopia lentis, ecotpia pupilae and retinal detachment. [from ORDO]
Choroideremia-deafness-obesity syndrome
An X-linked retinal dystrophy characterized by choroideremia, causing in affected males progressive nyctalopia and eventual central blindness. Obesity, moderate intellectual disability and congenital mixed (sensorineural and conductive) deafness are also observed. Female carriers show typical retinal changes indicative of the choroideremia carrier state. [from ORDO]
Intellectual disability, autosomal dominant 33
Any autosomal dominant non-syndromic intellectual disability in which the cause of the disease is a mutation in the DPP6 gene. [from MONDO]
Ophthalmoplegia, external, and myopia
Retinitis pigmentosa 6
A retinitis pigmentosa that has material basis in variation in the chromosome region Xp21.3-p21.2. [from MONDO]
