Uniprot Description An inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa. In cone-rod dystrophy X-linked type 1 the degree of rod-photoreceptor involvement can be variable, with degeneration increasing as the disease progresses. Affected individuals (essentially all of whom are males) present with decreased visual acuity, myopia, photophobia, abnormal color vision, full peripheral visual fields, decreased photopic electroretinographic responses, and granularity of the macular retinal pigment epithelium. Although penetrance appears to be nearly 100%, there is variable expressivity with respect to age at onset and severity of symptoms.
Disease Ontology Description A cone-rod dystrophy that has_material_basis_in mutation in an alternative terminal exon 15 of the RPGR gene on chromosome Xp11.
