Summaries for Cone-Rod Dystrophy, X-Linked, 1

UniProtKB/Swiss-Prot : 72 Cone-rod dystrophy, X-linked 1: 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.

MalaCards based summary : Cone-Rod Dystrophy, X-Linked, 1, also known as cordx1, is related to retinal disease and cone dystrophy. An important gene associated with Cone-Rod Dystrophy, X-Linked, 1 is RPGR (Retinitis Pigmentosa GTPase Regulator), and among its related pathways/superpathways are Vesicle-mediated transport and Transport to the Golgi and subsequent modification. Affiliated tissues include eye, and related phenotypes are nystagmus and photophobia

Disease Ontology : 12 A cone-rod dystrophy that has material basis in mutation in an alternative terminal exon 15 of the RPGR gene on chromosome Xp11.

OMIM® : 57 X-linked cone-rod dystrophy is a rare, progressive visual disorder primarily affecting cone photoreceptors (Demirci et al., 2002). 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. The degree of rod photoreceptor involvement is variable, with increasing degeneration. Although penetrance appears to be nearly 100%, there is variable expressivity with respect to age at onset, severity of symptoms, and findings (Hong et al., 1994). (304020) (Updated 20-May-2021)
