Cone-rod Dystrophy, X-linked, 1; Cordx1

Description

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). Genetic Heterogeneity of X-linked Cone-Rod DystrophyAdditional forms of X-linked cone-rod dystrophy include CORDX2 (OMIM ), mapped to chromosome Xq27, and CORDX3 (OMIM ), caused by mutation in the CACNA1F gene (OMIM ) on chromosome Xp11.23.For a discussion of autosomal forms of cone-rod dystrophy, see CORD2 (OMIM ).
