Leber congenital amaurosis 3

Autosomal recessive childhood-onset severe retinal dystrophy is a heterogeneous group of disorders affecting rod and cone photoreceptors simultaneously. The most severe cases are termed Leber congenital amaurosis, whereas the less aggressive forms are usually considered juvenile retinitis pigmentosa (Gu et al., 1997). Mackay et al. (2011) concluded that SPATA7 retinopathy is an infantile-onset severe cone-rod dystrophy with early extensive peripheral retinal atrophy but with variable foveal involvement. For a general phenotypic description and a discussion of genetic heterogeneity of Leber congenital amaurosis, see LCA1 (204000); for retinitis pigmentosa, see 268000.
