Description : 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 (summary by Gu et al., 1997). Mutation
in TULP1 can also cause a form of autosomal recessive retinitis pigmentosa (RP14;
600132). For a general phenotypic description and a discussion of the genetic heterogeneity
of Leber congenital amaurosis, see LCA1 (204000); for retinitis pigmentosa, see 268000.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the tubby-like protein 1 gene (TULP1, 602280.0004);
