Description : Retinitis pigmentosa is characterized by constriction of the visual fields, night
blindness, and fundus changes, including 'bone corpuscle' lumps of pigment. RP unassociated
with other abnormalities is inherited most frequently (84%) as an autosomal recessive,
next as an autosomal dominant (10%), and least frequently (6%) as an X-linked recessive
in the white U.S. population (Boughman et al., 1980). For a phenotypic description
and a discussion of genetic heterogeneity of retinitis pigmentosa, see 268000.;
Inheritance : X-linked;
Molecular basis : Caused by mutation in the RP2 gene (RP2, 312600.0001);
