Autosomal-recessive microcephaly and chorioretinopathy (MCCRP) is a rare developmental disorder characterized by primary microcephaly, delayed psychomotor development, growth retardation with dwarfism, and visual impairment. In MCCRP, microcephaly ranges from mild to severe and has variable impact on cognitive performance, ranging from moderate developmental delay to normal intelligence. The features of the visual impairment in MCCRP patients are variable, but the chorioretinopathy is a constant feature and includes typical punched-out lesions that can severely impair vision and occasional retinal folds that can progress to retinal detachment. To date, three responsible genes have been described.
