title: PITPNM3 is an uncommon cause of cone and cone-rod dystrophies.
abstract: The first mutation in PITPNM3, a human homologue of the Drosophila retinal degeneration (rdgB not not) gene was reported in two large Swedish families with autosomal dominant cone dystrophy. To establish the global impact that PITPNM3 has on retinal degenerations we screened 163 patients from Denmark, Germany, the UK, and USA. Four sequence variants, two missence mutations and two intronic changes were identified in the screen. Thus, mutations in PITPNM3 do not appear to be a major cause of cone or cone-rod dystrophy.
