title: Gene of type II autosomal dominant retinitis pigmentosa maps on the long arm of chromosome 3.
abstract: Linkage analysis has been performed on a large Australian family segregating for the autosomal dominant form of retinitis pigmentosa (ADRP). The majority of patients had no subjective symptoms of night blindness until their second decade and good visual acuity until late in life. The disease in this family has been classified as Type II ADRP according to the subdivisions provided by both Massof and Finkelstein and Fishman and colleagues. Linkage (Omax:0.08 at Zmax:4.78) is here demonstrated between the disease locus and D3S47 (a marker locus on the long arm of chromosome 3), which showed in an earlier study very close linkage without recombination to the disease locus in an Irish pedigree with a clinically more severe and early onset (Type I) ADRP.
