Linkage of internal minisatellite loci on chromosome 1 and exclusion of autosomal dominant retinitis pigmentosa proximal to rhesus.

We report the exclusion of a locus for autosomal dominant retinitis pigmentosa proximal to the rhesus locus in a single large pedigree. In addition, a previously unreported linkage is described between two chromosome 1 markers, which confirms that a highly variable minisatellite locus is placed internally on chromosome 1.
