Abstract excerpt
PURPOSE: To describe a hierarchical approach for efficient genetic diagnosis of autosomal dominant retinitis pigmentosa (adRP). METHODS: Forty di-, tri-, or tetra-nucleotide repeats tightly linked to 10 genes known to be responsible for adRP were identified from the human genome sequence and used as markers in multiplex amplification and genotyping, followed by linkage analysis. Discordance of cosegregation of...
