ABSTRACT
Rapid and accurate detection of genetic mutations based on nanotechnology would provide substantial advances in detection of polycystic kidney disease (PKD), a disease whose current methods of detection are cumbersome due to the large size and duplication of the mutated gene. In this study, a nanotechnology-based DNA assay was developed for detection of SNPs (single nucleotide polymorphisms) in a feline autosomal dominant PKD (ADPKD) model which can readily be adapted to diagnosis of human ADPKD type 1. Europium and terbium phosphors were doped into gadolinium crystal hosts with a magnetic core, providing stable luminescence and the possibility of magnetic manipulations in a solution-based assay. A hybridization-in-solution DNA assay was optimized for feline PKD gene SNP detection using genomic DNA extracted from feline kidney tissue and blood. This assay showed a substantial differentiation between PKD and control specimens. The nanotechnology-based DNA assay is attractive from the viewpoint of rapid availability, simple methodology, and cost reduction for clinical use to detect mutations involved in human ADPKD and other genetic diseases.

    Several previous reports have suggested that autosomal recessive polycystic kidney disease (ARPKD) is caused by mutations in a single gene (the PKDH1 gene). Linkage analysis showed a positive linkage for polymorphic markers at the short arm of chromosome 6 (6p) in all families. PKHD1 has not...

    Background: Oculopharyngeal muscular dystrophy (OPMD) is a late onset hereditary myopathy of autosomal dominant transmission characterised by ptosis, dysphagia and limb weakness. The disease is caused by short heterozygous expansions of a (GCN)10 triplet located in the first exon of the PABPN1...

    The long arm of the human Y chromosome is flecked with various fractions of repetitive DNA. DYZ1 is one such fraction, which is organized tandemly as an array of a 3.4-kb repeat ranging from 2000�4000 copies in normal males. We have studied the organizational variation of the DYZ1 fraction...

    Motivation: The complexity of a large number of recently discovered copy number polymorphisms is much higher than initially thought, thus making it more difficult to detect them in the presence of significant measurement noise. In this scenario, separate normalization and segmentation is prone...

    Background and Aims Ribosomal sequences have become the classical example of the genomic homogenization of nuclear multigene families. Despite theoretical advantages and modelling predictions that support concerted evolution of the 45S rDNA, several reports have found intragenomic polymorphisms....

This polymorphism was discovered because of a difference in the position of the centromere and because it occurs at varying frequencies in domesticated colonies in the USA and Germany and among two zebra finch subspecies....
