Fluorescence quantitative detecting method for CYP2C19 genotyping
The invention relates to a fluorescent quantitative detecting method for CYP2C19 genotyping fluorescent and a diagnostic kit. At present, CYP2C19 genotyping techniques at home and abroad are mainly RFLP technique and ALA technique which determine genotypes according to the size of a DNA fragment, with the disadvantages of time-consuming operation and low flux. The invention provides a novel point mutating or SNP detecting method which utilizes the ASA combination primer sequence designed for the polymorphic loci of the CYP2C19 gene exons 4 and 5, the referential ASA primer combination or the degenerated primer sequence for quality control, specific TaqMan-MGB probe sequences for amplified products, an ASA amplifying reaction method, the amplifying reaction result of real-time fluorescent quantitative detection, the fast analysis of mutation locus type and genotyping. The quantitative detecting method has the advantages of time saving compared with a conventional ASA method, no need for electrophoresis detection, fastness, accuracy, and the like, and can be used for detecting other drug-metabolizing enzymes, or more extensive genetic variation or mutation.

Method of identifying genomic rearrangements
InactiveUS6895337B1Quickly and accurately analyzedImprove accuracyComputer controlRead-only memoriesHeterologousHaplotype
Methods, computer program products and systems are provided for detecting large genomic rearrangements based on unphased genotype data obtained using common genotyping techniques that do not differentiate different alleles. In the method, unphased genotypes at a plurality of nucleotide variant markers of a particular gene in a diploid subject are compared with a canonical haplotype collection of the gene for a heterogeneous subject population. If the unphased genotypes cannot be reduced to a pair of canonical haplotypes within the canonical haplotype collection, it would indicate an increased likelihood that an allele of the gene in the diploid subject harbors a genomic rearrangement.
