  • Publication number: 20030054339
    Abstract: The present invention relates to a method for the rapid, reliable and precise detection of drug-induced mutations in the reverse transcriptase gene allowing the simultaneous characterization of a range of codons involved in drug resistance using specific sets of probes optimized to function together in a reverse-hybridization assay. More particularly, the present invention relates to the genetic detection of the following mutations in the HIV RT gene: K103N/R, V106A/I/L, Q151M/L, Y181C/I, M184V/I, Y188L, G190A/S/R and/or T215Y/F/D/S/A. The present invention also relates to probes and primers for such detection, to a diagnostic kit and a LiPA assay. The present invention further relates to HIV RT sequences comprising previously unknown polymorphisms.

  • Patent number: 6495670
    Abstract: The invention relates to a process for genotyping any HCV isolate present in a biological sample, previously identified as being HCV positive, and for classifying said isolate according to the percentage of homology with other HCV isolates, comprising the steps of: contacting said sample in which the ribonucleotides or deoxyribonucleotides have been made accessible, if need be, under suitable denaturation, with at least one probe from about 10 to about 40 nucleotides, with said probe being liable to hybridize to a region being in the domain extending from nucleotide at position −291 to nucleotide at position −66 of the 5′ untranslated region of one of the HCV isolates represented by their cDNA sequences, with said numbering of position beginning with the first ATG codon of the open reading frame encoding the HCV polyprotein, or with said probe being complementary to the above-defined probes, detecting the complexes possibly formed between said probe and the nucleotide sequence of the HCV i

  • Publication number: 20020183508
    Abstract: The present invention relates to new genomic nucleotide sequences and amino acid sequences corresponding to the coding region of these genomes. The invention relates to new HCV types and subtypes sequences which are different from the known HCV types and subtypes. More particularly, the present invention relates to new HCV type 7 sequences, new HCV type 9 sequences, new HCV type 10 and new HCV type 11 sequences. Also, the present invention relates to new HCV type 1 sequences of subtypes 1d, 1e, 1f and 1g; new HCV type 2 sequences of subtypes 2e, 2f, 2g, 2h, 2I, 2k and 2l; new HCV type 3 sequences of subtype 3g, new HCV type 4 sequences of subtypes 4k, 4l and 4m; a process for preparing them, and their use for diagnosis, prophylaxis and therapy. More particularly, the present invention provides new type-specific sequences of the Core, the E1 and the NS5 regions of new HCV types 7, 9, 10 and 11, as well as of new variants (subtypes) of HCV types 1, 2, 3 and 4.
