The present invention provides oligonucleotides and methods for amplifying detecting and, identifying sequence variations associated with hemochromatosis. It has been found that the reduced, efficiency of primer extension by DNA polymerases when the 3' end of a primer does not hybridize, perfectly with the target can be adapted for use as a means for distinguishing or identifying the, nucleotide in the target which is at the site where the diagnostic mismatch between the detector, primer and the target occurs. The efficiency of detector primer extension is detected as an indication, of the presence and/or identity of the sequence variation in the target. The inventive methods make, …

Why it's free to use
- Filed April 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 14, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 14, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
