Methods for genotyping selected polymorphism
First Claim
1. A method for amplifying a collection of target sequences from a nucleic acid sample wherein each target sequence comprises a common sequence and a consensus sequence immediately adjacent to the common sequence, the method comprising:
- fragmenting the nucleic acid sample into fragments with a selected restriction enzyme;
ligating an adaptor to the fragments to obtain adaptor-ligated fragments, wherein said adaptor comprises a first priming sequence;
contacting the adaptor-ligated fragments with probes, wherein each probe comprises a second priming sequence and a target specific sequence that comprises a region that is complementary to the common sequence and a region that is complementary to the consensus sequence;
extending at least some of the probes; and
amplifying the extended probes with primers to said first and second priming sequences.

Abstract
Methods for genotyping polymorphisms using a locus specific primer that is complementary to a region near a selected polymorphism are described. Methods for synthesizing pools of locus specific primers that incorporate some degenerate positions are also disclosed. A plurality of different sequence capture probes are synthesized simultaneously using degenerate oligonucleotide synthesis. The sequence of the locus specific regions of the capture probes are related in that they have some bases that are identical in each sequence in the plurality of sequences and positions that vary from one locus specific region to another. The sequences are selected based on proximity to a polymorphism of interest and because they conform to a similar sequence pattern.
