2 . The method of claim 1 in which the altered risk is an increased risk.
3 . The method of claim 2 in which said individual has previously had an MI.
4 . The method of claim 1 in which the altered risk is a decreased risk.
5 . The method of claim 1 , wherein the SNP is selected from the group consisting of the SNPs set forth in Table 6.
6 .

7 . An isolated nucleic acid molecule comprising at least 8 contiguous nucleotides wherein one of the nucleotides is a single nucleotide polymorphism (SNP) selected from any one of the nucleotide sequences in SEQ ID NOS: 1-126 and 253-17,275, or a complement thereof.
8 . The isolated nucleic acid molecule of claim 7 , wherein the SNP is selected from the group consisting of the SNPs set forth in Tables 3 and 4.
9 . An isolated nucleic acid molecule that encodes any one of the amino acid sequences in SEQ ID NOS:127-252.
10 . An isolated polypeptide comprising an amino acid sequence selected from the group consisting of SEQ ID NOS:127-252.
11 . An antibody that specifically binds to a polypeptide of claim 10 , or an antigen-binding fragment thereof.
12 . The antibody of claim 11 in which the antibody is a monoclonal antibody.
13 . An amplified polynucleotide containing a single nucleotide polymorphism (SNP) selected from any one of the nucleotide sequences of SEQ ID NOS:1-126 and 253-17,275, or a complement thereof, wherein the amplified polynucleotide is between about 16 and about 1,000 nucleotides in length.
14 . The amplified polynucleotide of claim 13 in which the nucleotide sequence comprises any one of the nucleotide sequences of SEQ ID NOS: 1-1 26 and 253-=b 17 , 275 .
15 . An isolated polynucleotide which specifically hybridizes to a nucleic acid molecule containing a single nucleotide polymorphism (SNP) in any one of the nucleotide sequences in SEQ ID NOS:1-126 and 253-17,275.
16 . The polynucleotide of claim 15 that is 8-70 nucleotides in length.
17 . The polynucleotide of claim 15 that is an allele-specific probe.
18 . The polynucleotide of claim 15 that is an allele-specific primer.
19 . The polynucleotide of claim 15 , wherein the polynucleotide comprises a nucleotide sequence selected from the group consisting of the primer sequences set forth in Table 5 (SEQ ID NOS:17,276-17,377).
20 . A kit for detecting a single nucleotide polymorphism (SNP) in a nucleic acid, comprising the polynucleotide of claim 15 , a buffer, and an enzyme.
21 . A method of detecting a single nucleotide polymorphism (SNP) in a nucleic acid molecule, comprising contacting a test sample with a reagent which specifically hybridizes to a SNP in any one of the nucleotide sequences of SEQ ID NOS:1-126 and 253-17,275 under stringent hybridization conditions, and detecting the formation of a hybridized duplex.
22 . The method of claim 21 in which detection is carried out by a process selected from the group consisting of: allele-specific probe hybridization, allele-specific primer extension, allele-specific amplification, sequencing, 5′ nuclease digestion, molecular beacon assay, oligonucleotide ligation assay, size analysis, and single-stranded conformation polymorphism.
23 . A method of detecting a variant polypeptide, comprising contacting a reagent with a variant polypeptide encoded by a single nucleotide polymorphism (SNP) in any one of the nucleotide sequences of SEQ ID NOS:1-126 and 253-17,275 in a test sample, and detecting the binding of the reagent to the polypeptide.
24 . A method for identifying an agent useful in therapeutically or prophylactically treating MI, comprising contacting the polypeptide of claim 10 with a candidate agent under conditions suitable to allow formation of a binding complex between the polypeptide and the candidate agent, and detecting the formation of the binding complex, wherein the presence of the complex identifies said agent.
25 . A method for identifying an individual who is in need of receiving treatment for MI, comprising detecting a single nucleotide polymorphism (SNP) in a sample from that individual in any one of the genes listed in Table 6 and treating that individual with a therapeutic agent.
26 . The method of claim 25 , wherein the therapeutic agent is a statin.
