Genetic polymorphisms associated with cardiovascular diseases, methods of detection and uses thereof
View Patent ↗The present invention provides compositions and methods based on genetic polymorphisms that are associated with cardiovascular diseases, particularly coronary heart disease (especially myocardial infarction) or hypertension. For example, the present invention relates to nucleic acid molecules containing the polymorphisms, variant proteins encoded by these nucleic acid molecules, reagents for detecting the polymorphic nucleic acid molecules and variant proteins, and methods of using the nucleic acid molecules and proteins as well as methods of using reagents for their detection.
1. A method for determining that a human has an increased risk for myocardial infarction (MI), comprising testing nucleic acid from said human to determine the nucleotide content at polymorphism rs3739998 as represented by position 101 of SEQ ID NO:2024 or its complement, wherein the presence of G at position 101 of SEQ ID NO:2024 or C at position 101 of its complement is detected and indicates that said human has said increased risk for MI.
2. The method of claim 1 , wherein said nucleic acid is a nucleic acid extract from a biological sample from said human.
3. The method of claim 2 , wherein said biological sample is blood, saliva, or buccal cells.
4. The method of claim 2 , further comprising preparing said nucleic acid extract from said biological sample prior to said testing.
5. The method of claim 4 , further comprising obtaining said biological sample from said human prior to said preparing.
6. The method of claim 1 , wherein said testing comprises nucleic acid amplification.
7. The method of claim 6 , wherein said nucleic acid amplification is carried out by polymerase chain reaction.
8. The method of claim 1 , wherein said correlating is performed by computer software.
9. The method of claim 1 , wherein said testing is performed using sequencing, 5′ nuclease digestion, molecular beacon assay, oligonucleotide ligation assay, size analysis, single-stranded conformation polymorphism analysis, or denaturing gradient gel electrophoresis (DGGE).
10. The method of claim 1 , wherein said testing is performed using an allele-specific method.
11. The method of claim 10 , wherein said allele-specific method is allele-specific probe hybridization, allele-specific primer extension, or allele-specific amplification.
12. The method of claim 10 , wherein said testing is carried out using an allele-specific primer that comprises a sequence selected from the group consisting of SEQ ID NOS:4382-4383 and sequences fully complementary thereto.
13. The method of claim 1 which is an automated method.
14. The method of claim 1 , wherein said human is homozygous for said G or said C.
15. The method of claim 1 , wherein said human is heterozygous for said G or said C.
16. A method for determining that a human has an increased risk for myocardial infarction (MI), comprising:
a) testing nucleic acid from said human to determine the nucleotide content at polymorphism rs3739998 as represented by position 101 of SEQ ID NO:2024 or its complement; and
b) correlating the presence of G at position 101 of SEQ ID NO:2024 or C at position 101 of its complement with said human having said increased risk for MI or correlating the absence of said G or said C with said human not having said increased risk for MI.
17. The method of claim 16 , wherein said correlating is performed by computer software.
18. The method of claim 16 , wherein said nucleic acid is a nucleic acid extract from a biological sample from said human.
19. The method of claim 18 , wherein said biological sample is blood, saliva, or buccal cells.
20. The method of claim 18 , further comprising preparing said nucleic acid extract from said biological sample prior to said testing.
21. The method of claim 20 , further comprising obtaining said biological sample from said human prior to said preparing.
22. The method of claim 16 , wherein said testing comprises nucleic acid amplification.
23. The method of claim 22 , wherein said nucleic acid amplification is carried out by polymerase chain reaction.
24. The method of claim 16 , wherein said testing is performed using sequencing, 5′ nuclease digestion, molecular beacon assay, oligonucleotide ligation assay, size analysis, single-stranded conformation polymorphism analysis, or denaturing gradient gel electrophoresis (DGGE).
25. The method of claim 16 , wherein said testing is performed using an allele-specific method.
26. The method of claim 25 , wherein said allele-specific method is allele-specific probe hybridization, allele-specific primer extension, or allele-specific amplification.
27. The method of claim 25 , wherein said testing is carried out using an allele-specific primer that comprises a sequence selected from the group consisting of SEQ ID NOS:4382-4383 and sequences fully complementary thereto.
28. The method of claim 16 which is an automated method.
29. The method of claim 16 , wherein said human is homozygous for said G or said C.
30. The method of claim 16 , wherein said human is heterozygous for said G or said C.
