Use of 5-lipoxygenase activating protein (FLAP) gene to assess susceptibility for myocardial infarction
View Patent ↗Linkage of Myocardial Infarction (MI) to a locus on chromosome 13q12-13 is disclosed. In particular, the FLAP gene within this locus is shown by association analysis to be a susceptibility gene for MI and stroke. Pathway targeting for drug delivery and diagnosis applications in identifying those at risk of developing MI or stroke, in particular are described.
1. A method of assessing susceptibility to myocardial infarction (MI) in a human individual, the method comprising:
screening nucleic acid of the individual to determine whether the nucleic acid comprises a 5-lipoxygenase activating protein (FLAP) haplotype that comprises polymorphisms SG13S114, allele T; SG13S32, allele A; SG13S25, allele G; and SG13S89, allele G;
wherein the presence of the haplotype in the nucleic acid of the individual identifies the individual as having elevated susceptibility to MI, and wherein the absence of the haplotype in the nucleic acid of the individual identifies the individual as not having the elevated susceptibility to MI due to the haplotype.
2. The method of claim 1 , wherein the haplotype further comprises polymorphism SG13S99, allele T.
3. The method of claim 1 or 2 , comprising obtaining a biological sample from the individual that comprises the nucleic acid, and screening the nucleic acid from the biological sample.
4. The method of claim 1 or 2 , wherein the screening step comprises subjecting said nucleic acid to at least one procedure selected from the group consisting of: (a) enzymatic amplification of nucleic acid from the individual; (b) electrophoretic analysis; (c) restriction fragment length polymorphism analysis; and (d) nucleotide sequence analysis.
