Association of variants in the BAT1-NFKBIL1-LTA genomic region with protection against myocardial infarction in Europeans.

Single-nucleotide polymorphisms within the BAT1-NFKBIL1-LTA genomic region (6p21.3) and the LGALS2 gene (22q13.1), encoding a regulator for lymphotoxin-alpha, the product of the LTA gene, have been reported to be linked with the risk of myocardial infarction in Japanese.

TaqMan assays for genotyping of single nucleotide polymorphisms present at a disease susceptibility locus on chromosome 6.

Multiple single-nucleotide polymorphisms in the BAT1-NFKBIL1-LTA region on the short arm of chromosome 6 have been found to be associated with susceptibility to myocardial infarction in a recent case-control study including individuals from Japan. Specifically, the association relates to homozygosity for the minor alleles of five individual polymorphisms (one each in BAT1 and NFKBIL1 and three in LTA) and a haplotype defined by a particular allele combination of 10 polymorphisms (three each in BAT1 and NFKBIL1 and four in LTA). In the Japanese study, genotype determinations were carried out using a multiplex PCR-Invader assay or DNA sequencing.
