The most abundant 9-marker haplotype of the BAT1-NFKBIL1-LTA region, named haplotype 1 (28% frequency in the study population), included the alleles of the five protective genotypes and was related with a significantly lower risk of myocardial infarction (OR 0.88, 95% CI 0.80-0.98; P = 0.015).

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.
Subsequent linkage-disequilibrium (LD) mapping and analyses of haplotype structure showed significant associations between myocardial infarction and a single 50 kb halpotype comprised of five SNPs in LTA (encoding lymphotoxin-alpha), NFKBIL1 (encoding nuclear factor of kappa light polypeptide gene enhancer in B cells, inhibitor-like 1) and BAT1 (encoding HLA-B associated transcript 1).
