Comparing the GWAS meta-analysis of all MI cases to MI-free controls, we find that all four regions that were identified as common for single and recurrent MI (regions in or close to the genes HPCAL1, LPA, CDKN2A, and CXADR) were also found in the full MI GWAS meta-analysis. Here, CDKN2A is linked to myocardial infarction.
