Comparing strategies to fine-map the association of common SNPs at chromosome 9p21 with type 2 diabetes and myocardial infarction
Noncoding variants at human chromosome 9p21 near CDKN2A and CDKN2B are associated with type 2 diabetes(1-4), myocardial infarction(5-7), aneurysm(8), vertical cup disc ratio(9) and at least five cancers(10-16). Here we compare approaches to more comprehensively assess genetic variation in the region. We carried out targeted sequencing at high coverage in 47 individuals and compared the results to
