Core Tip
Core Tip: In this study of 324 patients with coronary heart disease (CHD) and 143 control participants, we analysed polymorphisms in the APOE and SLCO1B1 genes, as well as LPA KIV-2 copy number variation in the Teochew population of southern China. We confirmed that both APOE ε2 allele and higher KIV-2 copy number are associated with a reduced risk of CHD in the Teochew population, whereas neither the APOE ε4 allele nor SLCO1B1 gene showed any association.
