Core Tip
Core Tip: This study identifies a novel synergistic cardiometabolic protective pathway in the genetically distinct Teochew (Chaozhou) Han population of southern China. We demonstrate that the co-presence of the apolipoprotein E (APOE) ε2 allele and high copy number variation of the lipoprotein(a) kringle IV type 2 gene significantly reduces coronary heart disease risk, contrasting with previous reports on APOE ε2 in Asians. This unique gene-environment interaction, potentially modulated by the local seafood-rich diet, offers a population-specific biomarker for optimized coronary heart disease risk stratification. Clinical translation emphasizes integrating APOE/lipoprotein(a) kringle IV type 2 copy number variation screening with solute carrier organic anion transporter family member 1B1 pharmacogenetics to guide precision statin therapy and personalized prevention strategies.
