RESUMEN
<p><b>OBJECTIVE</b>To analyze the effects of cholesterol ester transfer protein (CETP) Taq1B polymorphism on the response of serum HDL-C to dietary factors in hyperlipidemia patients.</p><p><b>METHODS</b>All 141 hyperlipidemia residents in a community in Shanghai were investigated by a 3-day diet questionnaire. The serum lipids were analyzed, and the polymorphism of CETP gene was detected by PCR-RFLP method. The correlation between dietary factors and serum HDL-C in different genotype was analyzed when considering the effects of sex, age and body mass index.</p><p><b>RESULT</b>The HDL-C of hyperlipidemia patients was affected by dietary factors and CETP gene Taq1B polymorphism. The strength of the correlation between dietary factors and serum HDL-C was different among the genotype groups. The relation was shown closer in B(2)B(2) subjects than in B(1)B(1).</p><p><b>CONCLUSION</b>The Taq1B CETP gene polymorphism should be a strong determinant of HDL-C in hyperlipidemia patients, and might contribute to the heterogeneity in HDL-C response to dietary intervention.</p>
