Abstract:
BACKGROUND: CETP(Cholesteryl ester transfer Protein) is the essential protein for 'reverse cholesterol transport' which transfers cholesteryl ester from HDL particles to other lipoproteins. The subjects with CETP deficiency caused by genetic mutation in the CETP gene have very high HDL levels that CETP deficiency implies anti-atherogenic effect. A missense mutation in the exon 15(D442G) and a splicing defect in the intron 14(Int 14A) in the CETP gene are reported to be popular among Japanese population which overall prevalence of both mutations is up to 10%. METHODS: To identify the CETP mutaion such as D442G or Int 14A among Koreans, seven subjects who have high HDL level above 80mg/dl and 14 first-degree relatives of them were included in this study. RESULTS: Of 21 subjects in 7 familes, 5 subjects in 2 families were confirmed as D442G mutation of CETP gene, but Int 14A mutation is not found. Subjects with D442G mutation have high apo A-I levels as well as HDL levels. CONCLUSION: The D442G mutation of CETP gene is firstly confirmed in Koreans. The CETP deficiency caused by genetic mutation in the CETP gene seems to be prevalent among Korean population.
