Abstract: bjective: Hepatic lipase (HL) is involved in the metabolism of several lipoproteins and has a key role in reverse cholesterol transport and atherosclerosis. The aim of this study was to evaluate the effects of HL -514C/T polymorphism on sub-clinical and established carotid atherosclerotic in hyperalphalipoproteinemic and control individuals. Methods: One hundred and sixty nine asymptomatic individuals (aged 47 ± 16 years), 71 hyperalphalipoproteinemic (Hyper-A, HDL-C ? 68mg/dL) and 98 controls (CTL, HDL-C 68mg/dL) were selected by clinical and laboratory evaluations. Lipids and lipoproteins were measured by enzymatic methods. HL activity was measured in post-heparin plasma by a radiometric assay and HL-514C/T genotypes were analyzed by PCR. Carotid intima-media thickness (cIMT) was measured by Doppler ultrasonography. Results: No differences in HL -514C/T genotype frequencies were observed between the groups. HL -514C/T polymorphism did not contribute to variations in cIMT or atherosclerotic lesion frequencies in Hyper-A and controls. Furthermore, no interactions between HL-514C/T polymorphism and cIMT or atherosclerotic lesions were found.Conclusions: In hyperalphalipoproteinemic individuals the -514C/T polymorphism is not associated with significant variations in HDL-Cholesterol concentrations. Besides, it has no repercussions on carotid atherosclerosis, although hepatic lipase activity is significantly reduced. © 2013 por la Sociedad Argentina de Endocrinologia y Metabolismo.
