Association between the FABP2 Ala54Thr and CRP+1059C/G polymorphisms and small dense LDL level in patients with atherosclerosis: a case-control study.

BACKGROUND The polymorphisms of fatty acid-binding protein 2 (FABP2) and C-reactive protein (CRP) might act as genetic risk factors for atherosclerosis. The study aimed to investigate the relationship between FABP2 Ala54Thr and CRP+1059C/G polymorphisms and atherosclerosis as well as the association of Small dense-LDL (sd-LDL). METHODS A total of 255 subjects (125 controls and 130 patients) were included. The FABP2 and CRP polymorphisms were determined by PCR-RFLP and AS-PCR methods, respectively. Sd-LDL was measured based on Hirano et al method. RESULTS There were no significant distinctions between the patient and control groups concerning FABP2 and CRP polymorphisms (p > .05). No significant relationship was observed between studied polymorphisms and sd-LDL level in the patient group (p > .05). However, patients group had higher level of sd-LDL compared to controls (p < .05). CONCLUSION FABP2 Ala54Thr and CRP+1059G/C polymorphisms were not associated with atherosclerosis and sd-LDL level. However, the increased sd-LDL level was known as a risk factor for atherosclerosis.
