| Popis: | Background: Non-alcoholic fatty liver disease (NAFLD) as a severe health problem is the leading cause of morbidity and mortality from the chronic liver disease worldwide. NAFLD is tightly associated with dyslipidemia although the etiology is still unclear. ATP binding cassette subfamily A member 1 (ABCA1) is involved in cholesterol efflux, fatty acid oxidation, and inflammation. Although some reports show that the ABCA1 polymorphisms affect the lipids metabolism and severity of clinical liver diseases, the effects of ABCA1 polymorphisms on the development of NAFLD are unknown. Objectives: The current study was performed to investigate the association between the ABCA1 polymorphisms and the development of NAFLD and the effect of the four ABCA1 SNPs on the serum lipid levels. Methods: The ABCA1 polymorphisms (rs1800977, rs2066714, rs2066715, and rs2230808) were determined in 265 NAFLD patients and 126 healthy controls using the sequencing and polymerase chain reaction analysis. Serum lipid profiles and liver enzymes were examined using standard clinical laboratory methods. Results: There was a significant difference (P < 0.05) in the genotype of the ABCA1 rs1800977 G/A polymorphisms between NAFLD patients and healthy controls. No significant differences were found in genotypes and allele frequencies of the ABCA1 rs2066714T/C, rs2066715T/C, and rs2230808C/T between NAFLD patients and healthy controls. The ABCA1 rs1800977 A was independently associated with NAFLD after adjusting for the effects of age, gender, and BMI. Compared to the noncarriers in NAFLD patients, the carriers of ABCA1 rs2066714 C showed a significantly higher level of LDL (P = 0.045) and the carriers of ABCA1 rs2230808 T showed a significantly lower level of HDL (P = 0.039). Conclusions: We first demonstrated the association between the ABCA1 polymorphisms and the risk of NAFLD in a Chinese Han population. The ABCA1 rs1800977 may be a protective factor against the development of NAFLD. The ABCA1 rs2066714 C allele could increase the serum LDL cholesterol level, and the ABCA1 rs2230808 T allele could decrease the serum HDL cholesterol level in NAFLD patients. |
