Background: Several studies have reported that apolipoprotein A5(APOA5) is involved in the development of non-alcoholic fatty liver disease(NAFLD). However, no research has been performed regarding the association between APOA5 polymorphisms and the risk of NAFLD. This study aimed to explore the association between APOA5 gene polymorphisms and NAFLD in a Chinese Han population.Methods: Genotypes of the SNPs(rs10750097, rs1263173, rs17120035, rs3135507 and rs662799) of APOA5 in 232 NAFLD patients and 188 healthy controls were determined using polymerase chain reaction(PCR)analysis. Clinical characteristics were measured using biochemical methods.Results: The five single nucleotide polymorphisms(SNPs)(rs10750097, rs1263173, rs17120035, rs3135507 and rs662799) of APOA5 showed no significant association with NAFLD(P 0.05). The rs10750097 with G allele showed a higher serum level of alkaline phosphatase(ALP) compared with C allele in overall series and NAFLD patients(P 0.05). The rs1263173(A/A) carriers showed a higher level of glucose compared to the non-carriers in overall series(P 0.05). The rs17120035(T/T) carriers showed a lower plasma TG level in overall series and NAFLD patients(P 0.05), and the rs662799(G/G) carriers showed higher levels of plasma triglyceride(TG), ALP, and lower level of high-density lipoprotein(HDL) compared to non-carriers in NAFLD patients(P 0.05). No significant difference were observed on the clinic parameters of APOA5 rs3135507(T/T) carriers in both group of overall series and NAFLD patients(P 0.05).Conclusions: The five SNPs(rs10750097, rs1263173, rs17120035, rs3135507 and rs662799) of APOA5 gene are not associated with the risk of NAFLD in the Chinese Han population. The genotypes of rs10750097(G/G), rs1263173(A/A), rs17120035(T/T), and rs662799(G/G) performed a significant effect on clinic characteristics in overall series and NAFLD patients, indicating that these polymorphisms may be associated with NAFLD. |
