Study on the Correlation of Fetuin A Gene Polymorphism and Lower Extremity Atherosclerosis with Type 2 Diabetes of Yi Nationality in Yunnan Province / 医学研究杂志

ABSTRACT

Objective To investigate the Allele and genotype frequency distribution of four single nucleotide polymorphisms(SNPs)sites (rs4917,rs491 8,rs1071592,rs2248690) in Fetuin A gene with type 2 diabetes and type 2 diabetes complicated by atherosclerosis of lower limb arteries(ALLA) in Yi Nationality of Chuxiong,and evaluated for association of Fetuin A polymorphisms with ALLA in type 2 diabetes.Methods Four SNPs in Fetuin A were genotyped in One hundred twenty normal controls,sixty one T2DM cases and sixty seven ALLA in type 2 diabetes by polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) and allelic specific primer-polymerase chain reaction(ASP-PCR).Results The CC genotype and Allele C of rs1071592 in normal controls was lower than those which ALLA in type 2 diabetes(P ＜ 0.01),and there were no significant differences in frequency of genotype and allele distributions in the polymorphism analysis of rs4917 (C/T),rs4918 (C/G),rs2248690 (A/T) in these three groups (P ＞ 0.05).Logistic regression analysis showedthe CC genotype of rs1071592 in Fetuin A were nominally associated with atherosclerosis of lower limb arteries of T2DM.Conclusion There existed polymorphism of4917(C/T),rs4918(C/G),rs2248690(A/T),rs1071592(C/A) of Fetuin A in Yi nationality of chuxiong.The CC genotype of rs1071592 might be genetic risk factors of type 2 diabetes complicated by ALLA.
