Association between the related gene polymorphisms and clinical features of Han population with type 2 diabetes mellitus in Qinhai region
Objective To investigate the association between polymorphic susceptibility loci for diabetes mellitus and clinical characteristics of type 2 diabetes mellitus(T2DM)in the Han Chinese population in the Qinghai region.Methods A total of 286 T2DM patients treated in Qinghai Provincial People's Hospital from December 2021 to July 2023 were selected as the study subjects.DNA samples were sequenced by Illumina sequencing.LASSO regression model and Kolmogorov-Smirnov(K-S)test were used to analyze the association between SNP and age of onset in T2DM patients.Logistic regression model was used to analyze the association between SNP and DM family history,FPG,HbA1c,HOMA-IR and HOMA-β.Results The age of onset,smoking history,drinking history and WC of male patients were higher than those of female patients(P<0.05),and the HOMA-β,HDL-C,LDL-C and TC were lower than those of female patients(P<0.05).LASSO regression model and K-S test analysis showed that 7 SNPs were associated with the age of onset of T2DM(P<0.05).Logistic regression analysis showed that 13 SNPs were correlated with family history of DM(P<0.05),13 SNPs were correlated with FPG(P<0.05),11 SNPs were correlated with HbA1c(P<0.05),20 SNPs were correlated with HOMA-IR(P<0.05),16 SNPs were associated with HOMA-β(P<0.05).Conclusions In Chinese Han patients with T2DM in Qinghai province,multiple SNPs variants may affect the disease phenotype through different biological pathways,including age of onset,blood glucose index and islet function.
