In the German subjects at increased risk for type 2 diabetes, SNPs rs2721068 and rs17446614 were significantly (P = 0.0045 and P = 0.0018, respectively) and SNPs rs17446593 and rs2297627 were nominally (P = 0.0091 and P = 0.0387, respectively) associated with beta-cell dysfunction. rs2721068, rs17446614, and rs2297627 were also nominally associated with impaired glucose tolerance (P = 0.0264, P = 0.0162, and P = 0.0221, respectively).
An intronic SNP rs2297627 associated with early-onset T2D [OR = 1.34 (1.13-1.58), P = 8.7 × 10(-4)] and T2D onset at any age [OR = 1.19 (1.09-1.30), P = 1 × 10(-4) ].
In the German subjects at increased risk for type 2 diabetes, SNPs rs2721068 and rs17446614 were significantly (P = 0.0045 and P = 0.0018, respectively) and SNPs rs17446593 and rs2297627 were nominally (P = 0.0091 and P = 0.0387, respectively) associated with beta-cell dysfunction. rs2721068, rs17446614, and rs2297627 were also nominally associated with impaired glucose tolerance (P = 0.0264, P = 0.0162, and P = 0.0221, respectively).
There were six of 1096 single nucleotide polymorphisms in five genes potentially associated with type 2 diabetes: tachykinin receptor 3 (rs1384401), anaplastic lymphoma receptor tyrosine kinase (rs4319896), calcium channel, voltage-dependent, L type, alpha 1D subunit (rs12487452), FOXO1A (rs10507486 and rs7323267), and v-akt murine thymoma viral oncogene homolog 3 (rs897959).
In the German subjects at increased risk for type 2 diabetes, SNPs rs2721068 and rs17446614 were significantly (P = 0.0045 and P = 0.0018, respectively) and SNPs rs17446593 and rs2297627 were nominally (P = 0.0091 and P = 0.0387, respectively) associated with beta-cell dysfunction. rs2721068, rs17446614, and rs2297627 were also nominally associated with impaired glucose tolerance (P = 0.0264, P = 0.0162, and P = 0.0221, respectively).
Together, these results indicate that the rs17592236 polymorphism is associated with decreasing of HCC hereditary susceptibility likely through modulating the binding affinity of miR-137 to the 3'UTR in FOXO1 messenger RNA (mRNA).
In the German subjects at increased risk for type 2 diabetes, SNPs rs2721068 and rs17446614 were significantly (P = 0.0045 and P = 0.0018, respectively) and SNPs rs17446593 and rs2297627 were nominally (P = 0.0091 and P = 0.0387, respectively) associated with beta-cell dysfunction. rs2721068, rs17446614, and rs2297627 were also nominally associated with impaired glucose tolerance (P = 0.0264, P = 0.0162, and P = 0.0221, respectively).
Single nucleotide polymorphisms genotyping of rs12762303 and rs2297627, in ALOX5 and FOXO1 genes were demonstrated a significant correlation between mutant allele and the risk of CAD, respectively.
In the German subjects at increased risk for type 2 diabetes, SNPs rs2721068 and rs17446614 were significantly (P = 0.0045 and P = 0.0018, respectively) and SNPs rs17446593 and rs2297627 were nominally (P = 0.0091 and P = 0.0387, respectively) associated with beta-cell dysfunction. rs2721068, rs17446614, and rs2297627 were also nominally associated with impaired glucose tolerance (P = 0.0264, P = 0.0162, and P = 0.0221, respectively).
Investigating the relevance of our findings in a separate cohort, we found that SNP rs2721068 was significantly associated with type 2 diabetes in the additive (P = 0.002) and dominant model (P = 0.009) in Finnish men.
Multifactor dimensionality reduction (MDR) analysis showed that the interaction between SNPs rs7986407 and rs4325426 in FOXO1 gene and waist was the best model confirmed by interaction analysis, closely associating with T2DM.
There was an increased risk for T2DM in the case of non-obesity with genotype combined AA/CC, AA/AC or AG/AA for rs7986407 and rs4325426, and obesity with genotype AA for rs7986407 or AA for rs4325426 (OR = 3.976; 95% CI = 1.156-13.675; P value from sign test [P(sign)] = 0.025; P value from permutation test [P(perm)] = 0.000-0.001).
The risk of T2DM in individuals with AA genotype for rs7986407 and CC genotype for rs4581585 in FOXO1 gene was 2.092 and 2.57 times higher than that with GG genotype (odds ratio [OR] = 2.092; 95% confidence interval [CI] = 1.178-3.731; P = 0.011) and TT genotype (OR = 2.571; 95% CI = 1.404-4.695; P = 0.002), respectively.
