BackgroundAlthough solute carrier family 30 (zinc transporter) member 8 (SLC30A8) gene 807C/T polymorphism is associated with an increased risk of type 2 diabetes mellitus (T2DM) risk, there remains some inconsistency between individual studies.ObjectiveThe aim of the study is to explore the relationship between SLC30A8 gene 807C/T polymorphism and T2DM in the Chinese population.MethodsThe current meta-analysis compiles and analyzes the data of 6,942 participants from 10 independent studies. Either a fixed or random-effects model was adopted to evaluate the pooled odds ratio (ORs) and the corresponding 95% confidence interval (95% CI).ResultsA significant association between SLC30A8 gene 807C/T polymorphism and T2DM was found in the Chinese population under allelic (OR: 0.85, 95% CI: 0.80–0.91, P = 7.42 × 10−7), recessive (OR: 0.52, 95% CI: 0.38–0.72, P = 8.49 × 10−5), dominant (OR: 2.40, 95% CI: 1.68–3.41, P = 1.30 × 10−6), homozygous (OR: 0.52, 95% CI: 0.40–0.67, P = 2.90 × 10−7), heterozygous (OR: 0.79, 95% CI: 0.71–0.88, P = 1.63 × 10−5), and additive genetic models (OR: 0.73, 95% CI: 0.64–0.83, P = 7.05 × 10−7).ConclusionSLC30A8 gene 807C/T polymorphism was significantly associated with an increased T2DM risk in the Chinese population. Therefore, individuals of Chinese descent with the C allele of SLC30A8 gene 807C/T polymorphism may be more susceptible to developing T2DM, while individuals with the T allele may be protected against T2DM. |
