AI Article Synopsis

  • The study examined how specific gene variants affect obesity and metabolic markers in non-diabetic Chilean adults, focusing on the SLC16A11 gene and its rs75493593 polymorphism.
  • It involved 263 participants and used real-time PCR to analyze the association of this gene variant with various health metrics like insulin levels, body mass index (BMI), and lipid profiles through linear regression.
  • Findings revealed that the minor allele of the variant is common among Chileans and is linked to higher insulin levels and BMI, indicating potential early metabolic risks that could lead to type 2 diabetes.

Article Abstract

Objective: To study the association of gene variants with obesity and metabolic markers in nondiabetic Chilean adults.

Methods: This cross-sectional study included 263 non-diabetic adults. The genotype of the rs75493593 polymorphism of SLC16A11 gene was performed by real-time PCR. It's association with adiposity markers (body weight, BMI, waist circumference and fat mass percentage), metabolic markers (glucose, insulin, HOMA, leptin, total cholesterol, LDLc, HDLc, triglycerides, ALT, GGT and hsCRP) and blood pressure was analyzed by linear regression.

Results: The minor allele (T) of the gene (rs75493593) has a frequency of 29.7% among Chileans. Risk genotypes (GT and TT) were associated with a significant 1.49 mU/l increase in plasmatic insulin for each copy of the minor allele (95% CI: 0.12, 2.87, p < 0.05). This association remained significant after adjusting for socio-demographic variables, physical activity and smoking (1.36 mU/l, 95% CI: 0.16, 2.58 p < 0.05), but was lost when BMI was included as a confounding factor. Higher BMI was also significantly associated with polymorphic genotypes in , independent of socio-demographic variables.

Conclusion: The minor allele of the gene (T) is highly prevalent among Chileans and is associated with increased insulin and BMI in nondiabetic individuals. These findings suggest that the genetic variant in is not only associated with type 2 diabetes as previously shown in Mexicans, but is also related to early metabolic alterations in healthy subjects that may lead to type 2 diabetes.
