The genetic polymorphism in the STK11 does not affect gestational diabetes

Area of Science:

• Genetics
• Endocrinology
• Metabolic Disorders

Background:

• Gestational diabetes mellitus (GDM) is a pregnancy complication linked to future metabolic disorders.
• The STK11 gene, involved in insulin signaling, is a potential candidate for GDM risk.
• Previous research suggests a link between the STK11 gene and diabetes.

Purpose of the Study:

• To investigate the association between the STK11 gene rs8111699 polymorphism and GDM in Saudi pregnant women.
• To determine if a specific STK11 gene variant contributes to GDM development in this demographic.

Main Methods:

• A case-control study involving 200 GDM cases and 300 non-GDM pregnant Saudi women.
• Genomic DNA extraction followed by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis for the STK11 rs8111699 (C528G) polymorphism.
• Comparison of anthropometric, clinical, and biochemical data between GDM and control groups.

Main Results:

• Biochemical analyses showed significant differences between GDM cases and controls (p < 0.05).
• Anthropometric and clinical data were comparable between the groups (p > 0.05).
• No statistically significant difference in genotype or allele frequencies of the STK11 rs8111699 polymorphism was observed between GDM and non-GDM groups (p=0.12).

Conclusions:

• The rs8111699 polymorphism in the STK11 gene is not associated with an increased risk of developing gestational diabetes mellitus in pregnant Saudi women.
• This specific genetic variant does not appear to play a role in GDM pathogenesis within the studied Saudi population.
• Further research may explore other genetic factors or environmental influences on GDM development in Saudi Arabia.
