Association of polymorphisms within P2RX4 with type 2 diabetes mellitus: a preliminary case-control study

Area of Science:

• Genetics and Molecular Biology
• Metabolic Diseases
• Pharmacogenomics

Background:

• Type 2 diabetes mellitus (T2DM) is a complex metabolic disorder with diverse etiologies.
• Purinergic receptors are implicated in various physiological processes and are hypothesized to contribute to T2DM pathogenesis.

Purpose of the Study:

• To investigate the association between genetic variations in purinergic receptors and the risk of T2DM.
• To identify specific genetic markers that may influence T2DM susceptibility in a defined population.

Main Methods:

• Genotyping of 300 T2DM patients and 300 healthy controls using Amplification Refractory Mutation System-Polymerase Chain Reaction (ARMS-PCR).
• Statistical analysis performed using SPSS V16.0.
• Analysis included allele and genotype frequencies, interaction effects, and haplotype analysis.

Main Results:

• The G allele of the rs25644A>G polymorphism was significantly associated with an increased risk of T2DM (OR = 1.51, 95% CI = 1.14-1.99, p = 0.003).
• This association was observed in dominant genotype models, indicating a heightened risk under specific genotypic conditions.
• Interactions between genotypes within the P2XR4 gene and the rs1169727/rs25644 haplotype (A/G) also increased T2DM risk.

Conclusions:

• The rs25644A>G polymorphism plays a significant role in the increased risk of T2DM in the studied population.
• Genetic variations in purinergic receptor genes, particularly P2XR4, are potential contributors to T2DM development.
• Further research is warranted to elucidate the precise mechanisms by which these genetic factors influence T2DM.
