The GABPB1 gene A/G polymorphism in Polish rowers

Area of Science:

• Genetics
• Sports Science
• Molecular Biology

Background:

• Nuclear respiratory factor 2 (NRF2), also known as GA-binding protein (GABP), regulates mitochondrial enzyme genes.
• GABPB1 gene variants, specifically the A/G polymorphism (rs7181866) in intron 3, are linked to endurance performance.
• Understanding genetic predispositions for athletic success is crucial in sports science.

Purpose of the Study:

• To investigate the association between the GABPB1 A/G polymorphism (rs7181866) and physical performance in Polish rowers.
• To determine if specific genotypes or alleles of GABPB1 are more prevalent in elite endurance athletes compared to sedentary individuals.

Main Methods:

• DNA was extracted from buccal cells of 55 Polish rowers and sedentary controls.
• Genotyping of the GABPB1 A/G polymorphism (rs7181866) was performed using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP).
• Genotype and allele frequencies were compared between the athlete and control groups.

Main Results:

• The frequency of the GABPB1 A/G genotype was significantly higher in rowers (10.91%) compared to controls (2.31%) (P = 0.012).
• The G allele frequency was also significantly elevated in rowers (5.50%) versus controls (1.17%) (P = 0.014).
• These findings suggest a potential genetic link between GABPB1 variants and endurance capacity.

Conclusions:

• The GABPB1 gene, particularly the A/G polymorphism (rs7181866), may serve as a genetic marker for endurance athletes.
• Further research involving other GABPB1 polymorphisms and genes in elite endurance athletes is recommended to validate these findings.
• This study contributes to understanding the genetic basis of athletic performance in endurance sports.
