Insights
This study investigated thrombosis-related gene polymorphisms in morbidly obese patients. Key gene variants, including MTHFR, were not significantly associated with morbid obesity or related traits in European subjects.
Area of Science:
- Genetics
- Obesity Research
- Thrombosis
Background:
- Obesity is a significant risk factor for thrombotic complications.
- Understanding the genetic predisposition to thrombosis in obesity is crucial for risk stratification and management.
- Specific gene polymorphisms in ABO, F5, MTHFR, and FGG have been implicated in thrombotic events.
Purpose of the Study:
- To determine the frequency of specific thrombosis-related gene polymorphisms (ABO, F5, MTHFR, FGG) in morbidly obese patients.
- To compare the distribution of these gene polymorphisms between morbidly obese individuals and nonobese controls.
- To assess the association of these polymorphisms with anthropometric measures like height and weight in the studied populations.
Main Methods:
- Genotyping of single nucleotide polymorphisms (SNPs) in ABO (rs505922), F5 (rs6427196), MTHFR (rs1801133), and FGG (rs6536024) was performed using RT-PCR.
- The study included 320 morbidly obese patients (BMI > 40 kg/m²) and 303 nonobese control individuals (BMI < 30 kg/m²).
- All participants were of European descent.
Main Results:
- No significant differences were observed in the overall distribution of genotypes and alleles for the studied SNPs between morbidly obese and nonobese groups.
- A non-significant tendency was noted for the MTHFR rs1801133 TT genotype to be linked with morbid obesity (OR 1.84, P=0.129).
- The distribution of height and weight means did not significantly differ among individuals carrying different genotypes of the investigated SNPs.
Conclusions:
- The investigated gene polymorphisms (ABO C>T, F5 C>G, MTHFR C>T, FGG C>T) were not found to be associated with morbid obesity in the European cohort studied.
- These specific genetic variations do not appear to be significant risk factors for height, weight, or morbid obesity in this population.
- Further research may be needed to explore other genetic or environmental factors contributing to thrombosis risk in obese individuals.
Abstract:
Objective. Obesity is a well-known risk factor for thrombotic complications. The aim of the present study was to determine the frequency of thrombosis related ABO, F5, MTHFR, and FGG gene polymorphisms in morbidly obese patients and compare them with the group of nonobese individuals. Methods. Gene polymorphisms were analyzed in 320 morbidly obese patients (BMI > 40 kg/m2) and 303 control individuals (BMI < 30 kg/m2) of European descent. ABO C>T (rs505922), F5 C>G (rs6427196), MTHFR C>T (rs1801133), and FGG C>T (rs6536024) SNPs were genotyped by RT-PCR. Results. We observed a tendency for MTHFR rs1801133 TT genotype to be linked with morbid obesity when compared to CC genotype; however, the difference did not reach the significant P value (OR 1.84, 95% CI 0.83-4.05, P = 0.129). Overall, the genotypes and alleles of rs505922, rs6427196, rs1801133, and rs6536024 SNPs had similar distribution between morbidly obese and nonobese control individuals. Distribution of height and weight means among individuals carrying different rs505922, rs6427196, rs1801133, and rs6536024 genotypes did not differ significantly. Conclusions. Gene polymorphisms ABO C>T (rs505922), F5 C>G (rs6427196), MTHFR C>T (rs1801133), and FGG C>T (rs6536024) were not associated with height, weight, or morbid obesity among European subjects.
