Hypothesis
The study investigates the relationship between the apoA1 -75 G/A polymorphism and lipoprotein(a) levels in a high-risk Omani population.
Conclusion
The apoA1-75 G/A (M1-) polymorphism is associated with higher Lp(a) levels, indicating a potential risk for cardiovascular disease.
Supporting Evidence
- The M1- allele frequency was found to be 19.2% in the studied population.
- Subjects with the M1- allele had a mean Lp(a) concentration significantly higher than those with the M1+ allele.
- The study included both diabetic and non-diabetic subjects, showing consistent results across both groups.
Takeaway
Some people have a gene change that makes a substance in their blood called Lp(a) higher, which can be bad for their heart.
Methodology
Blood samples were collected from 90 non-diabetic and 149 diabetic subjects to study genotype and phenotype.
Potential Biases
Potential confounding factors such as diabetes and metabolic syndrome prevalence in the population.
Limitations
The sample size for homozygous minus alleles was small, and other lipoprotein parameters did not reach statistical significance.
Participant Demographics
90 non-diabetic and 149 type 2 diabetes mellitus subjects, with a mix of genders.
