Hypothesis
Is there an association between the INSIG-2 promoter polymorphism and obesity-related phenotypes?
Conclusion
The study found no association between the INSIG-2 polymorphism and obesity-related phenotypes in the examined population.
Supporting Evidence
- The study included 1428 individuals from 248 families.
- No significant association was found between the SNP and obesity-related traits.
- The families were selected through a proband with hypertension.
Takeaway
The study looked at a gene to see if it affects weight, but it turns out it doesn't really matter for most people.
Methodology
The study involved genotyping a specific SNP in a large family cohort and measuring various obesity-related traits.
Potential Biases
Selection bias could be a concern since families were chosen through a hypertensive proband.
Limitations
The study may not have had enough power to detect small effects and was not selected for obesity.
Participant Demographics
Participants were British Caucasian families, mostly moderately overweight.
