Hypothesis

How many genes are involved in the susceptibility to venous thrombosis (VT) and what is their contribution to VT risk?

Conclusion

The study identified twelve SNPs associated with venous thrombosis risk, providing insights into the genetic factors contributing to the disease.

Supporting Evidence

  • Twelve SNPs reached genome-wide significance, indicating strong genetic associations with VT.
  • Common variants could explain about 35% of the genetic variance underlying VT susceptibility.
  • Chromosome 20 was found to contribute approximately 7% of the total genetic variance for VT.

Takeaway

This study looked at how genes can make people more likely to get blood clots in their veins, finding some important genetic clues.

Methodology

A genome-wide association study (GWAS) was conducted with 1,542 cases and 1,110 controls, analyzing 551,141 SNPs.

Potential Biases

Controls were not matched to cases for gender and age, which could introduce bias.

Limitations

The study did not include patients with certain genetic risk factors, which may limit the generalizability of the findings.

Participant Demographics

Participants were mainly of French origin.
