Hypothesis

Are variants in the APOE and ELN genes associated with subarachnoid hemorrhage?

Conclusion

This study suggests a role of the APOE gene in the etiology of aneurysmal SAH.

Supporting Evidence

  • No individual SNP at the APOE locus was associated with SAH after correction for multiple comparisons.
  • Haplotype analysis revealed significant association of the major haplotype in APOE with SAH.
  • The study failed to confirm previous reports of ELN association with aneurysmal SAH.

Takeaway

The study looked at how certain genes might be linked to a type of brain bleed called subarachnoid hemorrhage, finding a connection with one gene but not the other.

Methodology

The study involved genotyping 12 SNPs on APOE and 10 SNPs on ELN in a case-control design with 107 SAH cases and 202 matched controls.

Potential Biases

Potential bias due to population substructure was addressed using genomic control methods.

Limitations

The study's findings are limited to Caucasian individuals and may not apply to other populations.

Participant Demographics

309 Caucasian individuals, including 107 SAH cases and 202 matched controls.
