Hypothesis

The γ-secretase pathway may be associated with atherosclerosis.

Conclusion

The study concludes that disturbed γ-secretase signaling may play a role in the susceptibility for premature coronary atherosclerosis in males.

Supporting Evidence

  • The study analyzed a cohort of 780 patients with premature coronary atherosclerosis and 1414 controls.
  • Significant male-specific association was found with the APH1B Phe217Leu risk allele.
  • Reduced γ-secretase activity was observed in the presence of the Phe217Leu mutation.

Takeaway

This study found that a specific gene variation is linked to heart disease, but only in men.

Methodology

The study tested for association of a SNP in the γ-secretase component APH1B with premature coronary atherosclerosis in a Dutch cohort.

Limitations

The study's findings may not be generalizable to other populations, and the female sample size was small.

Participant Demographics

Dutch Caucasian cohort, 780 cases and 1414 controls, with a focus on male participants.
