Hypothesis

Genetic variation at the TERT-CLPTM1L locus is associated with susceptibility to ovarian and breast cancer.

Conclusion

The study found that certain genetic variants in the TERT promoter are linked to a decreased risk of ovarian and breast cancer.

Supporting Evidence

  • The study genotyped 36 SNPs in 2,130 invasive EOC cases and 3,975 controls.
  • The presence of minor alleles at specific SNPs was associated with decreased breast cancer risk.
  • Functional analyses showed that certain SNPs reduced TERT promoter activity.
  • The study included data from multiple international cancer research consortia.

Takeaway

Some tiny changes in our genes can help protect us from getting certain types of cancer, like ovarian and breast cancer.

Methodology

The study used fine-mapping and functional analyses of SNPs in the TERT promoter region across multiple case-control studies.

Potential Biases

Potential biases may arise from the selection of case-control studies and the genetic background of participants.

Limitations

The study primarily focused on Caucasian populations, which may limit the generalizability of the findings.

Participant Demographics

Participants were primarily Caucasian, including 2,130 invasive EOC cases and 3,975 controls.
