Nat Commun: Cross-ethnic genome-wide association meta-analysis to identify breast cancer risk sites

Breast cancer is one of the most common cancers among women in the world, with 2.
1 million new cases and 627,000 deaths in 2018

Studies have shown that genetic factors have a significant contribution to the risk of breast cancer, but the related molecular mechanisms have not yet been fully elucidated

Breast cancer is one of the most common cancers among women in the world, with 2.

Previous studies have shown that genome-wide association studies ( GWAS ) have successfully identified about 200 genetic mutation risk sites with low penetrance that are common in the disease
.

These identified risk sites also provide clues to the mechanisms related to the occurrence and development of breast cancer

The results showed that the cross-ethnic approach identified four overall breast cancer risk sites (1p13.

All in all, the results of the study revealed that there is a consistent association between breast cancer risk sites in African and European populations
.

The study also shows that cross-ethnic analysis can help improve the understanding of breast cancer genetics and identify related causal variants
