A Large Study Found 72 New Gene Variants of Breast Cancer
The world’s largest collective study on the genetics of breast cancer found 72 new gene variants that can be responsible for increasing the risk of developing the disease.
For the study, more than 300 research groups were involved in the analysis of genetic data received from over 275,000 women from all around the globe. The scientists were able to identify 65 variations of genes that contributed to the development of cancer. Other 7 genes were identified specifically in association with breast cancers that lacked estrogen receptors.
Researcher Georgia Chenevix-Trench from the QIMR Berghofer Medical Research Institute in Australia says: “We know that breast cancer is caused by complex interactions between these genetic variants and our environment, but these newly discovered markers bring the number of known variants associated with breast cancer to around 180.”
