Identify new genetic marker for breast cancer
An international group of scientists announced that it has identified a new genetic marker for breast cancer.
According to scientists at Cancer Center Memorial Sloan-Kettering and the National Cancer Institute, women with this DNA variation are 1.4 times more risk of breast cancer than those who do not.
“These results are promising because they indicate a new molecular pathway that may be linked to breast cancer,” said Kenneth Offit, director of the study in a report released Thursday by the journal Proceedings of the National Academy of Sciences.
The investigation was carried out with a new method that distinguishes the genetic variations that alter the genome and the individual features of DNA.
According to scientists, these alterations are more frequent in individuals with certain diseases.
Although the risk associated with this marker is less than that of other gene mutations, their discovery will increase knowledge about the variations that contribute to breast cancer, the scientists said.
Offit added that the new genetic marker will not have immediate clinical implications or some impact on the guidelines for determining the existence of breast cancer.
