ATM gene

The ATM gene provides instructions for making a protein that plays a crucial role in detecting and repairing DNA damage in cells. This process helps prevent mutations that could lead to cancer. When the ATM gene functions properly, it acts as a quality control system, maintaining genetic stability. Mutations or defects in this gene can impair DNA repair, increasing the risk of developing certain cancers, particularly breast cancer. Overall, the ATM gene is an important part of the body's natural defense against genetic mutations and helps ensure healthy cell function.
