CHEK2

CHEK2 is a gene that produces a protein involved in repairing damaged DNA and helping prevent cancer. When functioning normally, CHEK2 acts as a tumor suppressor, alerting cells to fix or destroy abnormal cells that could develop into cancer. Certain inherited mutations in CHEK2 can impair its ability to do this job, increasing the risk for cancers such as breast, colon, and others. Knowing about CHEK2 mutations can help individuals and healthcare providers make informed decisions about cancer screening and prevention strategies.
