Working with colleagues at St. Vincent's Hospital in Sydney, Martin identified two individuals who had the characteristics of hereditary nonpolyposis colorectal cancer, which is usually caused by a mutation that inactivates one of a person's two copies of the tumor suppressor gene MLH1, but who showed no signs of mutation.

When mutated, or not working properly, cells with abnormal tumor suppressor genes are more likely to grow out of control and lead to the development of cancer.
These suppressor genes are inactivated in tumors, and since cancer drugs work by reducing the activity of enzymes, they won't work on such suppressors because a drug can't inhibit a gene that is already inactivated.»
