Carriers of A-T, such as the parents of a person with A-T, have one mutated copy of the ATM gene and one normal copy. They are generally healthy, but there is an increased risk of breast cancer in women. This finding has been confirmed in a variety of different ways, and is the subject of current research. Standard surveillance (including monthly breast self-exams and mammography at the usual schedule for age) is recommended, unless additional tests are indicated because the individual has other risk factors (e.g., family history of breast cancer).

有两个坏ATgene是这个病，小孩在美国活到25岁，中国10岁
