The expression of aphidicolin-induced fragile sites in familial breast cancer patients.

Abstract

The expression frequency of aphidicolin-induced fragile sites was examined in familial breast cancer patients to determine whether this parameter could be used as a marker of genetic susceptibility in at-risk individuals. No difference was found in expression frequency between the breast cancer patients and a group of normal individuals (p = 0.61). This indicates that the expression frequency of aphidicolin-induced fragile sites is not a suitable marker for assessing genetic susceptibility in familial breast cancer.
