Recent reports have suggested that elevated chromosomal aberration yields following X-irradiation of skin fibroblasts in the G2 phase of the cell cycle are characteristic of affected members of cancer-prone families. These studies propose that this phenomenon is a consequence of impaired DNA repair and might be a useful predictor of genetic susceptibility to cancer. We have tested G2 chromosomal X-ray sensitivity in skin fibroblasts and peripheral blood lymphocytes from members of a kindred with the cancer family syndrome, a disorder in which susceptibility to colon cancer and other epithelial cancers is inherited in an autosomal dominant pattern. Further, using a cell survival assay, we tested cancer family syndrome skin fibroblasts for sensitivity to four classes of mutagens, including X-rays. In the assays used, skin fibroblasts and lymphocytes from both affected and unaffected family members exhibited responses indistinguishable from normal controls. Karyotypic analysis of lymphocytes and fibroblasts revealed no consistent constitutional cytogenetic abnormality. Thus, affected patients with the cancer family syndrome do not have increased sensitivity to irradiation and chemical mutagens and lack a germ-line chromosomal defect.
