title: Abnormalities of human chromosome 13 and in vitro radiosensitivity; a study of 19 fibroblast strains.
abstract: The in vitro X-ray sensitivity of 19 fibroblast strains derived from patients bearing a deletion, trisomy, inversion, or translocation of all or part of chromosome 13 were determined with a clonogenic survival assay. The results were compared with data from similar experiments involving strains from normal controls and from individuals trisomic for 3 other autosomes. The results suggest the involvement of this chromosome with hypersensitivity to the cytotoxic effects of X-irradiation. Experiments involving the partial monosomies and trisomies seem to implicate a locus on 13q14.
