title: Comparison between the allelic frequency distribution of the Ha-ras 1 locus in normal individuals and patients with lymphoma, breast, and ovarian cancer.
abstract: Analysis of 426 alleles of the human Ha-ras 1 locus in DNA samples of cancer patients and controls reveals no obvious association between specific restriction fragments and a genetic predisposition to malignancy. However, differences in the allele distribution in leukocyte and tumour DNAs of cancer patients may be related to an involvement of the Ha-ras 1 gene in tumorigenesis.
