Ha-ras polymorphisms in epithelial ovarian cancer.

Journal Article

Unusual restriction fragment length polymorphisms (RFLPs) of the Ha-ras locus have been found in DNA from leukocytes and tumor tissue of cancer patients. To determine whether rare alleles would be observed frequently in patients with ovarian cancer, Ha-ras RFLPs were studied in DNA from 42 different ovarian epithelial tumors and from the peripheral blood leukocytes of 76 normal individuals. Four common, seven intermediate, and seven rare alleles were detected overall. Similar fractions of rare alleles were found in DNA from ovarian cancers and from the peripheral blood of normal individuals. Thus, the frequency of unusual Ha-ras RFLPs did not distinguish patients with ovarian cancers from apparently healthy individuals.
