Abstract

Genetic polymorphism of the epidermal growth factor (EGF) receptor gene following Taq I digestion was compared between samples of genomic DNA from glioma-derived cell lines and Caucasoid and Japanese subjects. The same three allelic forms of the EGF receptor gene, marked by variant fragments of approximately 12.8,11.6 and 10.8 kb in size were common to both ethnic groups and the 12.8- and 11.6-kb fragments were found in the glioma-derived cell line DNA. A further variant fragment of approximately 13.8 kb in size has been shown to be thus far restricted to the Japanese. These data suggest that most allelic forms of the EGF receptor gene recognized by Taq I restriction fragment length polymorphism have a long evolutionary history and probably do not predispose to development of malignant glioma.
