Point mutations of <i>ras</i> genes in human adrenal cortical tumors: Absence in adrenocortical hyperplasia

Abstract excerpt

Point mutations of ras genes (K-, H-, and N-ras) at codons 12, 13, and 61 and of the Gi2 alpha gene at codons 179 and 205, were studied in 56 primary adrenal cortical tumors and 6 adrenal cortical hyperplasias. Of 56 tumors, 24 were carcinomas and 32 were benign. The 24 carcinomas and 20 of the benign tumors were from American patients; the 12 remaining adenomas were from Japanese patients. Of the benign tumors...
