Gene Summary

This gene, a Kirsten ras oncogene homolog from the mammalian ras gene family, encodes a protein that is a member of the small GTPase superfamily. A single amino acid substitution is responsible for an activating mutation. The transforming protein that results is implicated in various malignancies, including lung adenocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma. Alternative splicing leads to variants encoding two isoforms that differ in the C-terminal region. [provided by RefSeq, Jul 2008]

A Clinicopathologic and Molecular Analysis of 34 Mediastinal Germ Cell Tumors Suggesting Different Modes of Teratoma Development

Mediastinal teratomas can be both malignant and benign. Increased 12p copy numbers are uniform in malignant testicular germ cell tumors (GCT), so the 12p copy numbers were analyzed in mediastinal GCTs to see if this is indicative of malignancy. FISH analysis was used with our KRAS and chromosome 12 centromere probes to look for 12p copy number increases. The sensitivity for increased 12p copies for malignant GCT was 69%. This is less than reports for other tumors, and a negative test for increased 12p copies should not necessarily rule out malignancy.
