KRAS

Universal Cellular Machinery · Cell Cycle Control & Mitotic Division

Does finding KRAS in a report mean the result came from a tumor?

KRAS encodes a normal signaling switch that relays growth and differentiation messages. A tumor-acquired alteration and an inherited finding need different interpretations, so the sample and exact variant must be identified.

Common Gene Name
KRas proto-oncogene, GTPase
NCBI Gene ID
3845
Chromosome
12
