KRAS Gly12Cys (KRAS G12C)

Target
KRAS G12C
Molecular classification
Small GTPase, Oncogene
01

Overview

KRAS G12C is a specific mutation in the KRAS gene, where glycine at codon 12 is replaced by cysteine. This mutation causes the K-Ras protein to become constitutively active, driving uncontrolled cell growth and contributing to tumorigenesis, particularly in non-small cell lung cancer, colorectal cancer and other solid tumors. It is a target for small molecule inhibitors like sotorasib and adagrasib.
