KRAS mutation is a re-occuring theme in molecular pathology. KRAS is an oncogene.[1]

General

Kirsten RAS (KRAS) is a member of the Ras gene familiy, which encodes small G proteins with intrinsic GTPase activity.

Implication

Colorectal cancer

In the context of colorectal carcinoma:[8][9]

  • Patient must have wild type KRAS to get drugs; KRAS mutation predicts resistance to cetuximab (Erbitux) and panitumumab (Vectibix).
  • The vast majority of activating mutations are found in codon 12/13, 61 and 146.[10]
  • KRAS mutations are usually stable between primary and metastatic tumors. [11]
  • KRAS mutation predict poor response to FOLFOX treatment.[12]

Lung cancer

In the context of lung cancer:[13]

  • Mutations are rare in never-smokers.
  • KRAS G12C is the most common G > T transversion mutation in smokers.[14]
  • Biomarker for MEK inhibitors selumetinib and trametinib.

Gross

In colorectal carcinoma:

  • Typically right sided lesions.[7]
