MET in NSCLC

c-Met (MET) protein expression, METex14 skipping mutation, MET focal gene amplification

BIOLOGY

Under normal conditions, the HGF/MET pathway is responsible for cell functions such as growth and proliferation. Dysregulation of this pathway can lead to oncogenic changes such as tumor cell growth, invasion, and metastasis. Multiple mechanisms are implicated in MET dysregulation including protein expression, gene amplification, and gene mutation.1​

Testing Considerations

Testing modality differs based on the type of MET aberration under investigation. There is no single test that can identify all 3 MET aberrations.1​
