KRASMutationDraft, not yet medically reviewed

KRAS G12C

A specific KRAS change with dedicated inhibitors, discussed in advanced lung cancer.

Parent marker: KRAS

Not a diagnosis and not final medical advice. Must be reviewed by a doctor.

Clinical meaning

G12C is one of the KRAS changes that can be directly targeted. The discussion includes G12C inhibitors and combinations that are currently under investigation.

How this finding appears in a report

Reports need to mention specific variants, as these inhibitors do not work on other KRAS alterations.

When therapy stops working

Resistance may arise through secondary changes in KRAS or activation of other pathways such as RAS-MAPK.

What needs verification

  • Complete variant name as written in the laboratory report.
  • Examination methods and types of samples used.
  • Examination dates were compared with ongoing therapy.

Marker context: KRAS

KRAS G12C alterations have specific inhibitor options, while other alterations are generally directed to standard pathways or clinical trials. KRAS mutations often appear together with other markers such as STK11 or KEAP1, which can also influence the discussion.

A negative result does not always mean absent

Test sensitivity differs by sample type and method. Results need to be read together with the pathology report and clinical condition.
