KRAS Alleles: The Devil Is in the Detail

Open access
Haigis, Kevin M.·2017·Trends in Cancer

Abstract

KRAS is the most frequently mutated oncogene in cancer and KRAS mutation is commonly associated with poor prognosis and resistance to therapy. Since the KRAS oncoprotein is, as yet, not directly druggable, efforts to target KRAS mutant cancers focus on identifying vulnerabilities in downstream signaling pathways or in stress response pathways that are permissive for strong oncogenic signaling. One aspect of KRAS biology that is not well appreciated is the potential biological differences between the many distinct KRAS activating mutations. This review draws upon insights from both clinical and experimental studies to explore similarities and differences among KRAS alleles. Historical and emerging evidence supports the notion that the specific biology related to each allele might be exploitable for allele-specific therapy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • G12D and G12V mutations are the most common in pancreatic ductal adenocarcinoma, followed by G12R.

    “G12D and G12V mutations are the most common in PDAC, followed by G12R.”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [32]

    The Epidemiology of KRAS Alleles section identifies G12D as the most common allele in PDAC. The KRAS Allelic Variation section says codon 12 mutations predominate, but the text in our copy does not establish that G12V is second most common or that G12R follows it in PDAC. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • KRAS G12R, G13D, Q61H, Q61L, and A146T mutations have increased intrinsic exchange relative to wildtype, but G12C and G12V do not display large changes.

    “KRAS G12R, G13D, Q61H, Q61L, and A146T mutations have increased intrinsic exchange relative to wildtype, but G12C and G12V do not display large changes [4,29,30,31,32].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [32]

    The Biochemistry of KRAS Alleles section (page unavailable) says codon 13 mutants increase intrinsic exchange and A146 mutations markedly promote exchange, supporting the G13D and A146T portions at the codon level. It also says most codon 12 mutants do not change exchange, broadly consistent with G12C and G12V. It does not establish increased exchange for G12R, Q61H, or Q61L; it discusses Q61 mutants chiefly in terms of reduced hydrolysis. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • G12C and G12V mutations are predominant in lung adenocarcinomas with smoking-associated mutational signatures.

    “G12C and G12V mutations are predominant in lung adenocarcinomas with smoking-associated mutational signatures [30,32].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [32]

    The “KRAS Allelic Variation” section says G12C and G12V are the most frequent KRAS mutations in non-small cell lung cancer and arise from a classical smoking-induced transversion. It does not establish their predominance specifically in lung adenocarcinomas with smoking-associated mutational signatures. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Specific KRAS mutations show characteristic patterns of tissue preference.

    “Specific KRAS mutations show characteristic patterns of tissue preference (Figure 1b,c).”
  • KRAS A146 mutations are primarily found in colorectal cancer and are rarely reported in other types.

    “KRAS A146 mutations are primarily found in colorectal cancer and are rarely reported in other types.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
