Lysines K117 and K147 play conserved roles in Ras activation from Drosophila to mammals. (PubMed, G3 (Bethesda))
Although RasG12V,K147R did not show compelling or quantifiable differences from RasG12V, RasG12V,K117R showed visible and quantifiable suppression compared to RasG12V, and triple mutant RasG12V,K117R,K147R showed dramatic suppression compared to RasG12V and increased suppression compared to RasG12V,K117R. These data are consistent with highly conserved roles for K117 and K147 in Ras activation from flies to mammals.

Clinical impact ofKRASG12, G13, Q61, K117 and A146 mutations in patients with colorectal liver metastases (AACR 2022)
For the subgroup of patients who carried a KRAS mutation and were treated with bevacizumab and doublet or triplet chemotherapy (N=156), clinical outcome was evaluated and pretreatment tumor burden was quantified as liquid biopsy circulating tumor DNA (ctDNA) mutant allele fraction (MAF) and as total tumor volume (TTV) on CT imaging... Of the 156 patients with a KRAS mutated tumor, most carried a KRAS G12 mutation (N=112, 71.8%), followed by mutations in G13 (N=15, 9.6%), A146 (N=12, 7.7%), Q61 (N=9, 5.8%) and K117 (N=5, 3.2%). High plasma ctDNA levels were observed for patients carrying a KRAS A146 mutation versus those with a KRAS G12 mutation, with a median MAF of 48% versus 19%, respectively. Radiological TTV revealed this difference to be associated with a higher tumor load in patients harboring a KRAS A146 mutation (median TTV 672 cm3 (A146) versus 74 cm3 (G12), p=0.036).

KRAS A146 Mutations Are Associated With Distinct Clinical Behavior in Patients With Colorectal Liver Metastases. (PubMed, JCO Precis Oncol)
Patients with mCRC with a KRAS A146 mutation represent a distinct molecular subgroup of patients with higher tumor burden and worse clinical outcomes, who might benefit from more intensive treatments. These results highlight the importance of testing colorectal cancer for all KRAS mutations in routine clinical care.

[VIRTUAL] Clonal and subclonal mutational landscapes in circulating tumor DNA in metastatic colorectal cancer: An exploratory analysis from the phase III PARADIGM study (AACR-II 2020)
The clonal and subclonal mutational landscapes of RAS WT pts were analyzed using a mCRC-focused custom ctDNA sequencing panel. Randomized pts (1:1) received mFOLFOX6 plus either panitumumab or bevacizumab. The validated ultra-deep plasma sequencing panel was concordant with tissue sequencing and detected tumor heterogeneity. The PARADIGM study will report the efficacy of anti-EGFR/VEGF therapies; post-treatment collection of ctDNA is ongoing. The relationship between therapeutic effects and clonal and subclonal mutational landscapes will be examined in the future.
