Finding synthetic-lethal partners for KRAS G12C: a graph traversal
Which functionally-coupled partners of KRAS are still development whitespace?
The question
Operator-authored prose pending
the strategic R&D question: how to find development whitespace partners for KRAS that are functionally coupled enough to be worth a screen — operator writes this section as long-form prose, ~150–250 words, footnoted, slow. Scaffold only.
Strategic context
Operator-authored prose pending
KRAS G12C landscape: sotorasib + adagrasib approvals, the rapid acquisition of resistance, why combinations matter, why synthetic-lethal partners are the most promising combination space — operator writes this section as long-form prose, ~150–250 words, footnoted, slow. Scaffold only.
The Mosaic-derived answer
Operator-authored prose pending
interpret the figure: which partners cleared the whitespace bar, why each matters, what the score is telling you, and how to read the 'outside-KG' partners — operator writes this section as long-form prose, ~150–250 words, footnoted, slow. Scaffold only.
The graph reasoning, step by step
Operator-authored prose pending
the traversal in five lines: anchor target → coess+PPI+shared-pathway union → patent/compound activity filter (< 5 patents, no clinical compound) → whitespace_score ranking → suggested_approach generator — operator writes this section as long-form prose, ~150–250 words, footnoted, slow.

Implications
Operator-authored prose pending
what a med-chem team takes from this: which partner to prioritise for an in-vitro CRISPR screen first, which to deprioritise because patent activity is already crowding, which to bring up at IC — operator writes this section as long-form prose, ~150–250 words, footnoted, slow. Scaffold only.
Limitations & honesty
Operator-authored prose pending
scoring is heuristic; co-essentiality is partial (Mosaic-vs-all-genes only); patent counts are noisy; not every high score reflects a tractable target — operator writes this section as long-form prose, ~150–250 words, footnoted, slow. Scaffold only.
