Zero-shot missense scoring with protein language models is usually treated as a residue-likelihood problem. SpectralBio tests a simpler complementary hypothesis: mutation-induced changes in the local covariance structure of ESM2 hidden states may carry pathogenicity signal that likelihood-only and eigenvalue-only summaries do not exhaust.

Zero-shot missense scoring with protein language models is usually framed as a sequence-likelihood problem. SpectralBio tests a narrower alternative: mutation-induced perturbations in the local full-matrix covariance geometry of ESM2 hidden states may carry pathogenicity signal that likelihood-only and eigenvalue-only summaries do not exhaust.
