In summary, we have a model that discovers and predicts: 151 genome-wide significant loci, biological subtypes inside single diagnoses, and 348-disease that outperforms existing clinical tools. Years in the making, SO thankful for an incredible team!!! Paper, code, interactive ht

Two things evolve smoothly in time: the signatures themselves (φ), and each person's loading on them (λ) — anchored in germline genetics, so the model builds from and reveals new biology, rather than black box artifacts. Then Bayesian updating does the work: every new diagnosis

But patients don't sit still. How much a signature matters to you depends on when you ask the question. Three patients, three trajectories, distinct from the next patient who shares the same diagnosis. Same phenotype, different biology. https://t.co/AAEnEsHana

At its core are signatures: latent patterns of how disease co-occur and unfold over time, learned from data with no supervision. The model discovers, for instance, an ischemic cardiovascular signature which appropriately describing the sequence of events from hypercholesterolemia

One of my first consults as a cardiology fellow: a 34-year-old, textbook MI. A day earlier, no risk model would have flagged him for prevention. That paradox has driven my work ever since — our models miss how disease actually evolves, dynamically, on top of a genetic background.

Risk isn't a number you're born with or a snapshot at a clinic visit. It lives in three dimensions at once — time, disease, and the individual. As a patient walks through life, her journey can take many forms. So we built Aladynoulli to model these patterns dynamically. https://
