Deep dive asks whether AlphaGenome Atlas's precomputed 9bn-variant lookup is a real unlock

A non-geneticist's close read of DeepMind's AlphaGenome Atlas preprint questions its significance: the team precomputed 9bn single-base changes plus 100m indels, turning per-variant inference into lookup, plus an AVI score and motif map. Concerns: predictions aren't measurements; the headline clinical result (29.5% top-50 recall on solved GREGoR cases vs 12.5% for CADD) is retrospective; only 4 of 25 rare-variant findings nominally replicated in All of Us, none surviving Bonferroni. The DNM1 deep-intronic case stands out, but is it representative? Would clinical geneticists actually use it, and is precomputation the real unlock or framing on an incremental gain?
