1PB dataset precomputes all ~9 billion possible SNVs across the entire human genome

A retweeted post announces a massive genomics resource: variant effect predictions precomputed for all 9 billion possible single-nucleotide variants (SNVs) across 100% of the human genome, totaling 1 petabyte.

For comparison, AlphaFold DB (AFDB) is only 23-30 TB and covers the 1.5-2% protein-coding portion of the genome via 200M protein structures — making the new dataset over 30x larger in scale and far broader in coverage. Retweeter Anshul Kundaje (Stanford genomics professor) calls it huge.
