Congrats to Wei-Yu, Sang-Ho, @raimondi_ivan and the whole team! Grateful to @TheMarkFdn @SMaHTnetwork @cegs_ica for the support

[Ben Adler @ben_a_adler]

Saying it because @kenjmloi didn't:
This is really close to a RNA system that targets protein sequences because of wobble bases in codons.

Truly amazing discovery!

🚨NEW FDA Draft Guidance Safety Assessment of Genome Editing in Human Gene Therapy Products Using Next-Generation Sequencing #FDA #Regulatory #geneediting #genetherapy
Top 5 Takeaways -
1) NGS becomes the regulatory backbone for genome editing safety
2) FDA expects a layered, redundant approach to off-target assessment
3) Low-frequency events matter and must be detectable
4) Patient genetics is now explicitly part of risk assessment
5) Genome integrity (translocations) is no longer optional for DSB-based gene editing systems

Champions ⭐️⭐️⭐️ Phenomenal win for Team India in Ahmedabad. Absolutely no match for the explosive cricket played by us throughout the tournament. Brilliant character shown by the boys to keep fighting in tough situations and become world champions once again. Congratulations to all the players and all the members of the management for achieving this feat. Jai Hind 🇮🇳❤️

AlphaGenome: Decoding the dark matter of the genome with a unified deep learning model

More than 98% of human genetic variation lies outside protein-coding regions. These "non-coding" variants can disrupt gene regulation in remarkably diverse ways: altering chromatin accessibility, shifting 3D genome architecture, modifying splicing, or changing expression levels—often in tissue-specific patterns. Yet existing computational models face a fundamental trade-off: either they capture long-range regulatory interactions (like distant enhancers) but blur fine-scale features, or they achieve nucleotide resolution but miss distal context. And most specialize in a single modality, leaving users to stitch together predictions from many separate tools.

Žiga Avsec and coauthors at Google DeepMind present AlphaGenome, a model that sidesteps these trade-offs. It takes 1 megabase of DNA as input and predicts ~6,000 genome tracks—spanning gene expression, splicing (sites, usage, and junctions), chromatin accessibility, histone modifications, transcription factor binding, and 3D contact maps—at up to single-base-pair resolution.

The architecture combines a U-Net backbone with transformer blocks: convolutions capture local motifs essential for splice sites and TF footprints, while transformers model long-range dependencies like enhancer–promoter interactions. Training uses a two-stage approach—pretraining on experimental data followed by distillation from an ensemble of teachers using mutationally perturbed sequences—yielding a single model that scores variants across all modalities in one pass.

The results are striking: AlphaGenome achieves state-of-the-art performance on 25 of 26 variant effect prediction benchmarks, including a 25% improvement in predicting eQTL direction over the previous best model. It outperforms specialized models on their own tasks—beating SpliceAI-class methods on 6 of 7 splicing benchmarks and ChromBPNet on accessibility QTLs. Critically, the multimodal outputs enable mechanistic interpretation: for oncogenic mutations near the TAL1 gene in T-cell leukemia, AlphaGenome simultaneously predicts neo-enhancer formation (increased H3K27ac), chromatin opening, and elevated gene expression—recapitulating experimentally validated mechanisms.

This points toward a future where interpreting non-coding variation no longer requires assembling a patchwork of specialized models. A unified framework that jointly predicts molecular consequences across modalities could accelerate rare disease diagnostics, guide therapeutic oligonucleotide design, and help prioritize variants in GWAS loci—moving us closer to truly reading the regulatory code written in DNA.
