## Summary

A team led by Y. Hao and O. G. Troyanskaya published Seal, a transfer-learning framework that predicts gene expression and variant effects across 26 brain regions, 30 cell types, and 7 developmental stages.

Seal links genetic variants to transcriptional regulators in a spatiotemporal context. Applied to GWAS data, it identifies shared and distinct regulatory architectures across six neuropsychiatric conditions. In the Simons Simplex Collection autism cohort, Seal finds a significant burden of de novo regulatory variants in transient fetal excitatory neurons, revealing cell-type- and stage-specific effects. Benchmarks show transfer learning significantly lowers mean squared error (P = 0.01) and improves predictions for neurodevelopmental genes (P = 1.1×10⁻¹⁸). The authors declare no competing interests; funding came from the Simons Foundation and Flatiron Institute.

## Key points

- Seal models gene expression across 26 regions, 30 cell types, 7 developmental stages
- Finds de novo regulatory variant burden in fetal excitatory neurons in autism cohort
- Model code and data publicly available on GitHub and Zenodo

## Why it matters

Seal provides a spatiotemporal framework linking genetic variation to brain development and neuropsychiatric disease mechanisms, with publicly accessible code and data for further research.
