AlphaGenome

Quick explainer1 min readIntermediate

AlphaGenome is a Google DeepMind AI model that predicts how a stretch of DNA, and small changes to it, affect what happens inside human cells.

In plain words

Small differences in DNA can change how strongly genes are switched on in cells, which helps shape human traits and disease. AlphaGenome takes a DNA sequence as input and predicts those effects. The newest version, AlphaGenome 2, makes predictions for one chosen cell type or cell state at a time instead of broad tissue averages. Google DeepMind says it finds nearly twice as many DNA variants that change gene activity as the earlier model. Scientists reach it through an API that is free for non-commercial use.

A quick example

Imagine a researcher studying a rare disease who has found a single-letter DNA change in a patient. They ask AlphaGenome how that change would affect gene activity in heart muscle cells, and use the prediction to decide which change to test in the lab first.

  • Predicting gene activity in specific cell types.
  • Exploring how DNA changes relate to traits and disease.
