# grimage2
Mortality-risk epigenetic clock combining ten blood DNAm surrogate biomarkers with chronological age and sex; the Cox linear predictor is calibrated to an age-like value in years.
| | |
|---|---|
| **Predicts** | mortality risk |
| **Species** | Homo sapiens |
| **Tissue** | whole blood |
| **Data type** | DNA methylation |
| **Model type** | elastic net Cox regression |
| **Year** | 2022 |
## Use with pyaging
```python
import pyaging as pya
pya.pred.predict_age(adata, ["grimage2"])
```
