# ADHD GWAS Summary Statistics (PGC)
Mirror of Psychiatric Genomics Consortium (PGC) summary statistics for
**ADHD** (adhd2022), redistributed in a single Apache Parquet file
for use with [OpenMed Genomics](https://huggingface.co/spaces/turmex2/openneuro-genomics).
## Source
- **Primary citation:** Demontis et al., Nature Genetics 2023
- **Original distributor:** Psychiatric Genomics Consortium
(<https://pgc.unc.edu/for-researchers/download-results/>)
This mirror exists only because the upstream OpenMed mirror became
inaccessible. No modifications have been made to the underlying data;
per-shard parquet files were concatenated into a single file for
convenient streaming.
## File
`pgc-adhd_adhd2022.parquet` -- one Apache Parquet file containing the full summary
statistics table in the PGC's published schema (SNP, CHR, BP, A1, A2,
FRQ, OR/BETA, SE, P, ...).
## Usage
```python
import polars as pl
df = pl.read_parquet(
"https://huggingface.co/datasets/turmex2/pgc-adhd/resolve/main/pgc-adhd_adhd2022.parquet"
)
```
## License & terms of use
PGC summary statistics are released for non-commercial research use only.
Do not attempt to re-identify individuals. Results derived from these
data are **not** a clinical diagnosis. See the original publication for
the full data-use agreement.
