# PGC Major Depressive Disorder — GWAS Summary Statistics
[](https://creativecommons.org/licenses/by/4.0/)
## Dataset Description
Genome-wide association study (GWAS) summary statistics for **Major Depressive Disorder** phenotypes from the [Psychiatric Genomics Consortium (PGC)](https://pgc.unc.edu/).
Each publication is available as a separate subset (config) and can be loaded independently.
## Usage
```python
from datasets import load_dataset
# Load a specific GWAS
ds = load_dataset("OpenMed/pgc-mdd", "AntiDepResponse2021")
print(ds)
```
### List all available subsets
```python
from datasets import get_dataset_config_names
print(get_dataset_config_names("OpenMed/pgc-mdd"))
```
## Subsets
| Config | Phenotype | Journal | Year | PubMed |
|--------|-----------|---------|------|--------|
| `AntiDepResponse2021` | Antidepressant Response | Biol Psychiatry: Global Open Science | 2021 | Pending |
| `mdd2013` | Major Depression | Molecular Psychiatry | 2013 | [22472876](https://pubmed.ncbi.nlm.nih.gov/22472876/) |

## Data Format
All data is stored as **Apache Parquet** shards (10,000 rows each). Common columns:
| Column | Description |
|--------|-------------|
| `SNP` / `ID` | SNP rsID or variant identifier |
| `CHR` | Chromosome |
| `BP` / `POS` | Base-pair position (typically GRCh37/hg19) |
| `A1` | Effect allele |
| `A2` | Non-effect allele |
| `OR` / `BETA` | Odds ratio or effect size |
| `SE` | Standard error |
| `P` | P-value |
| `_source_file` | Original source filename |
> Column names vary between publications. Check each subset's schema.
