# PGC Autism Spectrum Disorder — GWAS Summary Statistics

[![License: CC BY 4.0](https://img.shields.io/badge/License-CC_BY_4.0-lightgrey)](https://creativecommons.org/licenses/by/4.0/)

## Dataset Description

Genome-wide association study (GWAS) summary statistics for **Autism Spectrum 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-autism", "asd2017")
print(ds)
```

### List all available subsets

```python
from datasets import get_dataset_config_names
print(get_dataset_config_names("OpenMed/pgc-autism"))
```

## Subsets

| Config | Phenotype | Journal | Year | PubMed | Rows |
|--------|-----------|---------|------|--------|------|
| `asd2017` | Autism Spectrum Disorder | Molecular Autism | 2017 | [28540026](https://pubmed.ncbi.nlm.nih.gov/28540026/) | — |
| `asd2019` | Autism Spectrum Disorder | Nature Genetics | 2019 | [30804558](https://pubmed.ncbi.nlm.nih.gov/30804558/) | — |

## 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.
