# Gene-Disease Association Analysis

**Discipline**: Medical Genetics | **Tools Used**: 4 | **Servers**: 4

## Description

Analyze gene-disease associations: NCBI gene metadata, OpenTargets disease associations, TCGA expression, and Monarch phenotypes.

## Tools Used

- **`get_gene_metadata_by_gene_name`** from `ncbi-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/9/Origene-NCBI`
- **`get_associated_targets_by_disease_efoId`** from `opentargets-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/15/Origene-OpenTargets`
- **`get_gene_expression_across_cancers`** from `tcga-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/11/Origene-TCGA`
- **`get_joint_associated_diseases_by_HPO_ID_list`** from `monarch-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/16/Origene-Monarch`

## Workflow

1. Get gene metadata from NCBI
2. Get disease-target associations from OpenTargets
3. Analyze TCGA cancer expression
4. Check Monarch disease associations

## Test Case

### Input
```json
{
    "gene_name": "TP53",
    "disease_efo": "EFO_0000311"
}
```

### Expected Steps
1. Get gene metadata from NCBI
2. Get disease-target associations from OpenTargets
3. Analyze TCGA cancer expression
4. Check Monarch disease associations

## Usage Example

> **Note:** Replace `<YOUR_SCP_HUB_API_KEY>` with your own SCP Hub API Key. You can obtain one from the [SCP Platform](https://scphub.intern-ai.org.cn).

```python
