## Description

Currently, gene aliases retrieval relies on querying the outdated GN3 Rest Server written in Racket:

=> https://github.com/genenetwork/gn3 GeneNetwork3 Racket REST API

For example, using CURL:

```
curl https://genenetwork.org/gn3/gene/aliases/Nr3c1
```

Notable, the same request fails in CD:

```
curl https://cd.genenetwork.org/gn3/gene/aliases/Nr3c1
```

The issue arises from the old, unmaintained service running on tux01 with the following Nginx configuration:

```
      location /gn3 {
	      rewrite /gn3/(.*) /$1 break;
	      proxy_pass        http://127.0.0.1:8000/;
	      proxy_redirect    off;
	      proxy_set_header  Host $host;
      }
```

The suggested action is to migrate this setup to the GNU Guile codebase for improved maintenance and compatibility.
