## Structural Context

| Field | Value |
|---|---|
| **AlphaFold model** | AF-O76024-F1, v6 |
| **pLDDT at residue 601** | **75.12** — well-folded |
| **Domain** | TM9 (589-609), helical transmembrane |
| **Position context** | TM9 (589-609) |
| **IDR flag** | No — pLDDT above 50 threshold |

**UniProt features at this position:**

  - Chain: 1-890 Wolframin
  - Transmembrane: 589-609 Helical

> Position analysis: ALA602 (2.5 Å), THR600 (2.5 Å), ILE597 (3.8 Å — A598T region). TM9 cluster. The Atlas's neighbor extraction surfaces this variant's contacts and connects them to the broader multi-variant target landscape.

## Research Path Decision Tree

```
ΔΔG < 2  + binding site affected   →  CATEGORY 3 — docking experiments
ΔΔG 2–4                            →  CATEGORY 2 — pharmacological chaperones
ΔΔG > 4                            →  CATEGORY 1 — gene therapy
pLDDT < 50                         →  CATEGORY 5 — IDR, experimental only
Stable fold + functional site hit  →  CATEGORY 4 — site-specific docking
```

## Final Schema Categorization

**Category 4 — Stable Fold, Function Disrupted**

<strong>Cat 4 — see structural prose.</strong> AlphaMissense below threshold (AM under-call class) but mechanism is structurally identified. Therapeutic strategy: site-directed at contacts identified above, or wet-lab validation if pLDDT borderline/below 50.

**Why this card matters.** TM9 multi-variant cluster.
