## Structural Context

| Field | Value |
|---|---|
| **AlphaFold model** | AF-O76024-F1, v6 |
| **pLDDT at residue 30** | **24.59** — **IDR (below 50 threshold)** |
| **Domain** | N-terminal cytoplasmic (intrinsically disordered) |
| **Position context** | N-terminal cytoplasmic (intrinsically disordered) |
| **IDR flag** | YES — pLDDT below 50 (Cat 5) |

**UniProt features at this position:**

  (none catalogued)

> Position 30 sits in N-terminal cytoplasmic (intrinsically disordered). The wild-type residue is small polar (threonine — hydroxyl); the mutant is medium hydrophobic (isoleucine — branched). The chemistry shift implies altered local packing, hydrogen-bonding, and/or electrostatics at this site.

## 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 5 — IDR Exclusion**

<strong>Category 5 — IDR Exclusion</strong><br/><br/>pLDDT 24.59 is below 50; DynaMut2 result not trustworthy. Route to wet-lab.

**Why this card matters.** Position sits in a low-confidence region. Computational stability estimates here are unreliable; this variant needs experimental characterization before any therapeutic strategy is set.
