# c.812_835del — WFS1 Molecular Atlas Card

**Variant type:** In-frame indel
**Change:** 8 residue(s) deleted in frame at position 271
**Domain context:** N-terminal cytoplasmic (intrinsically disordered)

---

## Schema category: **I3 — Multi-residue in-frame indel — likely major structural disruption**

8 residues removed in frame around position 271 (N-terminal cytoplasmic (intrinsically disordered)). A change this size usually perturbs local packing and can propagate to the fold. Gene therapy is the primary path unless an AlphaFold prediction of the modified sequence shows a surprisingly intact fold. Predicted structure pending (ColabFold).

## Structural prediction

- **Reading frame:** preserved (in-frame) — no premature stop, NMD does not apply.
- **Affected domain:** N-terminal cytoplasmic (intrinsically disordered)
- **Predicted modified structure:** _pending — AlphaFold/ColabFold prediction of the
  modified sequence and backbone-RMSD vs wild-type backfill here (Wave 2)._
