# c.1381_1383del — WFS1 Molecular Atlas Card

**Variant type:** In-frame indel
**Change:** 1 residue(s) deleted in frame at position 461
**Domain context:** Cytoplasmic loop 3

---

## Schema category: **I2 — Single-residue deletion in a soluble domain — variable impact**

A single residue removed in Cytoplasmic loop 3 (a soluble, non-membrane region) may be tolerated or may locally distort the domain. Worth pharmacological-chaperone exploration if AlphaFold predicts a near-native fold. Predicted structure pending (ColabFold).

## Structural prediction

- **Reading frame:** preserved (in-frame) — no premature stop, NMD does not apply.
- **Affected domain:** Cytoplasmic loop 3
- **Predicted modified structure:** _pending — AlphaFold/ColabFold prediction of the
  modified sequence and backbone-RMSD vs wild-type backfill here (Wave 2)._
