# K625= — WFS1 Molecular Atlas Card

**Variant type:** Synonymous (silent)
**Codon:** position 625 (Lysine, K) — amino acid unchanged
**Domain context:** C-terminal ER-lumenal (calcium binding, calmodulin, chaperone)

---

## Schema category: **Silent — Silent — no amino-acid change**

No amino-acid change (K625 is unchanged): the codon is altered but the protein sequence is identical to wild-type. No structural, stability or AlphaMissense effect applies. Synonymous variants are typically benign unless they affect splicing or regulatory elements; this one is not adjacent to an exon boundary.
