# 4p16.3-15.1 duplication — WFS1 Molecular Atlas Card

**Variant type:** Copy-number variant (duplication)
**Region:** Chromosome 4p16.3-15.1 (gene-level structural event)

## CNV-gain — Copy-number duplication — 4p16.3-15.1

This is a large copy-number duplication spanning 4p16.3-15.1 — a gene-level event causing an extra copy of this region (gene over-dosage / partial trisomy). CNVs act by dosage rather than by altering a single residue, so AlphaFold residue mapping, ΔΔG, NMD and AlphaMissense don't apply. Therapeutically these are gene-replacement candidates (restore a working copy); per-residue chaperone/readthrough strategies are not relevant. Confirm breakpoints and gene content against the ClinVar record below.
