Computational Predictions
AlphaMissense + AlphaFold card. This variant is mapped from AlphaMissense pathogenicity and AlphaFold confidence. The DynaMut2 ΔΔG stability prediction and the wild-type/mutant structural comparison (dual-pane + bond network) are computed per-variant and backfill here — they require a DynaMut2 submission, unlike the precomputed AlphaMissense score.
Clinical Evidence
Observed at very low frequency in gnomAD.
ClinVar classifies this variant as Uncertain significance for Wolfram syndrome (classic) (autosomal recessive, OMIM 222300); Cataract 41 (autosomal dominant, OMIM 116400); Nonsyndromic hearing loss (DFNA6/14/38) (autosomal dominant, OMIM 600965); WFS1-related diabetes (autosomal dominant); Wolfram-like syndrome (autosomal dominant, OMIM 614296); WFS1-related spectrum (unresolved mode) (dominant or recessive). ClinVar records this under a WFS1-spectrum label that spans both disease families — recessive Wolfram syndrome (biallelic) and the dominant WFS1-related disorders. The label does not resolve which applies, and it is not a severity statement.

- Phenotype scope is interpretation of submitted records. The computed values on this card (AlphaMissense, DynaMut2 ΔΔG, pLDDT) are measurements of the model, not of a patient.
- Presentation cannot be generalised from neighbouring variants: one nucleotide over can present very differently. Structural similarity supports a mechanistic hypothesis, never a phenotype claim.
Review status: 2★ multiple submitters, no conflicts. ClinVar "conditions" is the union of all submissions; 0–1★ entries are submitted conditions, not documented phenotypes.
Highest in East Asian: AF 0.016% (7 of 44,866 alleles), 6.8x the global figure. The global AF describes the general population, not the at-risk group.
No homozygotes reported in gnomAD v4. For a recessive allele this is expected and is not, on its own, evidence either way.

Source: gnomAD r4, retrieved 2026-08-21. Values are allele frequencies. The carrier estimate is derived from the allele frequency (Hardy-Weinberg, ~2·AF) and is an approximation, not a published figure — where a published carrier frequency exists it outranks this column and is cited on the card.
