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 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); Wolfram syndrome (classic) (autosomal recessive, OMIM 222300). These are two clinically distinct disease families: classic Wolfram syndrome requires two affected copies, while the dominant WFS1-related disorders do not. One label covers both, and it does not tell you which applies to a given person.

- 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 Remaining individuals: AF 0.0048% (3 of 62,494 alleles), 2.2x 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.
