Clinical Evidence
Observed at very low frequency in gnomAD.
ClinVar classifies this variant as Likely benign, but does not state what it is classified for. ClinVar records no condition for this variant. A classification without a phenotype and an inheritance mode cannot be read as a statement about Wolfram syndrome risk or severity.
- 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: 1★ single submitter. ClinVar "conditions" is the union of all submissions; 0–1★ entries are submitted conditions, not documented phenotypes.
Every ancestry group with observed alleles falls below the reporting threshold (min 2 alleles, min 500 sampled) — too sparse to name a highest-frequency population.
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.

Full Variant Card
S846= — WFS1 Molecular Atlas Card
Variant type: Synonymous (silent) Codon: position 846 (Serine, S) — 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 (S846 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.
