AlphaFold wild-type wolframin · the variant site near residue 278 (N-terminal cytoplasmic (intrinsically disordered)) is highlighted. The SpliceAI isoform prediction that resolves the exact structural outcome is computing and backfills here.

SpliceAI isoform prediction

Computational depth pending. The schema call above is from sequence-level analysis. The SpliceAI isoform prediction that resolves the definitive structural/splicing outcome is computing and backfills onto this card (Wave 2).

Therapeutic Implication · S3

SpliceAI returned no usable prediction (no genomic coordinate / SpliceAI record). The canonical splice-region call stands; wet-lab RNA validation is required to resolve the isoform.

Classified forno review status

ClinVar classifies this variant as Pathogenic/Likely pathogenic, 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: no ClinVar review status recorded. ClinVar "conditions" is the union of all submissions; 0–1★ entries are submitted conditions, not documented phenotypes.

Population frequency
Global (all ancestries)
Absent from gnomAD v4
Homozygotes
Not available

No population breakdown — the variant is absent from gnomAD v4, so no ancestry group has an observed frequency.

No homozygotes — the variant is absent from gnomAD v4 altogether.

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.

Variant type: Splice site Boundary: donor (5' splice site) · intronic offset +1 Nearest protein position: ~278 (N-terminal cytoplasmic (intrinsically disordered))


Schema category: S3 — SpliceAI could not score this variant — wet-lab validation

SpliceAI returned no usable prediction (no genomic coordinate / SpliceAI record). The canonical splice-region call stands; wet-lab RNA validation is required to resolve the isoform.


Splice prediction

  • Affected site: donor (5' splice site), canonical (±1/±2 core)
  • SpliceAI: no genomic coordinate / SpliceAI record

Inheritance and scope

Pathogenic/Likely pathogenic — phenotype scope not stated in ClinVar

ClinVar classifies this variant as Pathogenic/Likely pathogenic, 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.
