Clinical Evidence
Population frequency too high for a penetrant Wolfram allele — stand-alone benign evidence (ACMG BA1).
ClinVar classifies this variant as Benign for WFS1-related spectrum (unresolved mode) (dominant or recessive); Nonsyndromic hearing loss (DFNA6/14/38) (autosomal dominant, OMIM 600965). 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.

- Presentation cannot be generalised from neighbouring variants: one nucleotide over can present very differently. Structural similarity supports a mechanistic hypothesis, never a phenotype claim.

Highest in Amish: AF 18.09% (165 of 912 alleles), 2.6x the global figure. The global AF describes the general population, not the at-risk group.
4444 homozygotes reported in gnomAD v4 (20 Amish; 55 Middle Eastern; 144 Ashkenazi Jewish; 3554 European (non-Finnish); 209 African / African American; 162 Remaining individuals; 223 South Asian; 49 Admixed American; 28 Finnish). gnomAD excludes individuals with severe pediatric disease, so homozygotes in this dataset argue against a fully penetrant severe recessive phenotype and belong in the clinical picture. This is interpretive signal, not a classification.

Full Variant Card
A575= — WFS1 Molecular Atlas Card
Variant type: Synonymous (silent) Codon: position 575 (Alanine, A) — amino acid unchanged Domain context: Transmembrane helix 9
Schema category: Silent — Silent — no amino-acid change
No amino-acid change (A575 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.
