GLA p.Gln321Lys (c.961C>A) is classified Uncertain significance in GLA (ClinVar, Single submitter, 1 submitter; last evaluated 2026-09-08). AlphaMissense: likely benign (0.2916); Absent from gnomAD v4.1; Associated with Fabry disease.

What condition is associated with GLA p.Gln321Lys (c.961C>A)?

GLA p.Gln321Lys (c.961C>A) is associated with Fabry disease (ClinVar).

How common is GLA p.Gln321Lys (c.961C>A) in the general population?

GLA p.Gln321Lys (c.961C>A) is absent from gnomAD v4.1 (gnomAD).

How is Fabry disease inherited?

Typically X-linked dominant, X-linked recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about GLA p.Gln321Lys (c.961C>A)?

AlphaMissense predicts likely benign (score 0.2916) — an in-silico prediction, not a clinical call.
