Is GLA p.Ser276Thr (c.827G>C) pathogenic?

GLA p.Ser276Thr (c.827G>C) is classified Likely pathogenic in GLA (ClinVar, Single submitter, 1 submitter; last evaluated 2026-09-08). AlphaMissense: likely benign (0.1923); Absent from gnomAD v4.1; Associated with Fabry disease.

What condition is associated with GLA p.Ser276Thr (c.827G>C)?

GLA p.Ser276Thr (c.827G>C) is associated with Fabry disease (ClinVar).

How common is GLA p.Ser276Thr (c.827G>C) in the general population?

GLA p.Ser276Thr (c.827G>C) 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.Ser276Thr (c.827G>C)?

AlphaMissense predicts likely benign (score 0.1923) — an in-silico prediction, not a clinical call.
