Is GLA p.Asn5Asp (c.13A>G) pathogenic?

GLA p.Asn5Asp (c.13A>G) is classified Conflicting classifications of pathogenicity in GLA (ClinVar, Conflicting submitters, 4 submitters; last evaluated 2026-09-08). AlphaMissense: likely benign (0.0808); Very rare (popmax 0.000335%, nfe); Associated with Fabry disease.

What condition is associated with GLA p.Asn5Asp (c.13A>G)?

GLA p.Asn5Asp (c.13A>G) is associated with Fabry disease (ClinVar).

How common is GLA p.Asn5Asp (c.13A>G) in the general population?

GLA p.Asn5Asp (c.13A>G) is very rare (popmax 0.000335%, nfe) (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.Asn5Asp (c.13A>G)?

AlphaMissense predicts likely benign (score 0.0808) — an in-silico prediction, not a clinical call.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
