Is GLA p.Ala350= (c.1050T>C) pathogenic?

GLA p.Ala350= (c.1050T>C) is classified Likely benign in GLA (ClinVar, Multiple submitters, 4 submitters; last evaluated 2025-10-22). Very rare (popmax 0.00349%, afr); Associated with Fabry disease.

What condition is associated with GLA p.Ala350= (c.1050T>C)?

GLA p.Ala350= (c.1050T>C) is associated with Fabry disease (ClinVar).

How common is GLA p.Ala350= (c.1050T>C) in the general population?

GLA p.Ala350= (c.1050T>C) is very rare (popmax 0.00349%, afr) (gnomAD).

How is Fabry disease inherited?

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

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.
