Is GLA p.Ser65= (c.195T>C) pathogenic?

GLA p.Ser65= (c.195T>C) is classified Likely benign in GLA (ClinVar, Multiple submitters, 5 submitters; last evaluated 2026-09-08). Ultra-rare (popmax 0.0131%, amr); Associated with Fabry disease.

What condition is associated with GLA p.Ser65= (c.195T>C)?

GLA p.Ser65= (c.195T>C) is associated with Fabry disease (ClinVar).

How common is GLA p.Ser65= (c.195T>C) in the general population?

GLA p.Ser65= (c.195T>C) is ultra-rare (popmax 0.0131%, amr) (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.
